下面问题改了再说

除此之外, 这篇博客: C语言给结构体赋数据值和带有结构体指针变量的赋值方法中的 C语言结构体指针变量作函数参数 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:

#include <stdio.h>
struct stu
{
    int num;
    char *name;
    char sex;
    float score;
} boy[5] = {
    {101, "Li ping", 'M', 45},
    {102, "Zhang ping", 'M', 62.5},
    {103, "He fang", 'F', 92.5},
    {104, "Cheng ling", 'F', 87},
    {105, "Wang ming", 'M', 58}};

void Fve(struct stu *ps)
{
    int c = 0, i;
    float ve, s = 0;
    for (i = 0; i < 5; i++, ps++)
    {
        s += ps->score;
        if (ps->score < 60)
            c += 1;
    }
    printf("s=%f\n", s);
    ve = s / 5;
    printf("average=%f\ncount=%d\n", ve, c);
}

main()
{
    struct stu *ps;
    void Fve(struct stu * ps);
    ps = boy;
    Fve(ps); 
}

执行结果：

s=345.000000
average=69.000000
count=2
