//SUMMARY
/*This program takes as input the user's scores on 6 programs and 2 exams.
It then calculates the weighted total grade for the user. Note the item
weights are exactly as given in this term's course syllabus. You will
be able to use this program to calculate your own final weighted total. */
//INPUT
//All input is interactive. The user inputs the scores as integer values.
//OUTPUT
/* The program prints an output title, echoprints the user's input in
a readable fashion, and the prints out the calculated final result. */
//ASSUMPTIONS
/* We assume that all input data is valid and correctly entered by the user.
The program is therefore not guaranteed to work correctly if bad data
is entered. */

//SUMMARY
/*This program uses multiple functions to take as input the users bet, and then takes in the users
guesses,
whilst prompting the user if the guess was too high or too low. If the user wins, the program calculates
the new amount of money by dividing the bet by the number of guesses it took. If the user loses, the
new
amount would be reflected by taking the entire bet amount from the amount of money the user has.
Afterwards,
the program will tell these monetary values, calculate and tell the percentage of games won, and ask the
user
if they would like to play again.*/
//INPUT
/*All input is interactive. The user inputs a bet and multiple guesses as integer values.
A char value is taken as a response is the user would like to play again or not.*/
//OUTPUT
/* The program prints an output title and summary, as well as prompts for the users bet, guesses
and the calculated totals. It also prompts the user if there was an error with any input for the initial bet.
*/
//ASSUMPTIONS
/* We assume that input data can be invalid and incorrectly entered by the user.
If bad input data is entered, the program will check for errors and go through
proper steps to functon normally.*/
