Main function is calling the other functions of he program and compiler gets this direction while Compiling the code. If it does not find main function then it will also not find the other functions in the code. So, main is required in C program.

Because the languages have defined that main() be their entry point. Suppose they left it ambiguous, then you’d have to specify somewhere that method {x} is your starting point which is the same as having a main program which could call that method {x}.

Would you rather write code that just starts up some random function? Or do you have a better alternative? If not, then there is no point to this question? read less

main is an entry point (like a main door) for your code written in C / C++ /Java/C# . So without main the code cannot be executed.
