"Flowing off the end of a function is equivalent to a return with no returned value."

So when C++ introduced void as a return type, even for main

{
   int x;
   x = 42;
   return x; // ok
   return x + 1; // does not compile because x + 1 is an expression
   return(x + 1); // ok, the expression is evaluated by the compiler

You should NOT write these unnesseccary parentheses anymore!

The return statement is not a function call; just omit the parentheses.

ReTuRn("December");  // this is a function call
return("December");  // this is a return statement

You can write a C program on one line by removing those unnecessary end of line characters but that is not a good idea either.

return ((((0))));  // valid code, but stupid
return ((0));      // still stupid
return 0;          // that's the way to go

Would you suppose it's possible to understand computational science without the understanding of boolean logic?

In order to correct these distortions, we must identify them. In psychology, there's a concept known as cognitive behavioral therapy (CBT). In short, it's the process of identifying and correcting cognitive distortions.
