[RESOLVED] I am trying to understand why I am getting wrong output for my program.

[Bankaijoey]

For my average output I am getting 008914D8 and for my letter grade output I am getting 0089121C. Any help will be great. Thank You.

// This program will input an undetermined number of student names
// and a number of grades for each student. The number of grades is 
// given by the user. The grades are stored in an array.
// Two functions are called for each student. 
// One function will give the numeric average of their grades.
// The other function will give a letter grade to that average. 
// Grades are assigned on a 10 point spread.  
// 90-100 A   80- 89 B  70-79 C   60-69 D   Below 60 F

cout << findGradeAvg;

You are not calling the function findGradeAvg with the required parameters.
