在C ++中变量的输入值始终输出为0

当我将用户输入存储在变量中并输出时， peoples()函数的值为0.

When I store user input in a variable and output it it gives a value of 0 for my peoples() function.

#include <iostream>
using namespace std;

int number1, number2, result;
// My result should like this
void addison()
{
    cout << "Enter first number:";
    cin  >> number1;
    cout << "Enter second number:";
    cin  >> number2;
    result = number1 + number2;
    cout << number1 << "+" << number2 << "= " << result << endl;
}

int name, age;
// This is the problem and always giving value of variable as 0 after inputting value.
void peoples()
{
    cout <<"Enter your name:";
    cin >> name;
    cout <<"Enter your age:";
    cin >> age;
    cout << "Your name is: " << name << " Your age is: " << age << endl;
}

int main()
{
    int input;

    cout<<"People: 1 \n";
    cout<<"People: 2 \n";
    cout<<"People: 3 \n";
    cin>>input;

    switch (input){

        case 1:
            peoples();
            break;
        case 2:
            addison();
            break;
        case 3:
            cout<<"This is people 3";
            break;
        default:
            cout<<"You have entered Invalid Value";
            break;
    }

    cin.ignore();
    cin.get();
}
