*/

//get_letter_grade.cpp

/*

Write function code for gpa_to_letter_grade that returns a string and accepts a double gpa parameter

YOU MUST USE A SWITCH STATEMENT

Given a double 3.5 returns the string A

TIP: You'll have to convert the double to an int using multiplication

Table

3.5 to 4 returns an A

3.0 to 3.49 returns a B

1.7 to 2.99 returns a C

1 to 1.69 returns a D

less than 1 returns an F

*/

//main.cpp

//Write include statements

//Write using statements

/*

No loop.

Use GPAs 3.55, 3.01, and 2.3

Three function calls and display the letter grade.

*/

int main()

{

return 0;

=================================

//get_letter_grade.h

string gpa_to_letter_grade(double gpa);

========================

//get_letter_grade.cpp

#include <iostream>
using namespace std;

string gpa_to_letter_grade(double gpa)
{
string str;
if(gpa>=3.5 && gpa<=4)
str="A";
else if(gpa>=3.0 && gpa<=3.49)
str="B";
else if(gpa>=1.7 && gpa<=2.99)
str="C";
else if(gpa>=1 && gpa<=1.69)
str="D";
else if(gpa<1)
str="F";
return str;
}

===============================

// main.cpp

#include <iostream>
using namespace std;
#include "get_letter_grade.h"
int main()
{
cout<<gpa_to_letter_grade(3.55)<<endl;
cout<<gpa_to_letter_grade(3.01)<<endl;
cout<<gpa_to_letter_grade(2.3)<<endl;
  
return 0;
