Need Help Please!!!

Hp of Legend (16)
I have to create a program that reads data from a file and calculates the GPA average for female and male students.

The program must contain these functions, openResults, initialize, sumGrades, averageGrades, and printResults.

The problem I"m having is that when I run the program when finding the female's GPA all it does is output the added GPA of the male students.

This is the data that I'm using
M 3.45
M 2.56
F 1.98
M 4.00
F 3.00
M 3.89
F 2.99
M 3.76
M 2.89
F 1.88
M 2.67

Here is what I have so far...

Any help would be most appreciated and Thank You.
