What are uses of do while?

Answer 1

A do-while loop is only useful when you want the loop to execute at least once. This is because the conditional expression is evaluated at the end of each iteration, rather than before each each iteration as it is in a for and a while loop.

Answer 2

Hi

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

do

{

<statements>

} while(<condition>);

For example

#include <stdio.h>

void main(){

int count = 5;

int i = 0;

do{

i++;

printf("%d\n",i);

}while(i < count);

}

The output will be:

1

2

3

4

5

The point to be noted here is that do.. while() is an exit-controlled loop. This means that the condition is tested only after the first iteration of the loop is executed. Hence even if the condition if false, the loop will run at least once.

Answer 3

In programming the function is a named section of programming that completes the designated task, in this occupation the function is also a procedure or routine to be carried out in programming.

Answer 4

int i=1; while (i<=5) { printf("%d",i); i++; int i=1; do { printf("%2d",i); i++; } while(i<=5);

Answer 5

do...while is a one kind of exit control loop.

Answer 6

iteration, also known as looping or cycling
