原生“退出与代码3（0x3） [英] Native' has exited with code 3 (0x3)

问题描述

我在调试此代码时遇到以下问题：

I have the following problem when I debug this code:

// Croppen.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include "stdlib.h" 

int i,j,c;
char hex[] = {"header.hex"},
     ziel[] = {"ergebniss.bmp"},
     eingabe[100];
FILE *f,*h;

int _tmain(int argc, _TCHAR* argv[])
{
    {//eingabe des Orginalen Bildnamens
        printf("Bitte geben sie den Bild namen ein. Maxiaml 20 Zeichen, mit '.bmp'\n");

        do { scanf("%s", eingabe); } while ( getchar() != '\n' );

        if ((f = fopen(eingabe,"rb")) == NULL)
        {
            printf("Fehler beim Öffnen von %s\n",eingabe);
            system("exit");
        }
    }

    {//header einlesen
        h = fopen(hex,"wb");
        for (i = 0; i < 52; i++) { putc(getc(f),h); }
    }

    return 0;
}

产生此错误：

'Croppen.exe': Loaded 'C:\Windows\SysWOW64\oleaut32.dll', Symbols loaded (source information stripped).
The program '[2884] Croppen.exe: Native' has exited with code 3 (0x3).

任何人都可以说我的问题在哪里？

Can any one say where my problem is?

我使用MS VS 2010 Prof IDE。

推荐答案

do {
    scanf("%s", eingabe);
} while ( getchar() != '\n');

不是文字逐字读取的幸运选择。你可以做（​​C风格法）：

isn't a lucky choice for reading from file word by word. You could either do (C-style approach):

while (scanf("%s", eingabe) == 1) {
    ...
}

std :: string 和streams（C ++）：

or use std::strings and streams instead (C++):

std::string word;
while (std::cin >> word) {
    ...
}

虽然我想你只想在这种情况下读取一行文件名：

although I think you just want to read 1 line with a filename in this case:

std::string filename;
if (std::getline(std::cin, filename)) {
    ...
}
