Question

USING C++

Create a program that defines a struct for a student. The following data should be part of the struct: studentID (int), gpa(double), fullName(string), units(int).

Instantiate two students and have the user type in information for each, then print both back to the screen afterwards. Input validation: studentID should be positive and have 4 digits, GPA should be between 0 and 4 (inclusive), units should be positive. Have any invalid inputs reentered.

Answer 1

#include <iostream>

using namespace std;

struct Student{
   int studentID;
   double gpa;
   string fullName;
   int units;
};
struct Student getStudent(){
   Student s;
   int id,units;
   double gpa;
   string name;
  
   while(true){
       cout<<"Enter ID: ";
       cin>>id;
       if(id>=1000 && id<=9999)
           break;
       cout<<" Please Enter the ID between 1000 and 9999\n";
   }
   while(true){
       cout<<"Enter Gpa: ";
       cin>>gpa;
       if(gpa>=0 && gpa<=4)
           break;
       cout<<" Please Enter the GPA between 0 and 4\n";
   }
   cout<<"Enter name:";
   cin>>name;
   while(true){
       cout<<"Enter Gpa: ";
       cin>>units;
       if(units>=0)
           break;
       cout<<" Please Enter the Units greater than 0\n";
   }
   s.studentID=id;
   s.gpa=gpa;
   s.fullName=name;
   s.units=units;
   return s;
}
void display(Student &s){
   cout<<"ID: "<<s.studentID<<endl;
   cout<<"Name: "<<s.fullName<<endl;
   cout<<"GPA: "<<s.gpa<<endl;
   cout<<"Units: "<<s.units<<endl;
}

int main(){

   Student s1=getStudent();
   Student s2=getStudent();
   display(s1);
   display(s2);
  
}
