• Why main function main() without data type works on gcc compiler without Error? (Not related to tutorial video)

  I have question whenever we use int main() we have to return zero at the end and according to definition default value of main function is integer. Why it is not giving error in compilation in gcc compiler ? as it is mandatory to return zero at the end but it works properly. Even int main() also working without return(0).

• Program not compiling/running on TurboC

  I was trying to run the "Function with parameters" program displayed at the online video using TurboC(I typed a exactly same program shown in the video). But, it wasn't compiling/running and produced following error,Error#1 - Function should return a value,Error#2 - "c" is assigned a value that is never used.However, it was compiling/running successfully when the same program ran at minGW. Why was it not compiling/running at TurboC? Can i continue use TurboC?
