Arithmetic and Logical operators in C++

This code snippet demonstrates various operators in C++:

• Arithmetic operators: Multiplication, Division, Addition, Subtraction, Modulus

• Increment and Decrement operators

• Assignment operator

• Comparison operators: Equal, Greater, Less, Not Equal, Greater or Equal, Less or Equal

• Bitwise operators: AND, OR, XOR, NOT

• Logical operators: AND, OR

It also includes output statements to display the results of these operations.

Explanation

The provided C++ code is a simple demonstration of various operators in C++. It includes arithmetic, assignment, comparison, logical, and bitwise operators.

The code begins by declaring two integer variables, num1 and num2, with values 10 and 5 respectively.

int num1 = 10;
int num2 = 5;

The arithmetic operators are then demonstrated. These include multiplication (*), division (/), addition (+), subtraction (-), and modulus (%). The results of these operations are printed to the console.

cout << "Multiplication: " << num1 * num2 << endl;
cout << "Division: " << num1 / num2 << endl;

The increment (++) and decrement (–) operators are demonstrated next. The variable result is incremented and decremented, and the results are printed to the console.

result++;
cout << "After increment: " << result << endl;

The assignment operator (=) is used to assign the value of num1 to result.

result = num1;
cout << "Assignment: " << result << endl;

The comparison operators (==, >, <, !=, >=, <=) are used to compare num1 and num2. The results of these comparisons are printed to the console.

if (num1 == num2) {
    cout << "Equal" << endl;
}

The bitwise operators (&, |, ^, ~) are used to perform bitwise operations on num1 and num2. The results of these operations are printed to the console.

cout << "Bitwise AND: " << (num1 & num2) << endl;

Finally, the logical operators (&&, ||) are used to perform logical operations on num1 and num2. The results of these operations are printed to the console.

cout << "Logical AND: " << (num1 && num2) << endl;

In summary, this code provides a comprehensive demonstration of the various operators available in C++.
