批量读取对比文件

批量读取文件对比内容，并将结果写入文件：

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
int main(){
    int i;
    FILE *file1,*file2,*file;
    char ch1,ch2,path1_tail[2000]={0},path2_tail[2000]={0};
    char path[50]="/home/adu/Documents/project/result/v1";

    if((file=fopen(path,"a+"))!=NULL){
        for(i=1;i<=1052;i++){
            int count1=0,count2=0;
            int flag=0;
            char path1[50]="/home/adu/Documents/project/totinfo/outputs/t";
            char path2[50]="/home/adu/Documents/project/totinfo/newoutputs/t";
            sprintf(path1_tail,"%d",i);
            sprintf(path2_tail,"%d",i);
            strcat(path1,path1_tail);
            strcat(path2,path2_tail);
            if(((file1=fopen(path1,"r"))!=NULL)&&(file2=fopen(path2,"r"))!=NULL){
                while((ch1=getc(file1))!=EOF){
                    count1++;
                }
                while((ch2=getc(f
