To answer this question, you probably need to know how to use functions and references along with basic input/output such as cin and cout, and other simple stuff such as comparison operators (to calculate the minimum of some numbers) and arithmetic operators (to calculate the average of some numbers).
Write a program to calculate the average of three test scores. The program must use the following function prototypes (do not change them):
int getScores ( int &, int &, int & );
Function prompts the user to enter 4 test scores.
int findLowest ( int, int, int, int );
Function identifies the lowest score
void calcAvg ( float &, int, int, int );
Function calculates the average of the 3 highest scores.
void displayAvg ( float );
Display the average with 1 decimal position.
All functions will be called by main.
