TURBO CALC 15000

This is a basic calculator compiled using GCC, but first written using Borland's Turbo C++ IDE 3.0, hence called turbo calc. It has 15 functions, hence 15000

PS: I am a rookie C++ programmer. I had learnt C in the begening of class 6(lol) but forgot it(lol again)

I made this because I just wanted to try something that looks usable. Please excuse my n00bishness

I regret the fact that we have only Turbo C++ in CBSE senior secondary scyllabus. Anjuta IDE and Dev-Cpp along with MinGW Developer Studio are forgotton. CBSE I suppose, is full fo linux haters.
