A virtual address is composed of the selector and offset. A near pointer doesn’t have explicit selector whereas far, and huge pointers have explicit selector. When you perform pointer arithmetic on the far […]

The Token is an identifier. It can be constant, keyword, string literal, etc. A token is the smallest individual unit in a program. C has the following tokens: Identifiers: Identifiers refer to the name of the […]

In case of dynamic memory allocation, memory is allocated at runtime and memory can be increased while executing the program. It is used in the linked list. The malloc() or calloc() function is required to […]

Accessing array elements: Pointers are used in traversing through an array of integers and strings. The string is an array of characters which is terminated by a null character ”. Dynamic memory allocation: […]

When a function calls itself, and this process is known as recursion. The function that calls itself is known as a recursive function. Recursive function comes in two phases: Winding phase Unwinding […]

C is called a mid-level programming language because it binds the low level and high -level programming language. We can use C language as a System programming to develop the operating system as well as an […]

C is known as a mother language because most of the compilers and JVMs are written in C language. Most of the languages which are developed after C language has borrowed heavily from it like C++, Python, Rust, […]

C is a mid-level and procedural programming language. The Procedural programming language is also known as the structured programming language is a technique in which large programs are broken down into smaller […]

In pass by refrence ,the callee recieves the address and makes a copy of the address of an argument of an argument into the formal parameter.callee function uses the address to acess the actual argument to do some […]

Enumeration,also known as enum in c, is a user defined data type.it consists of constant integrals or integers that have names assigned to them by the user. Because the integer values are named with enum in c,the […]

A preprocessor Is a software program that processes a source file before sending it to be complied .inclusion of header files,macro expansion ,conditional compilation,and line control are all possible with the preprocessor.

A pointer is a variable that stores or points to another variables address.The value of a variable is stored in a normal variable, whereas the address of a variable is stored in a pointer variable.In C ,a pointer […]

 C has characteristics of both assembly level I.e. low  level and higher level languages so as a result, C is  commonly called a middle level language. UsingC, a user can write an operating system as well as cr […]
