The logical extension of the concept ofpassing a pointer to a functionleads to passing aUnionpointer, i.e., the pointer of amulti-dimensional array, passing the pointer of aself-referential structure, etc., all these have important uses in different application areas such as complex data struct...

In this tutorial, you will learn how to pass a pointer to a function as an argument. To understand this concept you must have a basic idea ofPointersandfunctions in C programming. Just like any other argument, pointers can also be passed to a function as an argument. Lets take an exampl...
when passing the pointer 'a', the error is occurred, even then the function seems like to initializing the pointer. but , when passing parameter by pointer, the address which the pointer point to is been passed.so, when a pointer is not been initialized , the address which the pointer po...
Instead of passing an array of characters, we will pass a string pointer. That way, the string’s address will be passed down to the function, using that address string will be fetched out and displayed on the console. For declaring the pointer, we need to type * with any variable name...

When you define 'c' and 'd' as pointers in main function you will pass them to function like this:pointerIntro(first, second, c, d);because they are already pointers and you don't need to send their reference, you just send them. ...
