Operators in C++

Operators in C++ are symbols that perform operations on variables and values. Here's a list of the commonly used operators, along with example programs:

• Arithmetic Operators
  + Addition
  - Subtraction
  * Multiplication
  / Division
  % Modulus
  ++ Increment
  -- Decrement

  
  // Example: Arithmetic Operators in C++
  #include <iostream>
  using namespace std;
  
  int main() {
      int a = 10, b = 3;
      cout << "a + b = " << a + b << endl;
      cout << "a - b = " << a - b << endl;
      cout << "a * b = " << a * b << endl;
      cout << "a / b = " << a / b << endl;
      cout << "a % b = " << a % b << endl;
      cout << "++a = " << ++a << endl;
      cout << "b-- = " << b-- << endl;
      return 0;
  }
                      

  Copy


• Relational Operators
  == Equal to
  != Not equal to
  > Greater than
  < Less than
  >= Greater than or equal to
  <= Less than or equal to

  
  // Example: Relational Operators in C++
  #include <iostream>
  using namespace std;
  
  int main() {
      int a = 5, b = 10;
      cout << "(a == b): " << (a == b) << endl;
      cout << "(a != b): " << (a != b) << endl;
      cout << "(a > b): " << (a > b) << endl;
      cout << "(a < b): " << (a < b) << endl;
      cout << "(a >= b): " << (a >= b) << endl;
      cout << "(a <= b): " << (a <= b) << endl;
      return 0;
  }
  

  Copy


• Logical Operators
  && Logical AND
  || Logical OR
  ! Logical NOT

  
   // Example: Logical Operators in C++
    
   #include <iostream>
   using namespace std;
  
  int main() {
      bool x = true, y = false;
      cout << "(x && y): " << (x && y) << endl;
      cout << "(x || y): " << (x || y) << endl;
      cout << "(!x): " << (!x) << endl;
      return 0;
  }
  

  Copy


• Bitwise Operators
  & AND
  | OR
  ^ XOR
  ~ NOT
  << Left shift
  >> Right shift

  
  // Example: Bitwise Operators in C++
  #include <iostream>
  using namespace std;
  
  int main() {
      int a = 5, b = 3;
      cout << "(a & b): " << (a & b) << endl;
      cout << "(a | b): " << (a | b) << endl;
      cout << "(a ^ b): " << (a ^ b) << endl;
      cout << "(~a): " << (~a) << endl;
      cout << "(a << 1): " << (a << 1) << endl;
      cout << "(b >> 1): " << (b >> 1) << endl;
      return 0;
  }
  

  Copy
