问题描述

c++中用vs2013时strcpy_s的问题

#include
#include
int main()
{
using namespace std;
char animal[20] = ""bear"";
const char * bird = ""wren"";
char * ps;

cout << animal << "" and "";cout << bird << ""n"";cout << ""Enter akind of animal: "";cin >> animal;ps = animal;cout << ps << ""!n"";cout << ""Before using strcpy():n"";cout << animal << "" at "" << (int*)animal << endl;cout << ps << "" at "" << (int*)ps << endl;ps = new char[strlen(animal) + 1];strcpy_s(ps 20 animal);                   //为什么20改成strlen(animal)+1之后输入后按下回车就结束了cout << ""After using strcpy():n"";cout << animal << "" at "" << (int*)animal << endl;cout << ps << "" at "" << (int *)ps << endl;delete[] ps;cin.get();return 0;

}

这段代码运行不正常，我用的vs2013

解决方案

 用sizeof(animal)
