C do...while loop

C do...while Loop

The do...while loop in C is a type of loop that is similar to the while loop, but with one key difference. In a do...while loop, the condition is evaluated after the body of the loop has been executed. This means that the body of the loop will always execute at least once, regardless of the condition.

Here are the steps involved in the do...while loop:

1. Initialization: The loop control variable is initialized before entering the loop.

2. Execution of the Loop Body: The statements inside the loop are executed.

3. Evaluation of the Condition: After the loop body has been executed, the condition is evaluated.

4. Repetition or Termination: If the condition is true, the loop body is executed again. If the condition is false, the loop terminates.

For example:

int i = 0;
do {
    printf("Value of i: %d\n", i);
    i++;
} while (i < 5);

In this example, the loop body will execute at least once, as the condition is checked after the first iteration.
