Question

Write a complete C++ program that constructs an array A of 10 elements of type Student. The type Student is a structure of two fields, the first field of type int represents the ID of the student the second field of type float represents the grade of the student. The program contains the following functions:

1- A void function input that enters the elements in the array.

2- A void function output that displays the elements of the array.

Answer 1

code:

#include<iostream>
using namespace std;
struct student
{
   int Id;       //declaring id of type int
   float grade;       //decalring grade of type float
   inputData()       //dunction defination to the inputing data
   {
       cout<<"enter id of student ";
       cin>>Id;       //inputiing id
       cout<<"enter grade of student";
       cin>>grade;       //inputing grade
       cout<<endl;
   }
   outputData()       //function defination to the output daat
   {
       cout<<"ID is :"<<Id<<endl<<"grade is :"<<grade<<endl;
   }
};
int main()
{
   struct student s[10];       //creating array of student of 10 size
   for(int i=0;i<10;i++)
   {
       cout<<"enter student data:"<<i+1<<endl;
       s[i].inputData();       //function call
   }
   for(int i=0;i<10;i++)
   {
       cout<<"student data :"<<i+1<<endl;;
       s[i].outputData();       //function call
   }
}

OUTPUT:

enter student data:1
enter id of student 101
enter grade of student25.36

enter student data:2
enter id of student 102
enter grade of student45.21

enter student data:3
enter id of student 103
enter grade of student78.26

enter student data:4
enter id of student 104
enter grade of student45.36

enter student data:5
enter id of student 105
enter grade of student89.36

enter student data:6
enter id of student 106
enter grade of student45.00

enter student data:7
enter id of student 107
enter grade of student75.00

enter student data:8
enter id of student 108
enter grade of student55.99

enter student data:9
enter id of student 109
enter grade of student82.12

enter student data:10
enter id of student 110
enter grade of student78.12

student data :1
ID is :101
grade is :25.36
student data :2
ID is :102
grade is :45.21
student data :3
ID is :103
grade is :78.26
student data :4
ID is :104
grade is :45.36
student data :5
ID is :105
grade is :89.36
student data :6
ID is :106
grade is :45
student data :7
ID is :107
grade is :75
student data :8
ID is :108
grade is :55.99
student data :9
ID is :109
grade is :82.12
student data :10
ID is :110
grade is :78.12
