symbolic code

[kassik]

Cant figure out how to write a code for add or subtracting symbols
for example:
alpha+alpha=2alpha

any help is appreciated.

Have you tried writing it the other way around (reverse the order)?

int a = 3;
int b = 4;
int c = a + b; //c is now 7

I just want to get my data in a symbolic way not by an integer.
i am trying to write a code with symbolic calculation and I don't like to define a special integer number as a symbol.

thanks

You mean like this?
#define C (a+b)

or in order to search what would be my key word ?
