Yuanfang is puzzled with the question below: There are n integers, a 1, a 2, -, a n. The initial values of them are 0. There are four kinds of operations. Operation 1: Add c to each number between a x and a y inclusive. In other words, do transformat
上篇说到Java中的变量与常量,接下来就是简单的计算了,首先需要了解一下Java中的运算符. 六.运算符 1. 赋值运算符 赋值运算符即"=",是一个二元运算符(即对两个操作数进行处理),其功能是将右方操作数所含的值赋值给左方的操作符.其中左方必须是一个变量,而右边所赋的值可以使任何数值或表达式,例子如下: int a = 10; // 将10赋给a int b = 5; // 将5赋给b int c = a+b; // 将变量a和b进行运算后的结果赋给c 也可先定义变量再进行赋值运算
