Cは配列の反転を実現します

#include <stdio.h>

void array_inversion(int * a, const int len)
{
    
    

    int min = 0;//数组最小下标
    int max = 0;//数组最大下标
    max = len - 1;

    while (min < max)
    {
    
    
        int tmp = a[min];
        a[min] = a[max];
        a[max] = tmp;
        min++;
        max--;
    }

    return ;
}

int main(int argc,char *argv[])
{
    
    
	int a[] = {
    
     11,22,33,44,55,66,77,88,99};
    int len = sizeof(a) / sizeof(a[0]);
	int i;

    array_inversion(a, len);

	for (i = 0; i < sizeof(a) / sizeof(a[0]); i++)
	{
    
    
		printf("a[%d] = %d\n", i, a[i]);
	}
	
    return 0;
}
