首先看这两类都实现List接口,而List接口一共有三个实现类,分别是ArrayList.Vector和LinkedList.List用于存放多个元素,能够维护元素的次序,并且允许元素的重复.3个具体实现类的相关区别如下:1.ArrayList是最常用的List实现类,内部是通过数组实现的,它允许对元素进行快速随机访问.数组的缺点是每个元素之间不能有间隔,当数...
运算符(Operators)是一种符号,它告诉编译器执行特定的数学或逻辑操作。C语言内置了丰富的运算符,提供了以下几种运算符。 算数运算符(Arithmetic Operators) 关系运算符(Relational Operators) 逻辑运算符(Logical Operators) 位运算符(Bitwise Operators) 赋值运算符(Assignment Operators) 杂项运算符(Misc Operators) 本...
1.Description Methods of Algorithms 二、关系运算符 2.Relational Operators 关系表达式：用关系运算符将两个操作数连接起来组成的表达式。Relational Expression: An expression formed by connecting two operands with relational operators.用非0值表示“真”，用0值表示“假”。例如，可将n%2 !=0简写为n%2。Use...
关系运算符(Relational Operators):< <= > >= ==(等于) !=,他们都是双目运算符,左结合。 赋值运算符:基本的赋值运算符是“=”。除此之外还有+= -= *= /= %= &=(按位与赋值) |=(按位或赋值) ^=(按位异或赋值) <<= >>=(左/右移位赋值) 优先级:括号>自增++、取值*、取地址&、非!、按位...
在讲if条件分支结构之前,先了解关系运算(Relational Operators),用于判断条件,决定程序的流程。 C语言的基本数据类型有char、int、double,我们暂时认为只有char和int适用于上述关系运算符,double和字符串(字符数组)的关系运算以后再讨论。 注意了: 1)“=”是赋值,“==”才是判断两个数是否相等,不能混用。

REMEBER : You should limit yourself to using only < and > in floating-point comparisons. while(status == 1) is ture. and while(status = 1) is ture ...so advice to write like that while(1 == status).
Similarly, comparing pointers using the relational operators<,<=,>=, and>gives the positions of the pointers relative to each other. Subtracting or comparing pointers that do not refer to the same array is undefined behavior (seeundefined behavior 48andundefined behavior 53). ...
