C Do While Loop

C do while loop

Created By: chatGPT

C provides a control flow statement called the do while loop, which enables you to execute a block of code at least once. The do while loop checks the condition after executing the loop's body, ensuring that the code runs before the condition is evaluated. This is useful in scenarios where you want to ensure the execution irrespective of the condition.

Here’s the syntax for a do while loop:

c do { // Code to be executed } while (condition);

// Example of a do while loop in C
#include <stdio.h>

int main() {
    int count = 1;
    
do {
        printf("Count is: %d\n", count);
        count++;
    } while (count <= 5);
    
    return 0;
}

In this example, the loop will print the value of count from 1 to 5.

The initial value of count is set to 1.
The do block is executed, printing the current value of count.
After printing, count is incremented by 1.
The condition in the while statement (count <= 5) is checked after each execution of the loop.

As a result, you'll see:

plaintext Count is: 1 Count is: 2 Count is: 3 Count is: 4 Count is: 5

Remember that if the condition is initially false, the code inside the do block will still be executed once, but it will not continue to loop afterward. This is the key difference between do while and other loops like while or for, where the condition is checked before executing the block of code.
