Srand Time Null Dev C Calculator
Well ehm hey,i am new to the forums here and generally in c language.
I started studying from kernighan and ritchie book and at last after i tried some mini programs testing them on dev c++(i will later use other programs,i choosed that for the time being),i tried to make a small program in order to test myself the rand and srand functions.
I wrote this code,(i suppose as a beginner that i didn't make any huge mistakes)
and the debugger pops up with that:
ISO C++ forbids declaration of `main' with no type
What is this supposed to be?
Thanks in advance
