I'm having an issue with invalid inputs, such as when someone inputs a letter when asked for "How much do you want to bet" , it would go ahead an run the problem indefinitely and print out really high numbers or really negative numbers as my balance.
Along those lines similar problem occurs when asked to hit or stay, but it just doesn't run indefinitely, it just prints out those extreme numbers.
Pretty much I'm having issues controlling invalid inputs, it seems as though my if else statements are being bypassed?

Read all inputs as strings. Then test to see if all characters are digits and if so, convert to a number and continue. Otherwise, process an error.

I searched around and it seems as though reading all input as string then converting it requires programming a bit beyond my current knowledge. Is there another way of approaching this?

If it's beyond your current knowledge, put the task in the shelf for a few weeks and come back to it. You will probably have enough knowledge by then to start tackling the job.

Or search the forums. This has been answered a lot!

hey waltp, thanks for putting up with me, so I fixed one of the problems regarding having a $0 balance and the game would continue by using

bool exitswitch = false; // on the outside of the switch statement
exitswitch = true; // within the loop cased inside the switch
if(exitswitch == true) break; // in the switch

now I'm not sure if that was a good way of doing it, but it works....
as for inputing a letter instead of a number, causing the program to loop endlessly, I'm guessing were back to conversions?

nevermind, I was able to fix the endless loop by adding a

cin.clear();
cin.ignore();

in my else statement.

also fixed invalid input for HIT or Stay by adding an extra if else statement to check for an error value assigned if an invalid input was given.

Great!!

Yep...
