能帮忙看看嘛 运行了好几次
都是“Can’t open t1.txt”
难道结果就是这样吗 好奇怪
#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
int main() {
FILE *fp1,*fp2;
unsigned char ch;
fp1=fopen("D:\t1.txt","rb");
if(fp1==NULL) {
printf("Can't open t1.txt");
exit(1);
}
fp2=fopen("D:\t2.txt","wb");
if(fp2==NULL) {
printf("Can't open t2.txt");
// exit(1);
}
while(!feof(fp1)) {
ch=fgetc(fp1);
if((int)ch!=0&&(int)ch!=0){
ch=~ch;
ch=ch<<5;
fputc(ch,fp2);
}
}
fclose(fp2);
fclose(fp1);
return 0;
}
unsigned char shift_fun1() {
unsigned char i;
unsigned char src=0x00;
unsigned char des=0;
for(i=0; i<8; i++) {
if(src&0x1)
des |=1<<(7-i);
else
des &=-(1<<(7-i)) ;
src >>=1;
}
printf("%x\n",des);
return des;
}
