Did you know?
WebC programming has two operators increment ++ and decrement -- to change the value of an operand (constant or variable) by 1. Increment ++ increases the value by 1 whereas decrement -- decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand. Example 2: Increment and Decrement Operators WebAug 2, 2024 · 通过以上方法创建数组，其中 Array (3) 中的参数 3 表示数组的长度，这个数组就是稀疏的，控制台输出一般带有 empty 字样，或者像下面这样创建数组：. var arr = …
