• Operators in C++ can be classified into 6 types: 1. Arithmetic Operators 2. Assignment Operators 3. Relational Operators 4. Logical Operators 5. Compound Operators 6. Increment & Decrement Operators
• Operator : +

  Operation : addition
• Operator : - Operation : substraction
• Operator : * Operation : multiplication
• Operator : / Operation : division
• Operator : % Operation : Modula operation
• Operator : a = b; Equivalent to : a=b;
• Operator : a += b; Equivalent to : a = a + b;
• Operator : a -= b; Equivalent to : a = a - b;
• Operator : a *= b; Equivalent to : a = a * b;
• Operator : a /= b; Equivalent to : a = a / b;
• Operator : a %= b; Equivalent to : a = a % b;
• Operator : ==

  Meaning : equal to

  Example 3 == 5 is 0
• Operator : !=

  Meaning : not equal to

  Example : 3 != 5 is 1
• Operator : > Meaning : greater than Example : 3 > 5 is 0
• Operator : < Meaning : less than Example : 3 < 5 is 1
• Operator : >= Meaning : greater than or equal to Example : 3 >= 5 is 0
• Operator : <= Meaning : less than or equal to Example : 3 <= 5 is 1
• Operator : && Meaning : true if all the operands are true

  Example : expression 1 && expression 2 is 1
• Operator : || Meaning : true if at least one operands is true

  Example : expression 1 || expression 2 is 0
• Operator : ! Meaning : true if only operands is false

  Example : !expression is 1
• Operator : price *= units + 1

  Equivalent : price = price * (units+1)
• Every statement must end with semicolon ( ; )

  Terminate with return 0;
• 0 is false

  1 is true
• Arithmetic Operators

  1. Addition , +
  2. Substraction, -
  3. Multiplication, *
  4. Division, /
  5. Modula Operation, %
• Assignment Operators

  1. a = b;
  2. a += b; additional
  3. a -= b; substraction
  4. a *= b; multiplication
  5. a /= b; division
  6. a %= b; Modula operation
• Relational Operators

  1. Equal to, ==
  2. Not equal to, !=
  3. Greater than, >
  4. Less than, <
  5. Greater than or Equal to, >=
  6. Less than or Equal to, <=
• Logical operators

  1. Logical AND, &&
  2. Logical OR, ||
  3. Logical NOT, !
