Recursion is a process in which a problem is defined in terms of itself. In ‘C’ it is possible to call a function from itself. Functions Read More »

Every repetitive problem can be implemented recursively or iteratively Recursion should be used when the problem is recursive in nature. Iteration should be used when the problem Read More »

To completely define a variable one needs to mention its type along with its storage class. In other words we can say not only variables have Read More »

Introduction A data structure is the way data is stored in the machine and the functions used to access that data. An easy way to Read More »

Arrays that we have considered up to now are one dimensional array, a single line of elements. Often data come naturally in the form of Read More »

The structure that contains another structure as its members is called a nested structure or a structure within a structure is called nested structure. The structure Read More »

Union is a collection of variables of different data types, in case of union information can only be stored In one field at any one time. Read More »

A pointer is a variable that contains the address of a variable. Pointers are much used in C, partly because they are sometimes the only way Read More »

In C, there is a strong relationship between pointers and arrays, strong enough that pointers and arrays should be discussed simultaneously. Any operation that can be Read More »
