Master the fundamentals of C programming. Learn syntax, pointers, and memory management to build a strong foundation in computer science.
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,
The two-dimensional array can be defined as an array of arrays.A two-dimensional array can be used to represent a matrix, a table or board games (Sudoku). The row and column positions are given as successive indices. When you declare a variable of such an array, use a pair of square brackets for each dimension. Declaration

Array in C programming language is a collection of fixed size data belongings to the same data type. An array is a data structure which can store a number of variables of same data type in sequence. These similar elements could be of type int, float, double, char etc. Properties of Array in C :
