C语言-数组、字符指针数组函数接口与使用

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

typedef char* myString;

//#define MY_STRING

#ifdef MY_STRING
void print_arr(int *a, myString *str, char *ch)  //容易理解
#else
void print_arr(int *a, char **str, char *speed)  //接收指针的变量的地址
#endif
{
    int i = 0;
    for(i = 0; i < 4; i++)
    {
        printf("a[%d] = %d ", i, a[i]);
    }
    printf("\n");

    for(i = 0; i < 4; i++)
    {
        printf("str[%d] = %s ", i, str[i]);
    }
    printf("\n");
    for(i = 0; i < 4; i++)
    {
        printf("str[%d] = %s ", i, *(str + i));
    }
    printf("\n");

    for(i = 0; i < 4; i++)
    {
        printf("ch[%d] = %c ", i, ch[i]);
    }
    printf("\n");
    for(i = 0; i < 4; i++)
    {
        printf("ch[%d] = %c ", i, *(ch + i));
    }
} 

int main(void)
{
    int a[4] = {0, 1, 2, 3};
#ifdef MY_STRING
    myString str[] = {"apple", "orange", "banana", "grape"};
#else
    char *str[] = {"apple", "orange", "banana", "grape"}; //字符指针数组
#endif
    char ch[] = {'a', 'b', 'c', 'd'}; //字符数组
    print_arr(a, str, ch);

    return 0;
}
