/* Passing Efficiency Calculator

Write a C program that calculates passer rating for NCAA quarterbacks.

The Inputs:
	Pass Attempts - ATT
	Pass Yards - YDS
	Completions - COMP
	Passing Touchdowns - TDS
	Interceptions - INTS

The output is the passer rating, also called passing efficiency.

All inputs should be whole numbers.
The output should be truncated at 2 places after the decimal point.

The following is the relevant equation:
  Passer Rating = ((8.4*YDS)+(330*TDS)+(100*COMP)-(200*INT))/ATT
 
The formula calculation must be performed inside a function that 
return the passer rating to the main function, which prints it.
 
The sample run below uses stats from ISU quarterback
Steele Jantz' 2011 season.
 
============= START OF SAMPLE RUN =======================
Enter Pass Attempts: 259
Enter Passing Yards: 1519
Enter Touchdowns: 10
Enter Completions: 138
Enter Interceptions: 11
This quarterback has a passer rating of 106.79
=============  END OF SAMPLE RUN  =======================
