✅What is C Programming?
C is a widely-used general-purpose programming language that is easy to learn and use. It is a machine-independent structured programming language which is used to create a variety of applications, operating systems such as Windows, and other complicated software such as the Oracle database, Git, Python interpreter, and others. C can be considered a programming foundation. If you know ‘C,’ you’ll have no trouble learning the other programming languages.

✅What is Stack and Heap Memory?
Stack memory area uses LIFO (Last In First Out) or FILO (First In Last Out) principles for allocating memory to local variables. Stack memory manages the allocation of Static variables, whereas heap memory manages the allocation of dynamic variables. Heap memory area lasts until the memory is released using free() function or until the program is running. In contrast to that stack memory deallocates memory based on LIFO or FILO principle.

Authentication In MEAN Stack - A Quick Guide

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.

To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.

Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Let me show what I mean…

There are template parser errors that can be easy catched by stackblitz

It gives me some information but I want the error to be highlighted

Data Visualization in R with ggplot2: A Beginner Tutorial

A famous general is thought to have said, “A good sketch is better than a long speech.” That advice may have come from the battlefield, but it’s applicable in lots of other areas — including data science. “Sketching” out our data by visualizing it using ggplot2 in R is more impactful than simply describing the trends we find.

This is why we visualize data. We visualize data because it’s easier to learn from something that we can see rather than read. And thankfully for data analysts and data scientists who use R, there’s a tidyverse package called ggplot2 that makes data visualization a snap!

In this blog post, we’ll learn how to take some data and produce a visualization using R. To work through it, it’s best if you already have an understanding of R programming syntax, but you don’t need to be an expert or have any prior experience working with ggplot2

Types of Loops in C and C++? - DZone IoT

Loops in a programming language is a piece of code that get executed repeatedly until the specified condition becomes false. A loop consists of two parts, a block of statements and a condition that control the loop.

Loops mainly consisted of three statements – initialization condition, test condition, update condition.

For example, if we want to print “Hello Codies” 5 times, we can do this in two ways. Writing the statement 5 times (#1) or use loops which save time and effort (#2).

Java

1

#1

2

3

#include <stdio.h> 

4

int main() 

5

{ 

6

     printf("Hello Codies\n"); 

7

     printf("Hello Codies\n");

8

     printf("Hello Codies\n");

9

     printf("Hello Codies\n");

10

     printf("Hello Codies\n");

11

12

    return 0; 

13

}

Java

1

#2

2

3

#include <stdio.h> 

4

5

int main() 

6

{ 

7

  int i; 

8

9

    // Writing a for loop 

10

    // to print Hello Codies 5 times 

11

12

    for (i = 1; i <= 5; i++) { 

13

        printf("Hello Codies\n"); 

14

    } 

15

    return 0; 

16

}

Output:

Java

1

Hello Codies

2

Hello Codies

3

Hello Codies

4

Hello Codies

5

Hello Codies

In this tutorial, you will learn-

1. Types of Loops
2. While Loop
3. Do-While loop

5. Nested loop
6. Break Statement
7. Continue Statement

Types of Loops in C/C++

Loops are classified into two types depending upon the position control statements:

• Entry controlled loop
• Exit controlled loop

Entry controlled loop: A conditional statement is evaluated before executing the body of a loop. It is also called as a pre-checking or Counter controlled loops where the programmer already know how many times the loop get executed. Counter controlled loops are often called definite iteration because the number of repetitions is known before the loop begins execution.

Exit controlled loop: In this type of loops conditional statement are evaluated after executing the loop body once irrespective of whether the test condition is true or false. It is also called as a post-checking or Sentinel controlled Loop because the programmer don’t know exactly know how many times loop will be executed. Sentinel-controlled loop also known as indefinite repetition.

The control conditions must be specified properly otherwise the loop will execute infinite number of times (infinite loop). An infinite loop occurs when no termination condition is specified or specified conditions never meet.

C programming language provides us with 3 types of loop and C++ has 4th extra loop:

• while loop
• do-while loop
• for loop
• Nested Loop (only in C++)

The syntax of these loops mainly differs in the placement of these three statements initialization condition, test condition, update condition.

While Loop in C/C++

The while loop specify that a program should repeat set of instruction inside the block till the condition remains true. While loop used in place where we don’t know number of iteration before and it depends on the update inside the block. While loop is Entry Controlled loop and widely used in C/C++.

Syntax of WHILE Loop:

Java

1

initialization condition;

2

while (test_ condition)

3

{

4

   // statements

5

6

  update_ condition;

7

}

Flow Chart of While loop.

In While loop, condition evaluated first if condition is TRUE than block of statements get executed and update condition then control again goes back at the beginning, and the condition is checked again if it is true, the same process is executed until the given condition becomes false. Once the test condition results FALSE control goes back to main program. While Loop is Entry-Controlled Loop.

Note: If Loop contains only one statement, then the curly braces are not compulsory. Though It is a good practice to include braces.

Following program illustrates a while loop:

Java

1

#include<stdio.h>

2

3

int main()

4

{

5

  int num=1;    //initializing the variable

6

7

     while(num<=5)            //while loop with test condition

8

    {

9

       printf("%d ",num);  

10

       num++;        //incrementing (update condition)

11

    }

12

    return 0;

13

}

Output:

Java

1

1 2 3 4 5

The above program prints series of numbers from 1 to 5 using a while loop.

Let’s see what happening in above program step by step.

Step 1: We have initialized variable ‘num = 1’.

Step 2: In while condition we are evaluating is ‘num’ value is less than or equal to 5, if ‘num’ becomes greater than 5 than this condition become False.

Step 3: For now ‘num = 1’, we enter the loop comparing 1 <= 5 which result true so the body of loop i.e. ‘num’ value 1 got printed.

Step 4: In this step ‘num’ value increased by 1 i.e now ‘num = 2’.

Now step 3 get repeated again with ‘num = 2’ and print the ‘num’ value 2, similarly 3,4,5. When ‘num’ got increase to 6 (num =6) while condition become FALSE & loop terminated than control goes back to main() function as there is nothing after loop do program exits with returning 0 indicating that everything went well.
