Exercise 5-3 Number Pyramid (15 point(s))

This question requires the realization of the function output n-line digital pyramid.

Function interface definition:

void pyramid( int n );

Where n is the parameter passed in by the user, which is a positive integer of [1, 9]. The function is required to print out the n-line digital pyramid in the format shown in the example. Note

It means that each number is followed by a space.

Sample referee test procedure:

#include <stdio.h>

void pyramid( int n );

int main()
{
    
        
    int n;

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

    return 0;
}

Input sample:

5

Sample output:

    1 
   2 2 
  3 3 3 
 4 4 4 4 
5 5 5 5 5 

answer:

void pyramid( int n )
{
    
    
	int i,s,j; //循环变量
	for(i=1;i<=n;i++) //循环到n(有几行循环几行)
	{
    
    
		for(j=1;j<=n-i;j++) //打印前面空格(空格公式需数数，最后一排是没空格第一排在第五个位置打印的所以n-i)
		{
    
    
			printf(" ");
		}
		for(s=1;s<=i;s++) //打印数字后跟一空格
		{
    
    
			printf("%d ",i);
		}
		printf("\n"); //每行打印完需换行
	}
}
