/*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("
");
");
}
}
The output of above program would be:
