c的putchar

图中箭头怎么来的？

#include "stdio.h"
main(){
    char c=getchar();
    while (c!=EOF){
        putchar(c);
        c=getchar();
    }
    return 0;
}

输入的字符最后一个虽然数回车，但遇到EOF不是就结束了吗，怎么会多个箭头

MSDN说：The return value is EOF for an error or if the end-of-file character or the end-of-string character is encounteredin the first attempt to read a character.
// Ctrl+Z  必须是输入行第一个字符

而撸主输入的Ctrl+z对应输入的ASCII码对应的就是右箭头 (Ctrl+Y就是↓，详情请查看ASCII码表)
