Dec 16, 2024 · The do…while loop is a type of loop in C that executes a block of code until the given condition is satisfied. The feature of do while loops is that unlike the while loop, which checks the condition before executing the loop, the do…while loop ensures that the code inside the loop is executed at least once, even if the condition is false ...

Loops are used in programming to execute a block of code repeatedly until a specified condition is met. In this tutorial, you will learn to create while and do...while loop in C programming with the help of examples.

The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true. The example below uses a do/while loop.

The following are some examples of do-while loop in C programming: 1. Print Numbers from 1 to 5. int i = 1; do { printf("%d ", i); i++; } while (i <= 5); return 0; Starts with i = 1 and increments until i > 5. 2. Sum of First 10 Natural Numbers.

Sep 23, 2017 · A do while loop is similar to while loop with one exception that it executes the statements inside the body of do-while before checking the condition. On the other hand in the while loop, first the condition is checked and then the statements in while loop are executed.

Here is an example program, Menu-Driven Calculator using the do while loop in C programming( In fact, Infinite do loop).

The do-while loop is mostly used in menu-driven programs where the termination condition depends upon the end user. Syntax to use Do While Loop in C: Program to understand do while loop in c: #include <stdio.h> int main() { int j=0; do { printf("Value of variable j is: %d\n", j); j++; }while (j<=3); return 0; } Output: Note: You need to use the ...

Let us try to understand the behaviour of the while loop with a few examples. The following program prints the Hello world message five times. a ++; } while(a <= 5); printf("End of loop"); return 0; } Here, the do-while loop acts as a counted loop. Run the code and check its output −.

Aug 8, 2024 · ‘C’ programming language provides us with three types of loop constructs: 1. The while loop. 2. The do-while loop. 3. The for loop. 1. In while loop, a condition is evaluated before processing a body of the loop. If a condition is true then and only then the body of a …
