大神帮忙看一下这里哪错了？生成解决方案没问题，但是运行就出现“20170901.exe 中的 0x5340d540 (msvcr100d.dll) 处有未经处理的异常: 0xC0000005: 读取位置 0x00000000 时发生访问冲突” 这种情况！
#include <iostream>
#include <cstring>
int main()
{
    using namespace std;
    char animal[20]="bear";
    const char* bird="wren";
    char*ps=NULL;

    cout<<animal<<" "<<bird<<" "<<ps<<endl;

    cin>>animal;
    ps=animal;
    cout<<ps<<endl;
    cout<<animal<<" "<<(int*)animal<<endl;
    cout<<ps<<" "<<(int*)ps<<endl;

    ps=new char[strlen(animal)+1];
    strcpy(ps,animal);
    cout<<animal<<(int*)animal<<endl;
    cout<<ps<<" "<<(int*)ps<<endl;

    delete []ps;
    system("pause");
    return 0;
