CMIS 102 Homework 3
Program Description - This program will allow a user to input their name and final grades from their courses and calculate their GPA accordingky. The amount of students as well as the amount of classes each student is taking, are undetermined.
Analysis – First I need to declare A, B, C, D, F and GPA as integers.
A = 4, B = 3, C = 2, D = 1, F = 0.
Each of these numbers will be floated
The program will ask for the name of the user
User Name: Stephen
The program will then ask for the grades.
Grades Entered: A,A,D
The letters corresponding to the integers will be summed ex. A+A+D = 4+4+1 = 9
The program will then divide the sum of the integers by the amount entered.
9/3 = 3.0 = GPA
The program will print the students name and their GPA
Name: Stephen GPA = 3.0

Pseudocode-
//Purpose: This program will allow students to input their name and grades to determine a GPA value
//Developer: Joe Metz
//GPA Calculator
//Variable Definition
Input=STUDENT_NAME, GRADES
Floats=GPA
Integers= NUM_OF_CLASSES, GRADE_POINTS,A,B,C,D,F
//Declare Integer Values
GRADE_POINTS= A=4, B=3, C=2, D=1, F=0
//Initiate Student Loop
For (students=0; students<10; students++)
Print “Enter Student Name”
User Input Student Name
//Reset sum to 0.0
Sum=0.0
Print “Input Grades”
User Input Grades
//Calculate Grade_Points
SUM=SUM_OF_GRADEPOINTS
//Calculate GPA
GPA=SUM/NUM_OF_CLASSES
Print “The GPA for “STUDENT_NAME” is “GPA”
