Template Concept

Write a program to create a Student class having three data members std_rollno, std_name, std_marks, along with two methods set_data() method to assign values in data member and display() method to show data on the console. Above Student class used by two different colleges but some change in a datatype of the data member. College 1 used integer std_marks, whereas college 2 used float std_marks. How to handle this problem using the template concept? Assume suitable data wherever required.

The solution to the Above Question-

#include<iostream>

using namespace std;

template <typename T>

class student

{

    private: int std_roll;

             string std_name; 

             T std_marks;

    public: void set_data(int r,string s,T marks)

            {

                std_roll=r;

                std_name=s;

                std_marks=marks;

            }

            void display()

            {

                cout<<"Roll No: "<<std_roll<<endl;

                cout<<"Name: "<<std_name<<endl;

                cout<<"Marks: "<<std_marks<<endl;

            }

            

};

class college_1: public student<int>

{

    

};

class college_2: public student<float>

{

    

};

int main()

{

    college_1 A;

    college_2 B;

    A.set_data(1045,"Raunit Verma",98);

    A.display();

    cout<<endl;

    B.set_data(1879,"Verma Raunit",86.5);

    B.display();

    return 0;

}

OutPut

Roll No: 1045 Name: Raunit Verma Marks: 98 Roll No: 1879 Name: Verma Raunit Marks: 86.5
