Code immediately exits before allowing getline to get input

Question

I am learning basic C++ and I am trying to prompt the user for two inputs. The first is using cin for an int and the second for a string. The first input works perfectly; however, the second immediately exits. I tried searching online but they were only regarding multiline inputs.

Here is my code:

#include <iostream>
#include <string>

using namespace std;

int main()
{
    std::cout << endl << "Basic example of char/int input: " << endl;
    int age;
    std::cout << "Enter your age: ";
    // std::cin >> age;  This can be used if it is the only input
    std::getline(std::cin, age);
    std::cout << "You are " << age << " years old!" << endl << endl;

    std::cout << "However, if we want a string, we don't use cin..." << endl;
    string name;
    std::cout << "Enter your name: ";
    std::getline(std::cin, name);

    std::cout << "Hello " << name << "!" << endl;
        
    return 0;
}

TLDR: always use std::getline to read ***all*** input. Mixing std::getline and >>.always ends in tears. — Sam Varshavchik, Apr 09 '21 at 00:37
I see, but I still run into an error with trying to store the getline input as an int. Is there a workaround? — Polydynamical, Apr 09 '21 at 00:50
`int get_int(istream& in) { string s; getline(in, s); return stoi(s); }` ... checking for errors is an exercise for the reader. — Eljay, Apr 09 '21 at 01:23
I see, write a function to get the string and convert it to an integer. Thank you! — Polydynamical, Apr 09 '21 at 03:25
