A while statement executes its statements as long as a specified condition evaluates to true. A while statement looks as follows:

while (condition) {
                  // code block to be executed
                }

The while loop loops through a block of code as long as a specified condition is true:

In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5:.

The example below uses a do/while loop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested:.

Example:

In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5:

int i = 0;

                  while (i < 5) {
                    printf("%d\n", i);
                    i++;
                  }
