CrowdforThink : Blog -Four Critical Tips To Learn Programming Faster

Choosing the right career path can be extremely challenging. Finding a job that you actually like will make going to work each day much easier. If you are fascinated by how apps and software programs are constructed, then a career as a computer programmer may be a good idea.

In a recent study, 47 percent of coding newcomers claimed that their main goal was to get an office job that offered high levels of collaboration with other programmers. In the ever-changing landscape of technology, one thing remains constant, the need for experienced coding professionals.

Are you trying to learn how to code? If so, check out these tips on how to make this process easier and faster.

1. Getting to the Heart of Why You Want to Code

Before you start to learn to code, you need to identify why you want to learn this skill. Do you want to build apps

one day ? Are you trying to expand your current skillset to get a better job?

Once you identify why you want to code, it will be much easier to choose a customized plan of attack. If you do want to build apps or games, you need to figure out what programming languages are commonly used in these industries. By doing this, you can hone in on exactly what you need to learn to accomplish your goals.

2. Take Advantage of Free Online Courses

Some people have the misconception that learning how to code will take a lot of money. While there are a number of online college courses specifically designed for beginner programmers, there are just as many free resources. If you want to get your feet wet without paying a lot of money, looking on a website like Udemy or programming Hub is a great idea.

Generally, you can find free courses on everything from HTML to CSS. Using these free courses to get a basic understanding of a particular programming language is essential. Once you have a firm grasp on what a language can do, moving onto more complex paid courses makes sense.

3. Finding Coding Games to Play

Interjecting a bit of fun into the learning of coding can be helpful. Most people will be extremely bored if all they do is looking at a coding book for months on end. Luckily, there are a variety of websites out there like Codecademy that offer great games geared towards programmers.

By making this process fun, you can unlock the power of coding without getting bored. Doing a bit of online research will allow you to find the right coding games to fit your needs. The time and effort you put into this research process will be worth it in the long run.

Top Tips for Learning Java Programming

If you’re here for the top tips, we assume you’re ahead of the “how to learn Java” part and already boarded on your flight of learning Java. In this lesson, apart from just throwing some do’s and don’ts, we’ll be asking some basic questions that will help you align your path with what’s best for you.

Are you following a plan?

Determining your goal and creating a learning strategy is more significant than you can probably think of. Your ambition, execution, and consistency can make or break your career. So if you want to become a full-time Java Developer shadowing a layout/map goes without saying.

Are you a master of the basics?

Mastering the basics doesn’t necessarily mean learning syntax by heart and not be able to do anything with it. It actually means you’re comfortable working with keywords, know the language protocols, smartly use variables and loops. Know how to choose a data structure depending upon a certain problem. Able to implement object orient approach, since Java is an object-oriented language. Understand encapsulation and how to tamper with it. With this much content freely available widely on the web, newbies are most likely to fell prey to learn more in a shorter period of time. However, you need to understand you can’t build a sustainable building over a weak foundation. Hence, it’s forever helpful to give due time to all the concepts in order to truly “master” them.

The Most Important Programming Lesson I Ever Learned

In the fall of 2012, I walked into my graduate advisor’s office and asked her which computer science class she recommended for me to enroll in. I explained that I was a complete novice in programming. She suggested Introduction to C Programming.

After attending a few lectures, I discover that the majority of the students I spoke to in this introductorycourse had some prior experience in programming.

Six weeks and 80 hours of work later, I dropped the course.

Enter spring semester of 2013. I enrolled in an easier computer science course, Introduction to Computer Programming via the Web. I breezed through the first quarter of the course, executing HTML and CSS with ease. Then, we started Javascript (JS). That feeling of constant anxiety and stress from my previous computer science course returned in full fashion. It was too late in the semester to drop the course, so I asked a friend for help.

Learning C++: for Loops

There are two loop constructs in C++. One of them is the while loop and I’ll cover it in a separate article. The other loop construct, and the one I want to discuss in this article, is the for loop.

The for loop is used when you want to iterate, or loop over, a set of statements, a specific number of times. If you are processing the elements of a container, such as an array or a vector, you will want to use a for loop. If you are processing 10 pieces of data received from the program user, you will want to use a for loop.

Examples of situations where you don’t want to use a for loop are when you are processing the data in a file and you don’t know how many pieces of data are in the file or if you are processing data from a user and you don’t know how many data elements will be entered.

for Loops Types

There are two types of for loops. The first type I’ll call variable-controlled. This means that in the for loop you initialize a variable and the value of that variable determines how many times the for loop iterates.

