C is a powerful general purpose programming language. It can be used to develop software like operating systems, databases, compilers, and so on. C programming is an excellent language to learn to program for beginners.
Our C tutorials will guide you to learn C programming one step at a time.
In C programming, a string is a sequence of characters terminated with a null character \0. For examples: char str[] = “Topperworld\0”; When the compiler encounters a sequence of characters enclosed in the double quotation marks, it appends a null character \0 at the end by default. Declaring a String in C : A String …
In C programming language, we can have a concept of Pointer to a function known as function pointer in C. In this tutorial, we will learn how to declare a function pointer and how to call a function using this pointer. To understand this concept, you should have the basic knowledge of Functions and Pointers …
A pointer is a variable pointing to the address of another variable. It is declared along with an asterisk symbol (*). A pointer can also be used to refer to another pointer function. A pointer can be incremented/decremented, i.e., to point to the next/ previous memory location. The purpose of pointer is to save memory …

The C preprocessor is a micro processor that is used by compiler to transform your code before compilation. It is called micro preprocessor because it allows us to add macros.All preprocessor directives starts with hash # symbol. Some advantages of using preprocessor are- Readability of the program is increased. Makes the program portable and efficient. …
What is File Handling in C? A file is nothing more than a method of permanently storing data in the form of a series of bytes on a disc. The contents of a file are not as volatile as the memory of a C compiler. When declaring a file in C, the structure pointer of …
The structure is a user-defined data structure that is used to bind two or more data types or data structures together. Like for storing details of a student, we can create a structure for student that has the following data types: character array for storing name, an integer for storing roll number, and a character …
Dynamic memory allocation is the process of allocation of memory space at the run time. We use the concept of dynamic memory allocation to reduce the wastage of memory, and it is the optimal way of memory allocation. Dynamic memory is managed and served with pointers that point to the newly allocated memory space in …
If you want to pass a single-dimension array as an argument in a function, you would have to declare a formal parameter in one of following three ways and all three declaration methods produce similar results because each tells the compiler that an integer pointer is going to be received. Similarly, you can pass multi-dimensional …
Operators are symbols that help in performing operations of mathematical and logical nature.The classification of C operators are as follows Arithmetic Relational Logical Bitwise Assignment Conditional Uses of Operators in C:- The operators basically serve as symbols that operate on any value or variable. We use it for performing various operations- such as logical, arithmetic, …
