The prefix form returns the new value while the postfix form returns the old value prior to incrementdecrement. Increment operators are used to increase the value of the variable by one and decrement operators are used to decrease the value of the variable by one in c programs. The decrement operator decrements the value of the variable by 1 by subtracting 1 from its current value. If you are using prefix form then increment or decrement will be done before rest of the expression, and if you are using postfix form, then increment or decrement will be done after the complete expression is evaluated.

When an increment or decrement is used as part of an expression, there is an important difference in prefix and postfix forms. The increment decrement operator can be used with any type of variable but it cannot be used with any constant. The increment and decrement operators in c are some of the operators, which are used to increase or decrease the value by 1. Even if guaranteed, im quite aware using incrementdecrement can quickly become an issue for readability. There is no chaining of comparison operators in c in python, expression like c b a is treated as c b and b a, but this type of chaining doesnt happen in c.

Because of the sideeffects involved, builtin increment and decrement operators must be used with care to avoid undefined behavior due to violations of sequencing rules because a temporary copy of the object is constructed during postincrement and postdecrement, preincrement or predecrement operators are usually more efficient in contexts where the returned value is not used. Lets see one example of increment and decrement operators to get a better idea. We have already studied the pre and post increment operators in c programming.
