Visual Studio 2012中的strcpy()错误 [英] strcpy() error in Visual studio 2012

问题描述

所以我有这个代码:

#include "stdafx.h"
#include <cstdlib>
#include <iostream>
#include <string>
using namespace std;

...

char* b = new char [10];
strcpy(b, "1234567890");

错误:Microsoft Visual Studio 11.0 \ vc \ include \ string.h(110):请参见'strcpy'的声明

error: microsoft visual studio 11.0\vc\include\string.h(110) : see declaration of 'strcpy'

我该如何解决?

推荐答案

在MSDN上有对此的解释和解决方案:

There's an explanation and solution for this on MSDN:

由于存在以下事实，函数strcpy被认为是不安全的没有边界检查，并可能导致缓冲区溢出.

The function strcpy is considered unsafe due to the fact that there is no bounds checking and can lead to buffer overflow.

因此，如错误描述中所建议，您可以使用strcpy_s而不是strcpy:

Consequently, as it suggests in the error description, you can use strcpy_s instead of strcpy:

strcpy_s(char * strDestination，size_t numberOfElements，
const char * strSource);

strcpy_s( char *strDestination, size_t numberOfElements,
const char *strSource );

和:

要禁用弃用，请使用_CRT_SECURE_NO_WARNINGS.有关详细信息，请参见在线帮助.

To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
