WHAT IS A UNION A union, is a collection of variables of different types, just like a structure. However, with unions, you can only store information in one field at any one time. You can picture a union as like a chunk of memory that is used to store variables of different types. Once a new...
Two of my friends faced a problem with writing a program which finds the LCM(Lowest Common Multiple)/GCD(Greatest Common Divisor) of two positive integers, so I helped them out by writing two functions for each. I thought many others might be having the same problem. So here are the functions:...

Refer to the recent articles on Understanding File Handling Functions in C & Understanding Advance File Handling Functions in C C communicates with files using a new datatype called a file pointer. This type is defined within stdio.h, and written as FILE *. A file pointer called output_file is...
The article discusses about all the number formats viz Binary, Decimal, Octal, Hex and BCD (Binary coded decimal) and conversion from Decimal to Binary, Octal and Hex and also the reverse conversion. Binary A numbering system based on 2 in which 0 and 1 are the only available digits. ...

I recently faced a problem regarding these 2 Escape Sequences. So, I thought I should share the difference between these two to clarify to all who may hay have confusion like me. Thanks to Shabbir too...... The Difference There are a few characters which can indicate a new line. The usual...
I thought of sharing the code snippet. It just does the basic operations like inserting a node at the end of the linked list and deletion of any particular node in the linked list. The deletion of a node in linked list is based on the data of the node and not on the index at which data is located....
