What does & mean in C language? The

& symbol has two meanings in C language. One represents the address operator, which is a unary operator. Its function is to obtain the memory address of a variable; while the other represents It is a bitwise operator and a binary operator. Its function is to AND the corresponding binary bits of two numbers.

C language operators

Arithmetic operators

are used for various numerical operations. There are seven types including addition ( ), subtraction (-), multiplication (*), division (/), remainder (or modular operation, %), autoincrement ( ), and autodecrement (--).

Relational operators

are used for comparison operations. It includes six types: greater than (>), less than (<), equal to (==), greater than or equal to (>=), less than or equal to (<=), and not equal to (!=).

Logical operators

are used for logical operations. Including and (&&), or (||), not (!).

Bit operation operator

The quantities involved in the operation are operated in binary bits. It includes six types: bitwise AND (&), bitwise OR (|), bitwise NOT (~), bitwise XOR (^), left shift (<<), and right shift (>>).

Assignment operator

is used for assignment operations, which are divided into simple assignment (=), compound arithmetic assignment (=,-=,*=,/=,%=) and compound bit operations There are eleven types of assignments (&=,|=,^=,>>=,<<=) in three categories.

Conditional operator

This is a ternary operator used for conditional evaluation (?:).

Comma operator

is used to combine several expressions into one expression (,).

Pointer operator

is used for two operations: content (*) and address (&).

The byte count operator

is used to calculate the number of bytes occupied by the data type (sizeof).

Special operators

include brackets (), subscripts [], members (→,.), etc.

What are constants in C language? Can you give an example? What are constants in C language? Can you give an example? Aug 28, 2023 pm 10:45 PM

A constant is also called a variable and once defined, its value does not change during the execution of the program. Therefore, we can declare a variable as a constant referencing a fixed value. It is also called text. Constants must be defined using the Const keyword. Syntax The syntax of constants used in C programming language is as follows - consttypeVariableName; (or) consttype*VariableName; Different types of constants The different types of constants used in C programming language are as follows: Integer constants - For example: 1,0,34, 4567 Floating point constants - Example: 0.0, 156.89, 23.456 Octal and Hexadecimal constants - Example: Hex: 0x2a, 0xaa..

Recursive program to find minimum and maximum elements of array in C++ Recursive program to find minimum and maximum elements of array in C++ Aug 31, 2023 pm 07:37 PM

We take the integer array Arr[] as input. The goal is to find the largest and smallest elements in an array using a recursive method. Since we are using recursion, we will iterate through the entire array until we reach length = 1 and then return A[0], which forms the base case. Otherwise, the current element is compared to the current minimum or maximum value and its value is updated recursively for subsequent elements. Let’s look at various input and output scenarios for this −Input −Arr={12,67,99,76,32}; Output −Maximum value in the array: 99 Explanation &mi

C++ program to print spiral pattern of numbers C++ program to print spiral pattern of numbers Sep 05, 2023 pm 06:25 PM

Displaying numbers in different formats is one of the basic coding problems of learning. Different coding concepts like conditional statements and loop statements. There are different programs in which we use special characters like asterisks to print triangles or squares. In this article, we will print numbers in spiral form, just like squares in C++. We take the number of rows n as input and start from the top left corner and move to the right, then down, then left, then up, then right again, and so on and so on. Spiral pattern with numbers 123456724252627282982340414243309223948494431102138474645321120373635343312191817161514
