Answer to Question #203729 in C++ for python

Question

Define a class student with the following specification. Note for user understanding purposes you

should write comment with each line of code.

Private members of class student

admno integer

sname 20 character

eng. math, science float

total float

ctotal() a function to calculate eng + math + science with float return type.

Public member function of class student

Takedata() Function to accept values for admno, sname, eng, science and invoke

ctotal() to calculate total.

Showdata() Function to display all the data members on the screen.

Answer 1

#include <iostream>




using namespace std;


class Student {
private:
	int admno;
	char sname[20];
	float eng;
	float math;
	float science;
	float total;


	float ctotal() {
		return eng + math + science;
	}


public:


	void Takedata(int admno, char sname[20], float eng, float math, float science) {
		this->admno = admno;
		strcpy(this->sname, sname);
		this->eng = eng;
		this->math = math;
		this->science = science;
		this->total = ctotal();
	}
	void Showdata() {
		cout<<"\nAdmno: " <<admno<<"\n";
		cout<<"Name: " <<sname<<"\n";
		cout<<"Eng: " <<eng <<"\n";
		cout<<"Math: " <<math <<"\n";
		cout<<"Science: " <<science <<"\n";
		cout<<"Total: " <<total <<"\n";
	}
};
//The start point of the program
int main(){
	Student st;
	int admno;
	char sname[20];
	float eng;
	float math;
	float science;
	cout<<"Enter admno: ";
	cin>>admno;
	cin.ignore();
	cout<<"Enter sname: ";
	gets(sname);
	cout<<"Enter eng: ";
	cin>>eng;
	cout<<"Enter math: ";
	cin>>math;
	cout<<"Enter science: ";
	cin>>science;
	st.Takedata(admno, sname, eng, math, science);
	st.Showdata();
	cout<<"\n\n";


	system("pause");
	return 0;
