# What Is & Operator In C?

The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. The | (bitwise OR) in C or C++ takes two numbers as operands and does OR on every bit of two numbers. The result of OR is 1 if any of the two bits is 1.

### How do you calculate operations?

There are three formulas to calculate income from operations:

1. Operating income = Total Revenue – Direct Costs – Indirect Costs. OR.
2. Operating income = Gross Profit – Operating Expenses – Depreciation – Amortization. OR.
3. Operating income = Net Earnings + Interest Expense + Taxes. Sample Calculation.

### What is the use of bitwise operator?

A bitwise operator is an operator used to perform bitwise operations on bit patterns or binary numerals that involve the manipulation of individual bits. Bitwise operators are used in: Communication stacks where the individual bits in the header attached to the data signify important information.

### How does Bitwise and operator work?

The bitwise AND operator ( & ) compares each bit of the first operand to the corresponding bit of the second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. Both operands to the bitwise AND operator must have integral types.

### What is the result of the Bitwise operation 1?

The result of the bitwise Exclusive-OR operation is 1 if only one of the expression has the value as 1; otherwise, the result is always 0. As we can see, two variables are compared bit by bit.

### What is the Bitwise operator used to set a particular bit value to 1 * & and/or exclusive or operator?

The bitwise-AND operator compares each bit of its first operand to the corresponding bit of its second operand. If both bits are 1, the corresponding result bit is set to 1.

### What is the purpose of XOR?

It is used in simple digital addition circuits which calculate the sum and carry of two (half-adder) or three (full-adder) bit numbers. XOR gates are also used to determine the parity of a binary number, i.e., if the total number of 1's in the number is odd or even.

### How do you calculate Bitwise Operators?

The bitwise operators are the operators used to perform the operations on the data at the bit-level.

### What is the difference between declaration and definition?

Whereas, Definition of a variable says where the variable gets stored. i.e., memory for the variable is allocated during the definition of the variable.

Difference between Definition and Declaration.

DeclarationDefinition
A variable or a function can be declared any number of timesA variable or a function can be defined only once

### What is difference between declaring a variable and defining a variable?

Difference Between Definition and Declaration

It aims at determining the overall values stored in a class, a function, or a variable. It aims at specifying the name of any given class, function, variable, etc. Definition allocates memory to an entity. A declaration does not allocate memory to the entities.

### What is the bitwise operator used set a particular bit to zero o *?

Which of the following bitwise operations will you use to set a particular bit to 0? Explanation: 1 AND 0 = 0, 0 AND 0 = 0, any bit AND with 0 gives 0.

### What is & operator in C?

The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. The | (bitwise OR) in C or C++ takes two numbers as operands and does OR on every bit of two numbers. The result of OR is 1 if any of the two bits is 1.

### What is variable definition and declaration?

Answer: Variable declaration tells the compiler about data type and size of the variable. Whereas, variable definition allocates memory to the variable. Variable can be declared many times in a program. But, definition can happen only one time for a variable in a program.

### What is the bitwise operator used to set a particular bit?

Explanation: Bitwise operator | can be used to “set” a particular bit while bitwise operator & can be used to “reset” a particular bit.

### What is the output of bitwise OR operation on?

The output of bitwise OR is 1 if at least one corresponding bit of two operands is 1. In C Programming, bitwise OR operator is denoted by |.

### What is meant by Bitwise operation?

Bitwise operators are characters that represent actions to be performed on single bits. A bitwise operation operates on two-bit patterns of equal lengths by positionally matching their individual bits: A logical AND (&) of each bit pair results in a 1 if the first bit is 1 AND the second bit is 1.

### What is the result of 16 >> 2?

. Is correct. 16 >>> 2 = 4.

### How is XOR value calculated?

To find each bit of XOR just calculate number of 1's in the corresponding bits. If it is even or zero then that XOR'ed bit is 0. If it is odd then that XOR'ed bit is 1.

### Why XOR is called exclusive or?

When both inputs are equal, either are 1 or both are 0, the output will be logical 0. This is the reason an XOR gate is also called an anti-coincidence gate or inequality detector. This gate is called XOR or exclusive OR gate because its output is only 1 when its input is exclusively 1.
