in this program of C language we are not using the any king of loop,we are printing the numbers without loop.

    #include

    int main(){
        int num = 1;

        print(num);     //it is a function which is calling the value of printnum.

        return 0;
    }
    int print(num)           //function called from here and here values are defined.
      {
        if(num<=100)    //number less than equal to 100.
        {
             printf("%d ",num);
             print(num+1);   //add 1 to every number after printing it.
        }
    }

Output:
Sample output:
