I'm a beginner and just learning C++ and I'm a bit puzzled. I
understand the literal meaning of void return is to return nothing but
I don't understand the purpose by when a main function or a calling
function calls a function when the return type of the called function
returns void type. Why would you call it in the first place if it
adds no value to the main function? I thought the whole idea when you
call a function is to have a value returned to the main function or
calling function. But if the return value is void it's as if there is
literally no function to the called function. What am I missing
because the books I've been looking at don't explain this. Can
somebody give me an example of why void return is used?
