The description of the problem is
•Your program will have an input file that will consist of a list of contestants. The first line of the file is an integer that says how many contestants are in the file. Each line is for one contestant and each line in the file would have the following format (the name of the input file starsearch.dat):
Contestant Name(no spaces) score1 score2 score3 score4 score5

•Your program will have a function called string contestantName() that takes the file object as a reference parameter and reads the file for the name of the contestant on the current line and returns the name. This function should be called from main, once for each line of the file.
•The void getJudgeData() will read from the file and not from the user. This function will still use a reference parameter for the score, and it will read the next score from the file. This function will be called five times per contestant and is called from main once for each score.
•The void CalcScore() is used to calculate the score using the same formulation. However, this function will write the contestants name and score to an output file. The function will have 7 parameters instead of 5: output file (pass by reference), contestants' name, and the 5 judges scores.
•The output file will be a list of contestants, where each line has the following format (name the output file results.dat):
Contestant Name(no spaces) Final_Score

In summary, the program is the same as the original version with the additional features: input file, output file, and more than one contestant. This causes the changes in the functions for input and output. The findLowest and findHighest functions (one findes the lowest of the scores the other finds the highest) are still needed as stated in the original description.
My problem is trying to send the file by reference every time i do it sends a mixture of number s and letters instead of the data from the input file.

SAMPLE INPUT FILE

2
Jennifer 10 9 8 9.5 10
Michael 10 9 10 9 10


SAMPLE OUTPUT FILE

Jennifer 9.50
Michael 9.67

Your code is hard to read. That is the MAIN Problem.
Rewrite the function findhighest and findlowest.
This is an example.

double max(double a, double b){

	return a > b ? a:b;

}
double min(double a, double b){

	return a < b ? a:b;

}

Second instead of using if try to use case and switch.

I found the problem. The problem is the average. Please explain me how to calculate the average?
