This article provides a comprehensive overview of files in C programming language along with relevant examples. So far we have been using scanf and printf functions for reading and writing data to the console. This is fine as long as the data is less. However, many real world problems involve large amounts of data. […]
In this article you will learn about Unions in C language. First you will learn what is a Union, its syntax and then an example program demonstrating unions in C language. Unions have the same syntax as that of a structure since both of them are similar. However, there is a major difference between […]
This article provides a comprehensive overview of structures in C programming language along with example programs. We know that arrays can be used to represent a collection of elements of the same data type like int, float etc. They cannot be used to hold a collection of different types of elements. C supports […]
This article provides a comprehensive overview of pointers in C programming language along with useful example programs. A pointer is a derived data type in C. It is built from one of the fundamental data types available in C. Pointers contain memory addresses as their values. Since these memory addresses are the locations […]
This article provides a comprehensive overview of preprocessor directives in C programming language along with relevant examples. C provides many features like structures, unions and pointers. Another unique feature of the C language is the preprocessor. The C preprocessor provides several tools that are not present in other high-level languages. The programmer can […]
The storage classes in C specify the scope and lifetime of a variable in a C program. The scope (active) specifies in which parts of the program is the variable accessible and the lifetime (alive) specifies how long a variable is available in the memory so that the program will be able to access that […]
In this article we will learn about types of variables in C language. We will start with what is variable and then learn about types of variables like local variables and global variables. A variable is a memory location inside memory which is referred using a name. The value inside a variable changes throughout […]
This article provides a comprehensive overview of functions in C programming language along with easy to understand example programs. Until now, in all the C programs that we have written, the program consists of a main function and inside that we are writing the logic of the program. The disadvantage of this method is, […]
In this article we will learn about String Manipulation in C Programming. We will see different examples on manipulating strings. As we have already seen in the previously, a string is a collection of characters and strings are maintained as character arrays in C programs. The common operations or manipulations that can be […]
This article provides a comprehensive overview of arrays in C. First we will define what is an array and then see the syntax and example for creating and using arrays. Arrays In all the programs we have done until now, to store and operate on values we have used variables. But at a […]
