C Program to Print 1 to 100 Numbers without using Loop

Write a C program to print 1 to 100 numbers without using loop. In this tutorial, we going to learn how to write a C code to print 1 to 100 number without using loop (for, while etc).

How do we print numbers from 1 to 100 without using loop? Writing c program to print 1 to 100 numbers using loop is very simple. This problem can be solved using recursion.

MCQ on recursion for practice.


C Program to Print 1 to 100 Numbers without using Loop



Let's write a code to print 1 to 100 numbers without using loop.

#include <stdio.h>

void printNumbers(int num) {
 
  //If num is less than or equal to 100
  if(num <= 100) {
      
      //print number  
      printf("%d ", num);

      //Recursively call
      printNumbers(num+1);
   } 
}

int main(void) {
 
    int n = 1;
 
    //Call method to print number
    printNumbers(n);
 
    return 0;
}



In the above program, we created a function printNumbers(int num) and passed 1 in an argument from main method.

Another way of writing this program.

#include <stdio.h>

void printNumbers(int num) {
 
  //If num is less greater than or equal to 1
  if(num >= 1) {

    printf("%d ", num);

    /*Recursively call,
      Decrement the value by 1 
    */
    printNumbers(num-1);
  } 
}

int main(void) {
 
  //Call method to print number
  printNumbers(100);
 
  return 0;
}
