C provides two unique unary operators: ++ (increment) and -- (decrement). These operators are used to add or subtract 1 to/from a variable, and they come in two forms: prefix and postfix. ++m; or m++; — increments the value of m by 1. ...
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...

In C language, the increment and decrement ___ can only be applied to variables, so an expression like x=(i+j)++is illegal. A.operationB.operateC.operatorD.operand 相关知识点: 试题来源: 解析 A [解析] 译文的含义是:在C语言中,增量和减量( )只能应用于变量,所以,x=(i+j)++这样的...
Increment and Decrement Operators: ++ --作为前缀 Assignment Operators: = += -= *= /= %=(a %= b ; a = a%b ) Logical operators:返回1或者0。&&: and ||: or !: not Relational operators:关系为真则为1,假时返回值就是0。<, >, <=, >= == (equality), != (inequality) ...

Operands of the postfix increment and decrement operators are scalar types that are modifiable l-values. Syntax postfix-expression: postfix-expression++ postfix-expression-- The result of the postfix increment or decrement operation is the value of the operand. After the result is obtained, ...
