Do-while Loop Explained with Syntax and Examples of C programming
In general, statements in a program are executed sequentially. The first statement is executed first, followed by the second, and so on. But in some situations, it is required to execute a block of code over and over again. Loops are used to execute a block of statements a specified number of times until a condition is met.
C supports the following types of loops:
for loop (CLICK HERE)
while loop (CLICK HERE)
do-while loop
DO-WHILE LOOP:
Unlike for and while loops, which test the loop condition at the top of the loop, the do...while loop in C programming checks its condition at the bottom of the loop.
A do...while loop is similar to a while loop, except the fact that it is guaranteed to execute at least one time since the loop is executed once before the condition is tested.
Syntax:
do
{
statement(s);
} while (condition);
NOTE:
In do…while loop, while should be terminated using;
Examples:
To print all numbers from 50 to 30.
# include<stdio.h>
int main()
{
int n; n=50;
do
{
printf("\n%d",n);
n--;
}while (n>=30);
return 0;
}
