#include <stdio.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]);
