C++ Operators

Operators are symbols which can function as logical and mathematical operation in C++ program.

An operator is a symbol that represents and tells the compiler to perform some specific mathematical or logical manipulations. The value that the operator operates is known as operands.

C++ operators

Below are Operators which are used in the C++ program:

  • Arithmetic operators
  • Assignment operators
  • Relational operators
  • Logical operators
  • Bit wise operators
  • Conditional operators (ternary operators)
  • Increment/decrement operators
  • Special operators
Operators Description Examples
Arithmetic operators (+,-,*,%,/) Addition of two number A=10, B=20, C=A+B, C=30
Assignment operators (=, ^=, -=, *=, /=, %=, &=, +=) Assigns values from right side operands to left side operand x=10, y=20, the value of x+y assign to z
Relational operators (>, <, >=, <=, ==, != ) Check the two values are equal or not. If yes, then the condition becomes true. (A == B) and (10==10) is true.
Logical operators (&& , ||, !) If (A && B) are non-zero, then the condition becomes true. int a=10, b=2; if(a==10&&b==2) is true
Bitwise operators (&, |, ~, ^, <<, >>) [& – Bitwise AND, | – Bitwise OR, ~ – Bitwise NOT, ^ – XOR, << – Left Shift, >> – Right Shift] int a=10, b=14; if(a& b) is true
Conditional operators (ternary operators)(?:) (Condition? true_value: false_value); (A > 100 ? 0 : 1);
Increment/decrement operators(++, --) Pre/Post-increment, Pre/Post-decrement int i=10; i++;
Special operators [&, *, Sizeof ()] & (address of the variable), *(pointer to a variable), Sizeof () (size of the variable) int a=10; sizeof (a) integer, will return 4.
