d: 一个数字,每个用户不同的id
email: email地址,一般网站的用户允许以email地址登录
gender: 性别,男or女

写一个函数,在User数组中查找某个id的User
函数描述:
User* find (User* all, int n, int id);
其中,
all: 输入一个User数组
n : 数组长度
id: 待查找的id
#include<iostream> #include<string> using namespace std; struct User { int id; string email; string gender; long int qq; }; User* find(User* all, int n, int id) { for (int i = 0; i < n; i++) { if (all[i].id == id) { cout << all[i].id << " " << all[i].email << " " << all[i].gender << " " << all[i].qq << " " << endl; } }return 0; } int main() {struct User s[3]={{123,"qwe","男",147258}, {456,"asd","男",147369}, {789,"zxc","男",258369} }; find(s, 3, 123); return 0; }
