Increment operators and decrement operators are shorthand methods employed in programming languages such as C++ and Octave for writing frequently occurring operations. They function to increase or decrease the numeric type of variable.

There are a number of operators that can be applied in an incremental or decremental fashion. These are:

• ++; counter++, or ++counter; Adds one to the variable and stores the new number in that variable.
• - - ; counter - -, or - - counter; Subtracts one from the variable and stores the new number.
• +=; counter +=specified number; Adds the number to the variable and stores the new number.
• _=; counter _=specified number; Adds the number to the variable and stores the new number.
• *=; counter *=specified number; Multiplies the variable by the number and stores the new number.
• /=; counter /=specified number; Divides the variable by the number and...
