Operators in c++
- 2. Operators are the foundation of any programming language. Thus the functionality of C++ programming language is incomplete without the use of operators. We can define operators as symbols that help us to perform specific mathematical and logical computations on operands.
- 3. Types of Operators 1. Arithmetic operator 2. Relational operator 3. Logical operators 4. Bitwise operator 5. Assignment operator
- 4. Arithmetic operator Arithmetic operators perform some arithmetic operation on one or two operands. Arithmetic operators are two type:- Unary operator (++ , - -) Binary operator (+ , - , * , / , %)
- 5. Relational operator Relational operators define the relation between two entities. They are mainly use to compare variable with other variable and constant Returns Boolean value. = = Give true value if both operand have equal value != Gives true if both operands are not equal > Gives true if left operand is more than right operand < Gives true if left operand is less than right operand >= Gives true if left operand is more than or equal to right operand <= Gives true if left operand is less than or equal to right operand
- 6. Logical operators These operators are used to combine two or more condition . Result of the operation is Boolean. Operator Example Meaning AND(&&) expression1 && expression2 True only if all the operands are true. OR(||) expression1 || expression2 True if at least one of the operands is true. NOT(!) !expression True only if the operand is false.
- 7. Bitwise operator Bitwise operators are the operators that operate on bits and perform bit-by-bit operations. Operator Description & Bitwise AND Operator | Bitwise OR Operator ^ Bitwise XOR Operator ~ Bitwise Complement Operator << Bitwise Left Shift Operator >> Bitwise Right Shift Operator
- 8. Assignment operator The Assignment operator is used to assign a value to a variable. These are operators used to perform an arithmetic function on an operand and assign the new value to the operand at the same time. Operator Example Equivalent to = a = b; a = b; += a += b; a = a + b; -= a -= b; a = a - b; *= a *= b; a = a * b; /= a /= b; a = a / b; X = 50; Variable Value
