How can I call out a string from an object array?

Question

I have recently started some OOP in C++, and I was trying to make a small program in Dev-C++ to store arrays of information on employees through a friends function. The code is rough and could use improvements, but I'm not too proficient at it.

#include <iostream>
using namespace std;

class employee{
    int id;
    string names[5];
    float salary;

    public:

        friend void input();
        friend void output();
};

void input(){
    employee obj[5];
    cout << "enter employee id, name and salary\n";
    for(int i=0; i<5; i++){
        cin>>obj[i].id>>obj[i].names[i]>>obj[i].salary;
    }
}

void output(){
    employee obj[5];
    for(int i=0; i<5; i++){
        cout<<"\nwelcome "<<obj[i].name[i]<<endl<<"your id is: "<<obj[i].id<<" and your salary is: "<<obj[i].salary<<"PKR"<<endl;
    }
}

int main(){

    input();
    output();
}

The particular issue is that it doesn't call out the string names for some reason, and I've tried a lot of different ways to rewrite it. Am I just approaching this wrong?

Answer 1

employee obj[5]; is local to each functions. You should declare that in main() and pass that as an argument.

void input(employee obj[]){
    cout<<"enter employee id, name and salary\n";
    for(int i=0;i<5;i++){
        cin>>obj[i].id>>obj[i].names[i]>>obj[i].salary;
    }
}
void output(employee obj[]){
    for(int i=0;i<5;i++){
        cout<<"\nwelcome "<<obj[i].name[i]<<endl<<"your id is: "<<obj[i].id<<" and your salary is: "<<obj[i].salary<<"PKR"<<endl;
    }
}
int main(){
    employee obj[5];
    input(obj);
    output(obj);
}
