id and name are only accessible from the input method; you'll have to make them accessible from output too, for example:

C++

int id;
char name[20];

void input()
{
    cout<<"Enter the student id:"<<endl;
    cin>>id;
    cout<<"Enter the student name:"<<endl;
    cin>>name;
}
void output()
{
    cout<<"The Student id is: "<< id <<endl;
    cout<<"The Student name is: "<< name <<endl;
}
