Simple Question about editing .exe

[BashVendetta]

Hi,

 

Just a small question, what do you guys use to edit/add these .exe files?

 

I have been using IDA and also Olly but someone mentioned something about being good at C++? I am confused now considering IDA and Olly dont require this....

 

I noticed as well people adding new commands that were not there in the first instance again interested where this was going.

 

Thanks
