Sample C Program to Print 1 to 100

In this article, we will show you, How to write a Sample C Program to Print 1 to 100 without using For Loop, Do While and While Loop with an example.

Sample C Program to Print 1 to 100 without using Loop

In the example, we are going to write a C Program to Print 1 to 100 without using Loops.

/* Sample C Program to Print 1 to 100 without Loop */

#include<stdio.h>
int print (int number);
int main()
{
    int num = 1;
    print(num);
    return 0;
}
int print (int number)
{
    if(number <= 100)
    {
       printf("%d\t", number);
       print(number + 1); // Calling Function recursively
    }
}

OUTPUT

ANALYSIS

When the compiler reaches to print(num) line in main() program then the compiler will immediately jump to below function:

int print (int number)

Within the function we used the If Statement to check the number is less than or equal to 100 or not. If the condition returns TRUE then statements inside the If will be executed.

if(number <= 100)
  {
     printf("%d\t", number);
     print(number + 1); // Calling Function recursively
  }

Within the If block, we used the print(number + 1) statement, that will help to call the function Recursively with the updated value. If you miss this statement then after completing the first line it will terminate, and the output will be 1. Please refer Recursion in C article to understand the recursive function.
