关于文件处理的问题 [英] question about file handling

问题描述

#include <iostream.h>
#include <fstream.h>
#include <conio.h>
void main()
{
clrscr();
char ch;
ofstream sc;
sc.open("om.txt");
while(ch!='1')   //here is the problem
{
ch=getche();
sc.put(ch);


}
sc.close();
getch();
}

以上在文本文件om.txt中一次输入一个字符。问题是，当我按两次时，程序没有被正确地删除，然后编程terimate

The above enters one character at a time in text file om.txt. Problem is that program is not correctly teriminated when i press two time 1 then program terimate

推荐答案

可能是因为你通过调用来结束程序的getch 。这也会在键盘继续之前从键盘上读取一个字符...

Probably because you end the program with a call to getch. This also reads a character from the keyboard before it continues...

你检查字符'1'但你应该检查数字1.



请确保使用getche（）获取正确的字符：

you check for the char '1' but you should check for the digit 1.

Be sure that you are fetching the proper char with getche():
