Where to start learning to program?

Organizations are gradually automating monotonous and tiring chores. Therefore, these days, programming is ultra-important.

Computer programming: Summary

Computer programming is conceiving and planning an executable computer program for completing a certain task.

Programming consists of activities like:

1-Analysis
2-Creating algorithms
3-Outlining algorithms’ exactness and resource utilization
4-Execution of algorithms in a preferred programming language (ordinarily spoken of as coding).

The source code of a program is scripted in languages that programmers can understand instead of
machine code that gets immediately executed by the central processing unit. The idea behind programming is to write a series of instructions that computerizes the implementation of an activity. Take, for example, the convoluted functioning of an operating system on a PC.

Every so often, the programming method calls for know-how in more than a few fields like understanding of the
application domain, focussed algorithms, formal logic, and so on.

Responsibilities tied in with programming include:

1-Testing
2-Debugging
3-Source code maintenance
4-Execution of build systems
5-Administration of unoriginal artefacts like the machine code of computer programs.

Frequently, the tasks mentioned above are dubbed as software development activities.

Programming in times gone by

Programmable equipment was present even in the past; as a matter of fact, in the 9th century, the Persian Banu Musa brothers came up with a programmable music sequencer (to be specific, a fully automated flute player), as claimed by the book on ingenious devices. Then, in 1206, an Arab engineer by the name of Al-Jazari devised an automatic drum that was provided with coded instructions so that it would automatically burst into rich, sweet-sounding musical rhythms.

Later on, in 1801, the Jacquard loom was able to create totally novel and unusual weaves just by making alterations to the “program” (which, in this case, was a succession of pasteboard cards with perforations in them.)

On top of that, code-breaking algorithms have been in existence since ancient times. As an illustration, an Arab mathematician Al-Kindi in the 9th century, used a cryptographic algorithm for making sense of encrypted code, in a document on decoding cryptographic messages. He explained cryptanalysis via frequency analysis, the most primitive code-breaking algorithm.

In general, the earliest computer program dates back to 1843, when Ada Lovelace, an expert in mathematics, made an algorithm to work out a sequence of Bernoulli numbers (that Charles Babbage’s analytical engine was trying to resolve.)

Back in the day, facts and figures would be protected and preserved by the use of exterior punched cards that were systematically categorized by putting them in individual program decks.

In the 1880s, Herman Hollerith developed the notion of squirreling away data in machine-readable form.
Afterward, a control panel (plugboard), connected to a 1906 Type I Tabulator empowered it to be programmed for distinct activities.

In the late 1940s, unit record instruments like the IBM 602 and IBM 604 were supplied with coded instructions in a similar fashion by the use of control panels.

Nevertheless, the abstract idea of the stored-program computers suggested in 1949, set aside and controlled data in the same way as computer memory.

Machine code was the non-verbal system of communication of premature programs, that noted down as per the instruction arrangement of a specified machine, and frequently made use of binary notation.

Before long, Assembly languages became more elaborate that let the programmer clearly identify the instruction in a text format (for example, ADD X, TOTAL), with short forms for every single operation code and suggestive names for identifying addresses.

Be that as it may, an assembly language is not just a system of symbols for a machine language. Two machines with contrasting instruction sets also have non-identical assembly languages.

Coding and programming: Their dissimilarities

Though coding and programming are closely linked, they are not the same. Coding corresponds to writing codes (the initial steps of computer programming), that is rendering the requirements into machine-readable codes. Programming, on the other hand, refers to the process of writing computer programs so that equipment or applications can run without any errors.

Programming styles

It could be that the programming style (employed in a specific program) is acquired from either the coding standards of a business, a different computing establishment, or the inclinations of the writer of the code.

Every so often, programming styles are put together for a particular programming language (or language family). Take, for example, a programming style that is believed to be effective in C source code may not be suitable for BASIC source code, etc. Nonetheless, keeping an eye on the following constituents are useful for a number of languages.

