Hello, thanks for your answer Lawson,

but each time the program runs with a different formula i will have to
compile again the code, and i will have to build a new executable file
and run it, isn't it? i would prefer to run a single executable code
and not to jump from one to other (ie. using atexit from stdlib.h)
is it possible to compile/link just a function and call it from the initial
program (i mean, to add a function to the program while it is running in a way
that i do not need to exit from the initial program ) ?
Cheers,
Rafa
