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. Code: #include <stdio.h> int main() { int a = 5; // P...

Learn about C++ increment and decrement operators, their usage, types, and examples to enhance your programming skills.
The -- operator decrements its single operand by one. The behavior of decrement operator during an assignment operation depends on its position relative to the operand whether it is used in prefix or postfix mode. When used in prefix mode, it decrements the operand and evaluates to the decre...
postfix-expression --The result of the postfix increment or decrement operation is the value of the operand. After the result is obtained, the value of the operand is incremented (or decremented). The following code illustrates the postfix increment operator.C Salin ...

Point& Point::operator--() { _x--; _y--; return *this; } // Define postfix decrement operator. Point Point::operator--(int) { Point temp = *this; --*this; return temp; } int main() { } The same operators can be defined in file scope (globally) using the following function...
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 afterpo...
