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. ...
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...

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 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,
Decrementxby 1, then usex. Postfix Example 1 2 3 4 x=5; y=(x++)+5; // y = 10 // x = 6 Prefix Example 1 2 3 4 x=5; y=(++x)+5; // y = 11 // x = 6 However, if this operator is used as part of a larger expression, then the position of the operator becomes ...
When specifying an overloaded operator for the postfix form of the increment or decrement operator, the additional argument must be of type int; specifying any other type generates an error. The following example shows how to define prefix and postfix increment and decrement operators for the Point...
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 ...
In C language,the increment and decrement operator can only be applied to (56) ,so an expression like x=(a+b)--is illegal. A.integersB.StringsC.variablesD.pointers 相关知识点: 试题来源: 解析 C [解析] c语言中,自增和自减操作符,只能适用于变量,所以一个类似x=(a+b)--的表达式是非...
