指针的总计

这是针对于字符串的指针数组做出的总结

主要有三个例子 

代表了不同的写法

我的编译器是Visual Studio 2019 Community

这是第一段标准的C语言写法

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


int main()
{
int i;
     char p[12][30] = { "January","February","March","April","May","June","July","August","September","October","November","December" };
    printf("please input your number of month:");
    cin >> i;
    char* a;
    a = p[12];
    printf("\n");
    printf("The month is:%s\n", *(p+i - 1))
return0；
}

第二段C++的写法

#include <iostream>
#include<stdlib.h>
#include<stdio.h>
#include<math.h>
using namespace std;
int main（）
{
int i;
    const char* p[12] = { "January","February","March","April","May","June","July","August","September","October","November","December" };
    printf("please input your number of month:");
    cin >> i;
    printf("\n");
    printf("The month is:%s\n", p[i-1]);
return0；
}

第三段也是C++的写法

#include <iostream>
#include<stdlib.h>
#include<stdio.h>
#include<math.h>
using namespace std;
int main（）
{
int i;
    const char* p[12] = { "January","February","March","April","May","June","July","August","September","October","November","December" };
    printf("please input your number of month:");
    cin >> i;
    printf("\n");
    printf("The month is:%s\n", *p+i-1);
return0；
}
