The value of the expression clause is returned to the calling function. If the expression is omitted, the return value of the function is undefined. Constructors and destructors, and functions of type void,cannot specify an expression in the return statement. Functions of all other types must specify an expression in the return statement.

Hi everybody, I've recently upgraded my outdated Dev-C version to the new Orwell edition (version 5.3.0.4) and I noticed that if my program ends, this message shows up:- Process exited with return value 0 Press any key to continue.

C: Functions We've talked a little bit about functions in the past - they're pieces of code that can be executed on command. In fact we've been using functions right since the very start of this process, we just haven't really talked about them in depth - this is what this tutorial is all about.

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.
Syntax
The syntax of a for loop in C++ is −
Here is the flow of control in a for loop −
The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. You are not required to put a statement here, as long as a semicolon appears.
Next, the condition is evaluated. If it is true, the body of the loop is executed. If it is false, the body of the loop does not execute and flow of control jumps to the next statement just after the for loop.
After the body of the for loop executes, the flow of control jumps back up to the increment statement. This statement can be left blank, as long as a semicolon appears after the condition.
The condition is now evaluated again. If it is true, the loop executes and the process repeats itself (body of loop, then increment step, and then again condition). After the condition becomes false, the for loop terminates.
