// Why does this source code not compile?
//
// First, examine the code and try to
// identify the problem without compiling it.
//
// If you cannot find the problem, compile
// the code and use the compiler's error
// message as a hint.
//
// If you still cannot find the problem,
// scroll down.

// Function declaration
int main();

// Function definition
int main() {
    std::cout << "Hello World!" << std::endl;

    return 0;
}


















































// The preprocessor directive
//
//     #include
//
// is misspelled as
//
//     #inclde
//
// Consequently, the <iostream> header is
// not included.
//
// You may notice additional error messages
// when you try to compile this code. Because
// <iostream> was not included, the compiler
// does not know the declarations of
// 'std::cout' or 'std::endl'.
