Question

Write C++ program (studentsGpa.cpp) uses dynamic allocation to create an array

of strings. It asks the user to enter a number and based on the entered number it

allocates the array size. Then based on that number it asks the user that many times

to enter student’s names.

What you need to do:



Add another array of doubles to store the gpa of each student as you

enter them



You need to display both the student’s name and the gpa.

NOTE:

must use pointer notation not array subscript.

Answer 1

#include <iostream>

using namespace std;

int main()
{
int n;
double *gpa;
string *names;
cout<<"Enter number of students : ";
cin>>n;
  
//creating arrays dynamically
gpa=new double[n];
names=new string[n];
  
//reading names and gpa
for(int i=0;i<n;i++){
cout<<"Enter the name of Student : ";
cin>>(*(names+i));
  
cout<<"Enter the gpa of Student : ";
cin>>(*(i+gpa));
  
}
// prints names and gpa
for(int i=0;i<n;i++){
cout<<(*(names+i))<<"\t"<<(*(i+gpa))<<endl;
}
return 0;
}
