How can I a string from a . txt, reverse it and write it to another .txt in C++?

YAY!!!!

Yes, I finally figured it out, just had to add another condition inside if(i==1). I just added that the value of the array balance at the cell three cells away from the length of the string must be '.' . Thanks a lot WaltP, I really appreciate it.

Can you please post your full code?
