6-5 digital Pyramid (15 points)

This problem required to achieve an output function number n rows pyramid.

Function interface definition:

void pyramid( int n );

Wherein n is a parameter passed in the user, a positive integer [1, 9]. Print out the function of the required number of n rows in the format as shown pyramid sample. Note that each number followed by a space.

Referee test program Example:

#include <stdio.h>

void pyramid( int n );

int main()
{    
    int n;

    scanf("%d", &n);
    pyramid(n);

    return 0;
}

Sample input:

5

Output Sample:
. 1
2 2
. 3. 3. 3
. 4. 4. 4. 4
. 5. 5. 5. 5. 5

void pyramid( int n )
{
	int i,j,s;
	for(i=1; i <= n; i++)	
	{
		s=n-i;
		for(j=0;j<s;j++)
		putchar(' ');	
		for(j=0; j < i; j++)
		printf("%-2d", i); 
		putchar('\n');
	}
