In this tutorial you you will be familiarize with one of the iteration statement that is do-while loop which is available in C programming language, along with its syntax and example.
Iteration statement
Iteration statement is defined as the set of instructions that are repeated in a sequence for specific number of times until the condition is satisfied.
When the first set of instructions is executed again, it is called an iteration.
Iteration statements are commonly known as loops.
Also the repetition or iteration processes in C programming language is done by using loop control instruction.
do-while loop statement :
The while loop statement is also known as exit control loop as it first compiles and executes checks the inner body then condition is checked .
The while-loop statement has the following syntax:
while (expression)
{
statement;
// or {block of statements}
}
Example program of do-while loop in C:
A code in C language to determine table of any entered number by user which is less than 100 using iteration.
// Header file which contains functions for standard input and output manipulative operation.
#include <stdio.h>
// Compiling of code start from main function
int main()
{
// Declaration of local variable of data-type int
int num,i=1;
// To display on console screen
printf(“Enter any number…… /n ”);
// To get input from user
scanf(“%d”,&num);
// to check whether the entered number is lesser than 100 or not
if(num <= 100)
{
// i is counter variable
do
{
printf(“%d/n ”,num*i);
i++;
}
while(i>0)
return 0;
}
After compilation and execution of code written above you will get the following output :
OUTPUT :
Enter any number……5 5 10 15 20 25 30 35 40 45 50
