Question

so I have this code:

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

…

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

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

How do I fix it?

Answer 1

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

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

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 );

and:

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