使用getline初始化函数内的字符串成员变量。似乎无法正确提取输入[重复]

我有以下代码提示用户输入他们的猫的年龄和名字:

#include <iostream>
#include <string>

int main()
{
    int age;
    std::string name;

    std::cin >> age;
    std::getline(std::cin, name);
    
    if (std::cin)
    {
        std::cout << "My cat is " << age << " years old and their name is " << name << std::endl;
    }
}

Input:

"10"
"Mr. Whiskers"

Output:

"My cat is 10 years old and their name is "