The other type of for loop is a range for loop. This type of for loop iterates over all the elements of a container, such as a vector or an array. You use this type of loop when you want to process every element of a container, starting with the first element and continuing to the last element. Using a range for loop stops any type of logical error you may get from trying to access an element that is beyond the bounds of the container.

The Variable-Controlled for Loop

The most common for loop type is the variable-controlled for loop. A variable is initialized inside the body of the loop to control the number of loop iterations. I’ll call this the loop control variable. You can initialize the loop control variable outside the loop body but then the scope of the variable is not local to the loop, which you probably don’t want.

Here is a syntax template that defines the structure of a variable-controlled for loop:

for (variable-init; condition; variable-modification) {

loop-body;

}

There are four parts to a for loop: 1) the variable initialization, where you assign a value to a variable to control the loop (the loop control variable); 2) the condition you are testing for to stop the loop; 3) the variable modification, where you modify the value of the loop control variable so the condition eventually is true; and 4) the loop body — where the work of the loop is performed.

Learning C++: Table-Driven Selection

The typical way to perform selection (or branching) in C++ is with the if statement. However, for many scenarios that come up consistently, putting the logic into a table is a more efficient way to perform selection in code. In this article I’m going to demonstrate several ways to replace complex if statements with tables.

Direct-Access Tables

The first type of table-driven selection I want to discuss is using direct-access tables. The example I will use to demonstrate direct-access tables is determining the number of days in a month.

The typical approach to this problem, or what I call the Computer Science 101 approach, is to encode the days in a month in an if-else if statement, like this:

if (month == 1) {
  days = 31;
}
else if (month == 2) {
  days = 28;
}
else if (month == 3) {
  days = 31;
}
else if (month == 4) {
  days = 30;
}
else if (month == 5) {
  days = 31;
}
else if (month == 6) {
  days = 30;
}
else if (month == 7) {
  days = 31;
}
else if (month == 8) {
  days = 31;
}
else if (month == 9) {
  days = 30;
}
else if (month == 10) {
  days = 31;
}
else if (month == 11) {
  days = 30;
}
else if (month == 12) {
  days = 31;
}

That’s a lot of code that takes up a lot of space in a program and a lot of time to read through.

An easier way to encode this data is in an array where the array index represents the month number and the element stored at that index is the number of days in that month.

Here is a program that demonstrates how to use an array as a direct-access table for looking up the days in a month:

#include <iostream>
using namespace std;

int main ()
{
  int month = 0;
  int days = 0;
  const int numMonths = 12;
  int monthDays[numMonths] =
    {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
  string another = "y";
  do {
    cout << "Month number to look up? ";
    cin >> month;
    days = monthDays[month-1];
    cout << "There are " << days << " days." << endl;
    cout << "Do another (y/n)? ";
    cin >> another;
  } while (another == "y");
  return 0;
}

Here is an example of the output of this program:

Month number to look up? 7
There are 31 days.
Do another (y/n)? y
Month number to look up? 2
There are 28 days.
Do another (y/n)? n

The complete program using a direct-access table lookup is shorter than just the if-else if statement used above.

5 Variable Declaration and Initialization Problems

In this series, I’m going to present 5 problems in different areas of C++ and then provide the solutions along with my explanations of the solutions. You should try the problems first before looking at the solutions to maximize your learning efforts.

For this first problem set, here are 5 problems to solve on declaring variables and initializing them with data.

Problem 1

Declare variables for integer, double, string, and bool data. These should be declaration statements only. After you’ve declared the variables, write assignment statements to assign data to each variable.

Problem 2

Rewrite your solutions to Problem 1 so that the declaration statement also includes an assignment (initialization) of data to the variable.

Problem 3

Declare and assign data to three integer variables on the same line so that you only declare the data type once.

Problem 4

Declare and initialize variables for integer, double, string, and bool data using the message-passing style of variable initialization.

Problem 5

Rewrite your solution to Problem 5 using curly braces and explain why this is a good way to initialize variables with data.

Problem 1 Solution

This is the most straightforward way of creating variables and assigning data to the variables. Here is one set of solutions to this problem:


int intNumber;

double dblNumber;

string strngVar;

bool boolVar;

intNumber = 100;

dblNumber = 2.22;

strngVar = "Hello, world!";

boolVar = false;

If you are going to follow this pattern to declare and then assign data to variables you should go ahead and do it in one statement, as the solution to Problem 2 demonstrates.
