Seven Days coin toss Program

Akroncs (22)
I need to write a program that recreates the Battle of Seven Days using Coin flips, but I cant seem to get the score to increment correctly

/* Program created by to recreate the Battle of Seven Days with coin flips.
The user inputs their guess for each battle At the end of the nine battles the victor is determined and the actual history,
of the Battle of Seven Days will be shown. */

Please edit your code and use code tags - http://www.cplusplus.com/articles/jEywvCM9/

Sorry, I am new to posting, I did as you said.

@Akroncs

One big problem, is you set toss to equal "Tails" or "Heads", yet Guess can only be "T", "t", "H" or "h". Single characters. The two variables will never match. You could set the toss variable to a single character. That won't fully fix everything, but it's a start.
Akroncs (22)
I have to make it so It displays "Heads" when h or H is pressed, I am unsure on what else I can do for that to happen.
whitenite1 (1785)
@Akroncs

I fixed it up to display the "Heads" or "Tails", choices. But, since you're repeating a lot of the code, ie: for each battle, it would be wise to use as a function that gets called each time, instead. Will really make the program smaller, and easier to follow.

Thank you so much. I am new to coding and c++, this has been bugging me for awhile now.

If I were to use a loop to work for each battle without repeating code what would I do?

@Akroncs

Don't really have time at the present to create a the function right now, but will post a bit of it, later on in Thursday.
Akroncs (22)
That would be great!

There are a total of nine battles, each with their own name.

Here's using for loops and functions. The rest is up to you..
