关于指针的delete和重复利用

Question

要怎么修改程序呢？

Answer 1

我把程序稍微改了一点，没有再报错了。

 char *ps=new char[5];
    ps[0]='e';
    ps[1]='g';
    ps[2]='g';
    ps[3]='\0';
    //ps="egg";
    cout<<ps<<" and its address is "<<(int *)ps<<endl;
    delete []ps;



    ps=new char[6];
    ps[0]='c';
    ps[1]='a';
    ps[2]='t';
    ps[3]='\0';
    //ps="cat";
    cout<<ps<<" and its address is "<<(int *)ps<<endl;
    delete []ps;
