C - Feof(stdin)-how to indicate end of input in Windows?
提问by Randalfien
int x,y,m;
for(;;){
m=scanf("%d %d",&x,&y);
if (m!=2 || m==EOF){
break;
}
else{
printf("/%d/%d/\n",x,y);
}
}
if (feof ( stdin )){
printf("End of input\n");
}else if(m!=2){
printf("There was an error\n");
}
Under linux ctrl+D indicates end of input , and for windows ctrl+z is supposed to do the trick, but it doesn't work. Any ideas?
在 linux 下 ctrl+D 表示输入结束，对于 windows ctrl+z 应该可以解决问题，但它不起作用。有任何想法吗？
回答by usta
Try pressing Enter after Ctrl+z
尝试在 Ctrl+z 后按 Enter
If still no luck, please try the C++ version:
如果还是不行，请尝试 C++ 版本：
#include <iostream>
int x, y;
while ( std::cin >> x >> y )
std::cout << '/' << x << '/' << y << "/\n";
if ( std::cin.eof() )
std::cout << "End of input\n";
else
std::cout << "There was an error\n";
and see if it does better?
看看它是否做得更好？

#include<stdio.h>
#include<conio.h>
void main (void)
{
int x,y,m;
for(x=0;x>=0;x++){
m=scanf("%d %d",&x,&y);
if (m!=2 || m==EOF){
break;
}
else printf("/%d/%d/\n",x,y);
}
if (feof ( stdin )){
printf("End of input\n");
}
else if(m!=2){
printf("There was an error\n");
}
getch();
}
