A function can take a pointer to any data type, as argument and can return a pointer to any data type. For example, the function definition double *maxp(double *xp, double *yp) { return *xp >= *yp ? x; } specifies that the function maxp() return a pointer to a double variable...

As the definition of pointer says that its a special variable that can store the address of an other variable. Then the other variable can very well be a pointer. This means that its perfectly legal for a pointer to be pointing to another pointer. Lets suppose we have a pointer ‘p1’ ...
Pointers in C has always been a complex concept to understand for newbies. In this article, we will explain the difference between constant pointer, pointer to constant and constant pointer to constant. This article is part of the ongoing series on C pointers:part 1,part 2, part 3 (this a...

In the C Programming Language, the #define directiveallows the definition of macros within your source code. These macro definitions allow constant values to be declared for use throughout your code. ... You generally use this syntax when creating constants that represent numbers, strings or expre...
Actually, the above definition of "lvalue" is somewhat modified for C. According to K&R II (page 197): [1] "Anobjectis a named region of storage; anlvalueis an expression referring to an object." However, at this point, the definition originally cited above is sufficient. As we become...
In below programs, we saw that the member functions of the objects can manipulate data members directly without using the member access operator. Consider the following member function definition in a class rectangle. 1 2 3 4 void rectangle::setdata(int i,int j) { l = i; b = j; } We...