1-Arrangement of the source code, taking account of indentation.
Indentation styles help in recognizing control flow and blocks of code.
2-Application of white space near operators and keywords.
3-Capitalization or otherwise of keywords and variable names
4-Style and spelling of user-defined identifiers like function, procedure, and variable names.
5-Usage and style of comments.

Programming languages: A general idea

Disparate programming languages back diverse styles of programming (known as programming paradigms).
Selecting a programming language depends on facts like company guidelines, appropriateness for the task, accessibility of third-party packages, or personal biases.

**Computer programming: Making a start **

Individuals interested in programming must start from the beginning. First of all, they must make their minds up about what they would like to carry out with their programming expertise. Would they like to invent new games, or are they drawn more towards web development?

It is advisable to start looking carefully at the pertinent programming languages; as an illustration, for games development, it is advantageous to study one of the C languages.

People interested in creating computer software can find helpful resources on YouTube, Udemy, Stack Overflow, Codecademy, Udacity, Team Treehouse, and Khan Academy, etc.

Conclusion

Delving into computer programming can be a very worthwhile involvement. Many famous programmers of today started out with a modest understanding of programming and its many languages but were keen to investigate, hit the books, learn, experiment, analyse, and engage in practice sessions.

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.

Learn to Program Better with The Weekly Spot Drill

Most of us have fallen into this trap. We’re so focused on learning a topic or honing a skill that we don’t touch previously learned information for weeks or months.

Web development is a classic example. There are many technologies and topics to learn, and most of us learn them sequentially. You focus on CSS for a while, then put it on hold to learn the intricacies of React. Or take problem-solving. You focus exclusively on problems that involve arrays. Then strings. Then hash tables.

There’s a problem with this approach. Soon comes the day when we need to apply knowledge that we learned a few weeks ago. And we can’t, at least not easily. We’ve forgotten what we’ve learned. We’ve lost our edge.

It doesn’t have to be this way. In part, the solution involves using Anki flashcards on a daily basis. It’s a topic I’ve written about before, and it’s a great way to keep information fresh and top of mind.

The other part of the solution is what I call the “weekly spot drill.” Once per week, work on a project or problem related to something you previously learned — and unrelated to what you’re currently learning about or working on.

If you’re learning JavaScript right now, solve a problem in Python. If you’re solving tons of problems that involve arrays, pick one that involves strings.

The weekly spot drill will keep your skills sharp — ensure that you’re ready, not rusty — and deepen your knowledge. That’s because you’ll uncover another layer each time you revisit a topic. Plus, this practice will teach you to pivot: to use the best tool to solve the problem, not necessarily the one you’re currently focused on.

An example from the game of baseball drives home the point.

Learning C++: Variable Scope

Variable scope refers to the ability of a variable to be “seen” in a program. A variable is seen if, in a specific place in a program, the programmer has access to that variable’s value. There are levels of scope in a C++ program, with the level of scope determining how widely a variable can be seen in a program. In this article I’m going to discuss the different levels of variable scope and why they are important.

The Scope Levels

Here are the three levels of scope in a C++ program: global, local, and block. Global is the most expansive scope and means that any variable declared with global scope can be seen in any place in a program. Local scope usually refers to a variable defined in a function and can be seen throughout that function, but not in other functions. Block scope means a variable was defined within a block of code, such as a for loop or an if statement.

With these definitions out of the way, let’s look at how these different scope levels affect a C++ program.

Global Scope

A variable that has global scope can be seen in any other part of a C++ program, from a function definition to a block of code. A variable that is defined outside of the main function is a global variable.

Here is an example that demonstrates how global scope works:

#include <iostream>
using namespace std;

// global space
int number = 1;
void showValue() {
  cout << "Number accessed from a function: " << number << endl;
}
int main ()
{
  showValue();
  cout << "Number accessed from the main function: "
       << number << endl;
  for (int i = 1; i <= 1; i++) {
    cout << "Number accessed from a block: " << number << endl;
  }
  return 0;
}
