I would like to subtract win (an int value) from width in line 48 to correct formatting issues however it is not properly declared until after the loop runs through line 56.

Since you're not using the return result of coinFlip, and that result is a global anyway, why not make it return something useful.
1

3
4
5

char coinFlip()
{
    int random = (rand()%2)+1;
    if (random == 1)
        return 'H';
    else if(random == 2)
        return 'T'
}


Then

3
4
5
6
 
string result = "";
char toss;
do{
  toss = coinFlip();
  result += toss;
}while (toss == 'T');

You can do all that before you cout anything at all.
Then you can use result.length() to help you figure out what you need to do with your width variable.
