Assignment Operators in C ++

Certainly, let's explore assignment operators in C++.

Assignment Operators

In C++, assignment operators are used to assign values to variables. The most basic assignment operator is the = operator.

Basic Assignment (=)

 * This operator assigns the value on the right-hand side to the variable on the left-hand side.

   int x = 10; 

// Assigns the value 10 to the integer variable 'x'

Compound Assignment Operators

C++ provides several compound assignment operators that combine an arithmetic operation with the assignment. These operators make the code more concise and efficient.

 * +=: Adds the value on the right-hand side to the variable on the left-hand side and assigns the result to the variable.

   x += 5; // Equivalent to x = x + 5; 

 * -=: Subtracts the value on the right-hand side from the variable on the left-hand side and assigns the result to the variable.

   x -= 3; // Equivalent to x = x - 3;

 * *=: Multiplies the variable on the left-hand side by the value on the right-hand side and assigns the result to the variable.

   x *= 2; // Equivalent to x = x * 2;

 * /=: Divides the variable on the left-hand side by the value on the right-hand side and assigns the result to the variable.

   x /= 4; // Equivalent to x = x / 4;

 * %=: Calculates the modulus (remainder) of the variable on the left-hand side with the value on the right-hand side and assigns the result to the variable.

   x %= 3; // Equivalent to x = x % 3;

 * <<=: Performs left shift on the variable on the left-hand side by the number of bits specified on the right-hand side and assigns the result to the variable.

 * >>=: Performs right shift on the variable on the left-hand side by the number of bits specified on the right-hand side and assigns the result to the variable.

 * &=: Performs bitwise AND operation between the variable on the left-hand side and the value on the right-hand side and assigns the result to the variable.

 * |=: Performs bitwise OR operation between the variable on the left-hand side and the value on the right-hand side and assigns the result to the variable.

 * ^=: Performs bitwise XOR operation between the variable on the left-hand side and the value on the right-hand side and assigns the result to the variable.

Example

#include <iostream>

int main() {

    int num = 10;

    num += 5;  // num is now 15

    num -= 3;  // num is now 12

    num *= 2;  // num is now 24

    num /= 4;  // num is now 6

    std::cout << "num: " << num << std::endl; 

    return 0;

}
