C Primer Plus学习结构和其他数据类型（7）

使用结构数组的函数：

#include 
#define FUNDLEN 50
#define N 2
struct funds {
    char bank[FUNDLEN];
    double bankfund;
    char save[FUNDLEN];
    double savefund;
};
double sum(const struct funds money [], int n);
int main(void)
{
    struct funds jones[N] = {
        {
            "Garlic-Melon Bank",
            4032.27,
            "Lucky's Savings and Loan",
            8543.94
        },
        {
            "Honest Jack's Bank",
            3620.88,
            "Party Time Savings",
            3802.91
        }
    };
    printf("The Joneses have a total of $%.2f.\n", sum(jones, N));
    return 0;
}
double sum(const struct funds money [], int n)
{
    double total;
    int i;
    for (i = 0, total = 0; i < n; i++)
    total += money[i].bankfund + money[i].savefund;
    return(total);
}

运行结果如下：
