关于指针 用字符数组，字符指针变量输入字符串 动态为字符型指针变量分配内存

#include <stdio.h>
#include <iostream>
#include<math.h>
using namespace std;

int main()
{
     //声明字符型数组和指针变量
    char str[10];
    char *strip=str;

    //输入输出
    cout<<"str=";
    cin>>str;      //用字符数组输入字符串
    cout<<"str="<<str<<endl;
    cout<<"strip="<<strip<<endl;
    cout<<"strip=";
    cin>>strip;     //用字符指针变量输入字符串
    cout<<"str="<<str<<endl;
    cout<<"strip="<<strip<<endl;

    //利用指针变量改变其指向字符串的内容
    *(strip+2)='l';
    cout<<"str="<<str<<endl;
    cout<<"strip="<<strip<<endl;

    //动态为字符型指针变量分配内存
    strip=new char(100);
    cout<<"strip=";
    cin>>strip; //用字符指针变量输入字符串
    cout<<"str="<<str<<endl;
    cout<<"strip="<<strip<<endl;
    system("pause");

}

 指针数组呀

#include <stdio.h>
#include <iostream>
#include<math.h>
using namespace std;

int main()
{
         //声明指针数组
    char *colors[]={"Red","Blue","Yellow","Green"}; 
    //指向指针的指针变量
    char **pt;             

    //通过指向指针的变量访问其指向的内容
    pt=colors;
    for (int i=0;i<=3;i++) {
        cout<<"pt="<<pt<<endl;
        cout<<"*pt="<<*pt<<endl;
        cout<<"**pt="<<**pt<<endl;
        pt++;
    }
    system("pause");

}
