/*C program for number pyramid using function*/

#include<stdio.h>

void pyramid(int );

int main()

{

 int num;

 printf("Enter the number of rows : ");

 scanf("%d", &num);

 pyramid(num);

 return 0;

}

void pyramid(int n)

{

 int r,c,x=1,y=1;

 for(r=1; r<=n; r++)

 {

  for(c=1; c<=r; c++,x++)

  {

    if(x<=9)

       printf(" %d",x);

    else

    {

       printf(" %d",y);

       y++;

    }

  }

  printf("\n");

 }

}

The output of above program would be:
