Example 3: Prefix Decrement Operator (--m) This code demonstrates the prefix decrement operator in C. The variable a is initialized to 5. Using the prefix decrement (--a), the value of a is first decremented by 1, and then the new value (which is 4) is printed. ...

The argument of type int that denotes the postfix form of the increment or decrement operator isn't commonly used to pass arguments. It usually contains the value 0. However, it can be used as follows: C++ Copy // increment_and_decrement2.cpp class Int { public: Int operator++( int ...
This example illustrates the unary decrement operator: if( line[--i] != '\n' ) return; In this example, the variable i is decremented before it is used as a subscript to line. Because increment and decrement operators have side effects, using expressions with increment or decrement operato...
C++ provides prefix and postfix increment and decrement operators; this section describes only the postfix increment and decrement operators. (For more information, seePrefix Increment and Decrement Operators.) The difference between the two is that in the postfix notation, the operator appears afterpos...
Similar to incrementing variables, there are some considerations when decrementing variables. One common mistake is using the decrement operator incorrectly, which can lead to unexpected results. It's important to understand the language-specific rules and operator precedence to ensure the desired outcome...
The operand of a postfix increment operator may also be of type bool, in which case the operand is evaluated and then set to true. The operand of a postfix decrement operator cannot be of type bool.The following code illustrates the postfix increment operator:...
