Do-While loop in C

3. Do-While loop in Java:

5. Do-While loop in C++:

In C, the do-while loop is similar to other languages, executing a block of code at least once before evaluating the loop condition. The loop continues as long as the condition remains true.

C 
#include <stdio.h>

int main() {
    int count = 0;
    do {
        printf("%d\n", count); // Print the current value of count
        count++;               // Increment count by 1
    } while (count < 5);        // Continue looping as long as count is less than 5
    return 0;
}

Output
0
1
2
3
4

Explanation: In this C example, the do-while loop prints the value of count and increments it by 1 on each iteration. Similar to other languages, the loop body executes at least once, and the loop continues as long as the condition count < 5 remains true.

Do-While loop in Programming

Do-while loop is a control flow statement found in many programming languages. It is similar to the while loop, but with one key difference: the condition is evaluated after the execution of the loop’s body, ensuring that the loop’s body is executed at least once. In this article, we will learn about the basics of Do while loop, its syntax and its usage in different languages.

What is Do-While Loop:

Do-while loop is a control flow statement (or loop statement) commonly found in many programming languages. It is similar to the while loop but with one crucial difference: the condition is evaluated after the execution of the loop’s body. This ensures that the loop’s body is executed at least once, even if the condition is initially false....

Do-While Loop Syntax:

The syntax of a do-while loop is as follows:...

How does Do-While Loop work?

The do-while loop is a control flow construct used in programming to execute a block of code repeatedly until a specified condition becomes false. Here’s how the do-while loop works:...

Do-While Loop in Different Programming Languages:

Do-While loops are fundamental constructs in programming and are supported by virtually all programming languages. While the syntax and specific details may vary slightly between languages, the general concept remains the same. Here’s how Do-While loops are implemented in different programming languages:...

1. Do-While loop in Python:

In Python, there is no native do-while loop construct. However, you can achieve similar functionality using a while True loop and a conditional break statement to exit the loop when the desired condition is met....

2. Do-While loop in JavaScript:

JavaScript’s do-while loop behaves similarly to other languages. It executes a block of code at least once and then evaluates the loop condition. If the condition is true, the loop continues; otherwise, it terminates....

3. Do-While loop in Java:

In Java, the do-while loop is used to execute a block of code at least once before checking the loop condition. It guarantees that the loop body is executed at least once, even if the condition is initially false....

4. Do-While loop in C:

In C, the do-while loop is similar to other languages, executing a block of code at least once before evaluating the loop condition. The loop continues as long as the condition remains true....

5. Do-While loop in C++:

Similar to Java, C++ also supports the do-while loop, which guarantees that the loop body is executed at least once. The loop condition is evaluated after the first execution of the loop body....

6. Do-While loop in PHP:

PHP’s do-while loop is similar to other languages, executing a block of code at least once before evaluating the loop condition. It continues looping as long as the condition remains true....

7. Do-While loop in C#:

In C#, the do-while loop is similar to Java and C++. It executes a block of code at least once before evaluating the loop condition. The loop continues as long as the condition remains true....

Do-While Use Cases:

The do-while loop, which guarantees the execution of its block of code at least once, is beneficial in various scenarios. Here are some common use cases:...
