A multi-dimensional array is very useful in C language. We can replace nested switch case with a multidimensional array using the pointer to function. Using this technique, a function that has a hundred lines of code reduced dramatically. Previously I have worked on a POS (point of sale) application, in this application we have used […]

Using the switch case in C language, we can resolve complex conditional and branching operations. It reduces the comparison of integral value in a long if-else statement. The switch expression transfers the control to a specific part of the code which has written in the body of switch and case statements. The control transfer capability

A pointer is an amazing tool of c language we can do any task easily with the help of pointers. In my previous article, we have read that how to calculate the size of structure without using the sizeof() operator. In this article, I am calculating the sizeof array without using the sizeof() operator. Calculating

In C language, sizeof() operator is used to calculate the size of structure, variables, pointers or data types, data types could be pre-defined or user-defined. Using the sizeof() operator we can calculate the size of the structure straightforward to pass it as a parameter. But here I am interested in calculating the size of structure

Sometimes we need to perform arithmetic operations on pointers. But before using arithmetic operators with pointers we need to understand that we can not use each arithmetic operators with pointers. Pointer arithmetic is slightly different from arithmetic we normally use in our daily life. We also need to remember that we cannot use the

Pointers are a very important feature of the C/C++ programming language. You can not imagine C language without the pointers and you could not be a great C programmer without a good knowledge of the C pointers. In this blog post, you will learn about the pointers in C/C++; what are pointers, what are types

We can create both static and dynamic array in C. These arrays can be one dimensional or multiple dimensional. In statically allocated array problem is that we have to specify the size of the array before the compilation. So the problem is generated when we don’t know how much size of the array required ahead

The Internet is like a sea, it’s open a lot of opportunities for the new world. There is a lot of company, which depend on the internet. The Internet reduces the workload and time of the people. Now day’s people do not use the conventional way to send the information from one place to another

Before you start learning socket programming in C, you should basic knowledge of IP addresses, TCP, and UDP. In this article, I shall describe TCP/IP and write a socket program using the TCP/IP API. TCP (Transmission control protocol) A TCP (transmission control protocol) is a connection-oriented communication. It is an intermediate layer of the application

In this article, we will learn how to search an element in a linked-list. It is a very simple program that is generally asked in the interview. For example: Linked List: 13–>19–>20–>22–>11–>NULL Enter Element: 20 Result: Element Found Linked List: 14–>22–>10–>2–>7–>NULL Enter Element: 3 Result: Element Not Found Here we will see two methods
