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.

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

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:

modulo(remainder of an integer
division)
