    average = (v[0] + v[1] + v[2]) / 3;

    printf("total:%d\n", average);

有问题

这题解决了，我问下用scanf_s输入字符数组时，用printf为什么不能输出字符串？#include<stdio.h>
#include<stdlib.h>
int main(void)
{
    int i;
    char str[10] ;
    for (i = 0; i < 10; i++)
    {
        scanf_s("%s", str);
        printf("%s", str);
    }
    system("pause");
}

vs用的才是scanf_s...
