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:

Example This example illustrates the unary prefix decrement operator: 复制 if( line[--i] != '\n' ) return; In this example, the variable i is decremented before it is used as a subscript to line. See Also Reference C Unary Operators中文...
The final two general arithmetic operators are the increment and decrement operators. Both are unary operators, so only one operand is required and they may be placed on either side of the operand. If the entire statement consists of just the operand and this operator, then whether the operator...
When we apply post-increment or decrement operator on the operand (operand should be lvalue) then the compiler may create a copy of the operand and increment or decrement the value of the operand respectively. Let’s take an example,
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 ...
When used in postfix mode, it decrements its operand, but evaluates to the value of that operand before it was decremented. Let's take an example to see the behavior of prefix and postfix form of Java's decrement operator. int x = 5, y; // Demonstrating prefix decrement // first x ...
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...
