C提高_day03_二级指针做输入第1种内存模型

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

void main21()
{
    int        i = 0, j = 0;
    int        num = 0;
    char    *tmp = NULL;
    //数组 数组中的每一个元素是指针 指针数组
    char *myArray[] = {"aaaaaa", "ccccc", "bbbbbb", "d11111"};

    //打印
    num = sizeof(myArray)/sizeof(myArray[0]);

    printf("排序之前
");
    for (i=0; i<num; i++)
    {
        //printf("%s 
", myArray[i]);
        printf("%s 
", *(myArray+i) );
    }

    //排序
    for (i=0; i<num; i++)
    {
        for (j=i; j<num; j++)
        {
            if (strcmp(myArray[i], myArray[j]) > 0 )
            {
                tmp = myArray[i];  //注意  交换的是数组元素 交换的是指针的值
                myArray[i] = myArray[j];
                myArray[j] = tmp;
            }
        }
    }

    printf("排序之后
");
    for (i=0; i<num; i++)
    {
        //printf("%s 
", myArray[i]);
        printf("%s 
", *(myArray+i) );
    }

    printf("hello...
");
    system("pause");
    return ;
}

封装成函数：

#include <stdlib.h>
#include <string.h>
#include <stdio.h>

void printMyArray11(char **myArray, int num)
{
    int i = 0;
    for (i=0; i<num; i++)
    {
        //printf("%s 
", myArray[i]);
        printf("%s 
", *(myArray+i) );
    }
}

void sortMyArray11(char **myArray, int num)
{
    int i =0 , j = 0;
    char *tmp = NULL;
    //排序
    for (i=0; i<num; i++)
    {
        for (j=i; j<num; j++)
        {
            if (strcmp(myArray[i], myArray[j]) > 0 )
            {
                tmp = myArray[i];  //注意  交换的是数组元素 交换的是指针的值  //改变指针的指向
                myArray[i] = myArray[j];
                myArray[j] = tmp;
            }
        }
    }
}

void main()
{
    int        i = 0, j = 0;
    int        num = 0;
    char    *tmp = NULL;
    //数组 数组中的每一个元素是指针 指针数组
    char *myArray[] = {"aaaaaa", "ccccc", "bbbbbb", "d11111"};

    //打印
    num = sizeof(myArray)/sizeof(myArray[0]);

    printf("排序之前
");
    printMyArray11(myArray, num);


    sortMyArray11(myArray, num);


    printf("排序之后
");
    printMyArray11(myArray, num);

    printf("hello...
");
    system("pause");
    return ;
}
