Now, if we get 2 values, the loop continues. If we don't get 2 values, either because we are at the end of the file or some other problem occurred (e.g., it sees a letter when it is trying to read in a number), then the loop will end ( will return a 0 in this case). A C program can be made easier to read and maintain by using references rather than pointers. A C function can return a reference in a similar way as it returns a pointer. When a function returns a reference, it returns an implicit pointer to its return value. This way, a function can be used on. Jan 01, 2013 Problem with new compiler Niels Meijer. Hi everybody, I've recently upgraded my outdated Dev-C version to the new Orwell edition (version 5.3.0.4) and I noticed that if my program ends, this message shows up:- Process exited with return value 0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. My program already said bye to the user, so this message is.

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. Cooking games download for free alpk. 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.

A C++ program can be made easier to read and maintain by using references rather than pointers. A C++ function can return a reference in a similar way as it returns a pointer.
C++ Return Object By Value
When a function returns a reference, it returns an implicit pointer to its return value. This way, a function can be used on the left side of an assignment statement. For example, consider this simple program −
When the above code is compiled together and executed, it produces the following result −

When returning a reference, be careful that the object being referred to does not go out of scope. So it is not legal to return a reference to local var. But you can always return a reference on a static variable.
