Exercise C++ (Struct)

 Write a C++ program to declare a structure for a student record consisting of the following fields:

·         RegNo                 //Registration Number

·         Name                   //Name with initial

·         Marks1                 //1^st Assessment marks

·         Marks2                 //2^nd Assessment marks

·         Total                    //Total of two marks

·         Avg                      // Average of two marks

Write a program to keep the records for five students including functions to do the following task.

·         Read the student’s data.

·         Calculate the total marks and average for each student.

·         Display the students’ details.

Print the RegNo, Total and Average of the student in descending order of the total marks. 

Answer

#include<iostream>

using namespace std;

int main(){

            struct data{

            string RegNo;

            string Name;

            int Mark1;

            int Mark2;

            int Total;

            float Avg;

            };

           

            data stud[5];

                       

            for(int i=0;i<5;i++){

                        cout<<"enter student "<<i+1<<" reg no = ";

                        cin>>stud[i].RegNo;

                        cout<<"enter student "<<i+1<<" name = ";

                        cin>>stud[i].Name;

                        cout<<"enter student "<<i+1<<" 1st assesment marks = ";

                        cin>>stud[i].Mark1;

                        cout<<"enter student "<<i+1<<" 2nd assesment marks = ";

                        cin>>stud[i].Mark2;

                       

                        stud[i].Total=stud[i].Mark1+stud[i].Mark2;

                        stud[i].Avg=(stud[i].Total)/2;

                        cout<<endl;

            }

           

            for(int i=0;i<5;i++){

                        for(int j=i+1;j<5;j++){

                                    if(stud[i].Total<stud[j].Total){

                                                data temp;

                                                temp=stud[i];

                                                stud[i]=stud[j];

                                                stud[j]=temp;

                                    }

                        }

            }

           

            cout<<"RegNo\tName\ttotal\tAverage"<<endl;

            for(int j=0;j<5;j++){

                        cout<<stud[j].RegNo<<"\t"<<stud[j].Name<<"\t"<<stud[j].Total<<"\t"<<stud[j].Avg<<endl;

            }
