thanks tim

I hope you're not asking me because I can barely bash script and know nothing about any real languages

:( Well if you were wondering..

The reason to use foo(void) in C and not in C++ is because C++ is stricter about how functions are called.In C, if you leave out the (void) part, you can call the function with any amount of arguments

int foo();
// defined somewhere

// these are all valid, will not issue compiler errors
foo(1, 2, 3, 4, 5);
foo();
foo("hello", 1.2345, 1);

If you did declare it with

int foo(void)l

then all those would generate compiler errors. In C++

int foo();

means the same as

 int foo(void)

in C C++ will give out errors if you try and call the function with arguments
