sum two numbers using ONE variable.

[DEP]

hi everyone,

can anyone tel me how to make a code in c/c++ which inputs two numbers from the user and add them by using ONE and only ONE variable in the entire program.

you could probably do it with strings or char* otherwise some ambiguous old school C/assembly way i'm sure. Would you consider using registers as a variable?

I would think another option would be to overload the '>>' operator...

what my overly-complicated suggestion not good enough?

Haha, of course it was good, I was merely offering another method. Personally I find pointers easier to use than overloading and re-including header files, or however you choose to implement, but the concept might be easier.

I'm actually just threatened by your posts - wanted to try to solidify my 'Moderator' status by padding the post count (not that I'm doing that here either....ooooh ! almost at 800!)

Since you know that there are two numbers....(and given you only use 1 var I assume you're not looking for robust code, and don't have to check validity of input etc (in my favourite pseudicide ):

int a=0;

a = a + getch();
a = a+ getch();

Now pray that the user only enters numbers less than 255.....Or you can probably find a better function to read inputs......
