why this program is not working proper?

Question

#include<iostream>
using namespace std;

int student ()
{
int a,r;
char c;
cout<<"Enter the name of student= ";
cin>>c;
cout<<"Enter the roll number of the student = ";
cin>> r;
cout<<"Enter the Age of student = ";
cin>>a;
}

int main()
{
student();
return 0;
}

Answer 1

make it string c instead char c.
Name is a string , not a char.

Also make your function' s return type as void .

Answer 2

And
you are not outputting any values...
Display after taking values..
Like cout<<c;
And add return statement to start function or make it void...
