加密文件程序，错误如下，帮忙看下
#include<stdio.h>#include<stdlib.h>
void main(int argc,char*argv[]) //argc为整数，argv 为指针的指针
{
FILE *fp1,fp2;
char c,ch;
long j;
if(argc!=3)exit(0);
fp1=fopen(argv[1],"rb"); //打开文件供读
fp2=fopen(argv[2],"wb"); //打开文件供写
if((fp1==NULL)||(fp2==NULL))
{
printf("cannot open file\n");
exit(1);
}
printf("请输入密码：");
scanf("%i",&j);
srand(j); //初始化随机数发生器
ch=fgetc(fp1); //ch为文件字符流
while(!feof(fp1))
{
c=rand(); //c为随机字符流
ch=ch^c; //异或加密
fputc(ch,fp2);
ch=fgetc(fp1);
}
fclose(fp1);
fclose(fp2);
exit(0);
}
