Is there a default return value of C functions

I'm amazed that a file with the following lines of code is properly built and the linker generates an executable.

Except for main, I believed all functions had to include a proper return statement unless the return type was void.

int foo(){}
double bar(){}
int main(){}

What am I missing?

Function default argument value depending on argument name in C++ [duplicate]

When the function is called with no argument for the corresponding parameter, the default argument is evaluated. In a default argument, a parameter must not appear as a potentially evaluated expression. A function's parameters declared before a default argument are in scope and can obscure the namespace and class member name. It provides the following example: int h(int a, ...READ MORE

functions in c++ call by value and call by reference

Calling a function by value copies the argument and stores it in a local variable for use by the function, so the argument is unaffected if the value of the local variable changes. The argument is passed to the function as a reference rather than a copy, so if the function changes the value of the argument, the argument is also changed. The void change(int); function prototype informs the compiler that there is a function named change that takes a single int argument and returns void (i.e. nothing). Because there is no & with the argument, it is called by value. You have the line change(orig); later in your code, which actually calls the function with. Take a look at the output of ...READ MORE
