Prerequisite – Operators in C In C, logical operators are used to perform logical operations on expressions that evaluate to either true (nonzero) or false (zero). They are typically used in conditional statements and loops to make decisions based on whether certain conditions are met or not. Types of Logical Operators in C: There are three logical operators… Read More »
Prerequisite – Operators in C In C, assignment operators are used to assign a value to a variable. They combine the assignment operation (=) with an arithmetic, bitwise, or other operation. Here are the assignment operators in C: List of Assignment Operators in C: Operator Example Equivalent to = a = b a = b += a +=… Read More »
Relational operators in C are used for comparing values and determining whether they are equal, not equal, greater than, less than, greater than or equal to, or less than or equal to each other. Here is a list of relational operators in C: 1. Equal to (==): Returns true if the two operands are equal, false otherwise. In… Read More »
Arithmetic operators in C are used for performing mathematical operations, such as addition, subtraction, multiplication, and division. Here is a list of arithmetic operators in C: 1. Addition (+): Adds two operands together. 2. Subtraction (-): Subtracts one operand from another. 3. Multiplication (*): Multiplies two operands. 4. Division (/): Divides one operand by another. Note that if… Read More »
C operators are symbols or keywords that are used to perform different operations on one or more values. In C programming language, operators are classified into several categories, including: 1. Arithmetic Operators: These operators are used to perform basic arithmetic operations such as addition, subtraction, multiplication, division, and modulus (%). Here is a list of all arithmetic operators… Read More »
In C, a void pointer, also known as a generic pointer, is a pointer that can point to any type of data. The void type is a special type that represents the absence of any type. Therefore, a void pointer is a pointer that does not have any type associated with it. Declaring Void Pointer in C:: Here… Read More »
In C, a double pointer is a variable that stores the address of a pointer. It is also known as a pointer-to-pointer. Double pointers are useful when you need to modify the value of a pointer itself, not just the value it points to. Declaring Double Pointer in C: Here is an example of how to declare a… Read More »
In C programming language, a function pointer is a variable that holds the address of a function. It allows us to pass functions as arguments to other functions, store functions in arrays or structures, and call functions indirectly. Declaring Function Pointer in C: To declare a function pointer, you need to specify the return type and the parameter… Read More »
In C programming language, a null pointer is a pointer that has a value of “null”, or “0”. A null pointer is a pointer that does not point to any memory location. It is often used to indicate that a pointer is not currently pointing to a valid memory location. Uses of NULL Pointer in C : Null… Read More »
Pointers are a fundamental concept in the C programming language, which allow direct access to memory locations. A pointer is a variable that holds a memory address, which points to the location of a value in memory. Pointers are used to pass information between functions, dynamically allocate memory, and access data structures. In C, pointers are declared using… Read More »
