自制对数器

假如有一个output上万行的模拟，然后case过不去，就要用到对数器了~

#include<iostream>
#include<cstdio>
using namespace std;
int main(void)
{
    FILE * fp1,fp2;
    fp1 = fopen("C:\\Users\\saS\\Desktop\\666.txt","r+");
    fp2 = fopen("C:\\Users\\saS\\Desktop\\777.txt","r+");
    ch1 = fgetc(fp1);
    ch2 = fgetc(fp2);
    while(ch1!=ch2)//从文本文件中读取数据
    {
        //.....
        ch1 = fgetc(fp1);
        ch2 = fgetc(fp2);

    }
        fclose(fp1);
        fclose(fp2);
        return 0;
}
