Operators in C/C++
- 2. Operator & Operands âą Operators are the special kinds of symbols (or function like words (sizeof)) that are used to perform any specific task like mathematical and logical. âą Operands are the values (variables, symbols, functions) in which an operand acts upon.
- 3. Operators in C/C++ âą Arithmetic operators âą Relational operators âą Logical operators âą Bitwise operators âą Assignment operators âą Conditional operators âą Special operators
- 4. Arithmetic operators Operator Description + adds two operands - subtract second operands from first * multiply two operand / divide numerator by denominator % remainder of division ++ Increment operator - increases integer value by one -- Decrement operator - decreases integer value by one
- 5. Relational Operators Operator Description == Check if two operand are equal != Check if two operand are not equal. > Check if operand on the left is greater than operand on the right < Check operand on the left is smaller than right operand >= check left operand is greater than or equal to right operand <= Check if operand on left is smaller than or equal to right operand
- 6. Logical Operators Operator Description Example (a = true, b=false) && Logical AND (a && b) is false || Logical OR (a || b) is true ! Logical NOT (!a) is false
- 7. Bitwise operators Operator Description & Bitwise AND | Bitwise OR ^ Bitwise exclusive OR << left shift >> right shift
- 8. Assignment operators Operator Description Example = assigns values from right side operands to left side operand a=b += adds right operand to the left operand and assign the result to left a+=b is same as a=a+b -= subtracts right operand from the left operand and assign the result to left operand a-=b is same as a=a-b *= mutiply left operand with the right operand and assign the result to left operand a*=b is same as a=a*b /= divides left operand with the right operand and assign the result to left operand a/=b is same as a=a/b %= calculate modulus using two operands and assign the result to left operand a%=b is same as a=a%b
- 9. Conditional operators âą The conditional operators in C language are known by two more names âą Ternary Operator âą ? : Operator âą Eg: expression 1 ? expression 2: expression 3
- 10. Special Operators Operator Description Example sizeof Returns the size of an variable sizeof(x) return size of the variable x & Returns the address of an variable &x ; return address of the variable x * Pointer to a variable *x ; will be pointer to a variable x
