在 C++ 中获取用户输入的字符串

Question

This is the piece of code I am getting error in. Yes I have `using namespace std

string age2;

cin.ignore();

getline(cin, age2);

cout << "Your age is " << age2;

This is giving me error -> "getline is not defined"

I tried searching up and tried all the solutions but none of them worked.

Answer 1

This code here works fine:

#include <iostream>
#include <string>

int main(){

std::string age;

std::cin.ignore();

std::getline(std::cin, age);

std::cout << "Your age is " << age;

return 0;
}

so there must be something your missing in your example

also if your doing age, you should use an int instead of a string, like this:

#include <iostream>
#include <string>

int main(){

int age;

std::cin.ignore();

std::cin >> age;

std::cout << "Your age is " << age;

return 0;
}
