// Program Description:
// --------------------
//      Program determines if a student is eligible for a scholarship
//
// Input Requirements:
// -------------------
//      college: a String, either "CENG" or "COB"
//      GPA: a float >= 0.0 and <= 4.0, cumulative Grade Point Avg.
//
// Output Requirements:
// --------------------
//      Prompt message: "Enter your college, CENG or COB:"
//      Prompt message: "Enter your GPA:"
//      Error message: "Invalid college name,"
//      Error message: "Invalid GPA value,"
//      Answer message: "You are eligible for a CENG scholarship."
//      Answer message: "You are eligible for a COB scholarship."
//      Answer message: "You are not eligible for a scholarship."
//
// Program Preconditions:
// ----------------------
//      None.
//
// Problem Solution Discussion:
// ----------------------------
//     This program prompts the user to enter his or her college and GPA.
//     It then checks if valid inputs have been entered.  If college is not
//     CENG or COB, that's invalid, and an error message is printed.
//     If GPA is less than 0 or greater than 4, that's invalid, and an
//     error message is printed.  If the inputs are valid, the comparisons
//     are made to determine scholarship eligibility.
//     If student is in CENG and GPA is 3.2 or above, then eligible for
//     CENG scholarship and message is printed.
//     If student is in COB and GPA is 3.3 or above, then eligible for
//     COB scholarship and message is printed.
//     Otherwise "not eligible" message is printed.
//
//
// Problem Solution Design Steps:
// ------------------------------
//
//      Data structures:
//      ----------------
//
//      colleg:   String
//      GPA:      float
//
//      Algorithm:
//      ----------
//
//      1. Prompt for college
//      2. Input: college
//      3. Prompt for GPA
//      4. Input GPA
//      5. If not college CENG or COB
//         Print error message
//      6. else if GPA outside 0.0-4.0 range
//         Print error message
//      7. else
//         A. if college is CENG and GPA >= 3.2
//            Print "eligible for a CENG scholarship"
//         B. else if college is COB and GPA >= 3.3
//            Print "eligible for a CENG scholarship"
//         C. else
//            Print "not eligible for a scholarship"
