如何在 if 语句中打印消息?
how can I print a message in if statement?
#include <iostream>
#include<string>
using namespace std;
int main() {
string username, password, option, admin, client,type;
cout << "enter the username" << endl;
cin >> username;
cout << "enter the password" << endl;
cin >> password;
cout << "are you admin or client?" << endl;
cin >> option;
if (option == admin) {
cout << "Add a New Account." << endl;
cout << "Modify An Account." << endl;
cout << "Close An Account." << endl;
cout << "List All Accounts." << endl;
}
else if (option == client) {
cout << "Balance Enquiry" << endl;
cout << "Withdraw Amount." << endl;
cout << "Deposit Amount." << endl;
cout << "Transfer from his account to another account." << endl;
}
cout << "Register as admin/client?" << endl;
cin >> type;
cout << "log out" << endl;
return 0;
}
这 2 条消息您是管理员还是客户? && 注册为admin/client?在if语句中没有输入就出现在彼此后面
如果将两个 if 语句检查更改为如下所示:
if (option == "admin") {
...
} else if (option == "client") {
...
}
它可能会工作得更好,因为目前它正在检查空字符串。
