In C The University of Ohio at Dayton determines yearly lab

In C++,

The University of Ohio at Dayton determines yearly lab dues as follows :

Class Level   GPA     Dues Amount
F (Firstyear)   -   $150
S (Second year)   Greater than 3.75   $75
S (Second year)   Greater than >2.50 && less than 3.75   $120
S (Second year)   Less than 2.5   $130
J (Junior)   Greater than 3.75   $50
J (Junior)   Greater than >2.50 && less than 3.75   $100
J (Junior)   Less than 2.5   $125
N (Senior)   Greater than 3.75   $25
N (Senior)   Less than 3.75   $75

For example, a Junior level student named Janice Morgan with a GPA = 3.81, is charged
yearly dues of $50. The program would output :

Janice Morgan/Junior/GPA=3.81 Dues are $50.00
  
Notes :

1.   User is to be prompted for student name, class level and GPA.
2.   The program must use a switch statement to interrogate the class level.
3.   The default case must be included. It outputs an the error message :

INVALID CLASS ENTERED !

4.   Within a case, use an if statement to test the GPA to determine the dues amount.

//Accept data
cout<<\"\ Enter Student name: \";
cin>>stuName;
cout<<\"\ Enter Student Class Level: \";
cin>>classL;
cout<<\"\ Enter Student GPA: \";
cin>>GPA;
//Checks class Level
switch(classL)
{
case \'F\':
