好的,以下是一个简单的网站新用户注册程序的代码,包含指针和结构体:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
typedef struct {
char username[20];
char password[20];
char email[30];
} User;
int main() {
User *newUser = (User *)malloc(sizeof(User));
printf("Welcome to our website! Please enter your information to register:\n");
printf("Username: ");
fgets(newUser->username, 20, stdin);
newUser->username[strcspn(newUser->username, "\n")] = '\0';
printf("Password: ");
fgets(newUser->password, 20, stdin);
newUser->password[strcspn(newUser->password, "\n")] = '\0';
printf("Email: ");
fgets(newUser->email, 30, stdin);
newUser->email[strcspn(newUser->email, "\n")] = '\0';
printf("Congratulations! You have successfully registered with the following information:\n");
printf("Username: %s\n", newUser->username);
printf("Password: %s\n", newUser->password);
printf("Email: %s\n", newUser->email);
free(newUser);
return 0;
}
```
程序首先定义了一个名为 User 的结构体,包含了用户名、密码和电子邮件等信息。接着用 malloc 函数动态分配内存给 newUser 指针,以存储新用户的信息。然后程序通过 fgets 函数获取用户输入的信息,并将输入的换行符替换为字符串结束符。最后输出注册成功的信息,包括用户名、密码和电子邮件,同时释放 newUser 指针所指向的内存。
