Two 'main' functions in C/C++

Question

Can I write a program in C or in C++ with two main functions?

Answer 1

In some very special architecture, you can. This is the case of the Cell Processor where you have a main program for the main processor (64-bit PowerPC Processors Element called PPE) and one or many main program for the 8 different co-processor (32-bit Synergistic Processing Element called SPE).
