Postfix Increment and Decrement Operators:  ++, --

  • 项目

postfix-expression :

postfix-expression ++
postfix-expression --

Operands of the postfix increment and decrement operators are scalar types that are modifiable l-values.

The result of the postfix increment or decrement operation is the value of the postfix-expression before the increment or decrement operator is applied. The type of the result is the same as that of the postfix-expression but is no longer an l-value. After the result is obtained, the value of the operand is incremented (or decremented).

For more information, see Prefix Increment and Decrement Operators.

Example

In the following example, the for loop is iterated 10 times. After each iteration, the nCount variable increased by +1 using the postfix increment operator.

// Example of the postfix increment operator
for (nCount = 0; nCount < 10; nCount++) {
   nTotal += nArray[Count];
}
