Is it better to use C or C++?

For most people, C++ is the better choice. It has more features, more applications, and for most people, learning C++ is easier. C is still relevant, and learning to program in C can improve how you program in C++. Neither language is a bad choice, and both have realistic career applications.

Is compiler for C and C++ same?

The C runtime library used by your C compiler must also be compatible with the C++ compiler. C++ includes the standard C runtime library as a subset, although there are a few differences. Oracle Developer Studio C and C++ compilers use compatible headers, and use the same C runtime library. They are fully compatible.

What is the difference between Main() and int main() in C?

You have to use int main () otherwise . main () works but is confusing, in C the main function always returns an int, to specify exit status, so the correct syntax is int main (), but if you do not bother to set the exit status then main () is enough, but the good C books will always have int main ().

What is the difference between Foo() and main() in C++?

So, both foo (void) and foo () are same in C++ but not in C. The same is the case with ‘main’ function also. So, the preferred form to use is int main (void) if main is not taking any argument.

What is the main function in C programming?

The main function is the one where the program initiates its execution. All the other functions are called from the main function. But because of the feature “overloading” present in C programming, the main function can be called using different return types or parameters. We will discuss those types of main in this tutorial.

How does the main() function work in C++?

The main () function is like other functions. It also takes arguments, and returns some value. One point we have to keep in mind that the program starts executing from this main () function. So the operating system calls this function. When some value is returned from main (), it is returned to operating system.
