这个scanf的bug是怎么回事儿？

自己的问题~主题帖修改如下

#include<stdio.h>
#include<stdlib.h>
#include<iostream>
#include<string.h>

int i, j, m, n;
int a[25][25];


int main()    {
        scanf("%d %d", &m, &n);               // input
        getchar();
        for(i = 1; i <= m; i ++)    {
            for(j = 1; j <= n; j ++)    {
                scanf("%d", &a[i][j]);              
            }
            getchar();
        }

        printf("\n");
        for(i = 1; i <= m; i ++)    {
            for(j = 1; j <= n; j ++)    {
                printf("%c", a[i][j]);
            }printf("\n");
        }
        system("pause");
        return 0;
}

抱歉~~~

帅哥，那你到底是想用C还是C++，你把stdio和iostream都写上去干嘛？
