Meaning of Comparison, Logical, Assignment and Arithmetic Operators in C++

Comparison and Logical Operators

For program flow, the comparison as well as the logical operators is required. The comparison and logical operators can be grouped into three. They are relational operators, equality operators and logical operators.

OPERATOR	MEANING
<                >              <=              >=              ==              !=              &&              ||               !	Less than      Greater than      Less than or equal to      Greater than or equal to      Equal to      Not equal to      Logical AND      Logical OR      Not

Assignment Operators

An assignment operator is used to assign back to a variable, a modified value of the present holding.

OPERATOR

MEANING

=            +=             -=            *=            /=            %=           >>=           <<=           &=           \=            %=

Assign right hand side (RHS) value to the left hand side (LHS) Value of LHS variable will be added to the value of RHS and assign it back to the variable in LHS Value of RHS variable will be subtracted from the value of LHS and assign it back to the variable in LHS Value of LHS variable will be multiplied by the value of RHS and assign it back to the variable in LHS  Value of LHS variable will be divided by the value of RHS and assign it back to the variable in LHS The remainder will be stored back to the  LHS after integer division is carried out between the LHS variable and the RHS variable Right shift and assign to the LHS Left shift and assign to the LHS Bitwise AND operation and assign to the LHS Bitwise OR  operation and assign to the LHS Bitwise complement and assign to the LHS

Arithmetic Operators

Arithmetic operations are the basic and common operations performed using any computer programming. Normally, these operators are considered as basic operators and known as binary operators as they require two variables to be evaluated. For example, if we want to multiply any two numbers, one has to enter or feed the multiplicand and the multiplier. That is why it is considered as a binary operator. In C++, the arithmetic operators used are as follows:

OPERATOR	MEANING
+                 -                *                /                %	addition               subtraction               multiplication               division               modulo(remainder of an integer division)
