Void In Dev C++
Functions in c programming with examples: A function is a block of statements, which is used to perform a specific task. Types: predefined and user-defined. Feb 09, 2016 Just need a little help for this one. I'm beginning to learn how to use functions, and I need for this one to output a straight line based on how long the user wants it, and what fill character they want. However using gotoxy funxtion is quiet difficult in devc because there is no such header file present in dev c to use gotoxy function what we have to all do is that we have to create the function for positioning cursor in devc. Dec 03, 2015 Void is a very interesting concept in c. Void in general means empty.so you can fill any thing inside. Usually int variables can store only int value. Similarly char, float, double can store only values of their type.now concider you don't know what kind of data u. Nov 29, 2016 Download Dev-C for free. A free, portable, fast and simple C/C IDE.

- C++ Basics
- C: Function Pointers We've previously talked about pointers to data structures and class objects, however in C we can also have pointers to functions. These pointers behave a little bit differently that the other pointers we've come across so far, but by the end of this tutorial you should know how to use function pointers, as well as knowing the basics of what you can.
- That keyword was available when somebody needed a point to an arbitrary type, thus void. as the idiom in C. It actually works pretty well if you interpret void as an empty structure. A void. pointer is the address of a place where that empty structure has been put. Casts from void. to T. for other types T, also work out with this perspective.

An if statement can be followed by an optional else statement, which executes when the boolean expression is false.
Void In C Code
Syntax
The syntax of an if..else statement in C++ is −
If the boolean expression evaluates to true, then the if block of code will be executed, otherwise else block of code will be executed.

Example
When the above code is compiled and executed, it produces the following result −
if..else if..else Statement
An if statement can be followed by an optional else if..else statement, which is very usefull to test various conditions using single if..else if statement.
When using if , else if , else statements there are few points to keep in mind.
An if can have zero or one else's and it must come after any else if's.
An if can have zero to many else if's and they must come before the else.
Once an else if succeeds, none of he remaining else if's or else's will be tested.

C++ Void Function
Example
When the above code is compiled and executed, it produces the following result −
-->When used as a function return type, the void keyword specifies that the function does not return a value. When used for a function's parameter list, void specifies that the function takes no parameters. When used in the declaration of a pointer, void specifies that the pointer is 'universal.'
If a pointer's type is void*, the pointer can point to any variable that is not declared with the const or volatile keyword. A void* pointer cannot be dereferenced unless it is cast to another type. A void* pointer can be converted into any other type of data pointer.
A void pointer can point to a function, but not to a class member in C++.
