输入一个字符，把这个字符按几排几列输出

#include "pch.h"
#include <iostream>
void chline(char chch,  int n,  int m);
int main()
{
    std::cout << "Hello World!\n"; 
	int chch;
	 int n, m;
	 while ((chch=getchar())!='\n')
	 {
		 if (scanf_s(" %d %d", &n, &m)!=2)
		 break;
		 chline(chch, n, m);
		 while (getchar()!='\n')//跳过最后的enter键
			 continue;
	 }
	 getchar();
	 return 0;
}
void chline(char chch,  int n,  int m)
	{
	printf("*****************************************\n\n");
	//char ch = chch;
	int i;
	int in;

		for (i = 1; i <= n; i++)//n代表几排
		{	
			for ( in = 1; in <= m; in++)//m代表几列
				printf(" %c   ",chch);
			putchar('\n');
				//printf("%c",chch);
		}
	printf("*****************************************\n\n");
	}

效果图如下
