关系运算符 - 维基百科，自由的百科全书
网页2023年10月21日 · 关系运算符 在计算机科学的 编程语言 中，是测试或定义两个实体之间某种 关系 的构造或操作符。 一共有六种关系，分别为： 小于(<) 、 大于(>) 、 小于或等于(<=) 、 大于或等于(>=) 、 等于(==) 和 不等于(<>)。 在具备 布尔类型 的编程语言中（如 Pascal，Ada 或 Java），这些运算符通常根据两个 操作变量 之间的条件关系是否成立，判定为真 (True)或假 (False)。 诸如 C 语言中关系运算符传回整数 0 或 1，其中 0 表示假， …
Java Relational Operators with Examples - GeeksforGeeks
网页2023年3月25日 · Java Relational Operators are a bunch of binary operators used to check for relations between two operands, including equality, greater than, less than, etc. They return a boolean result after the comparison and are extensively used in looping statements as well as conditional if-else statements and so on.
C++ Relational and Logical Operators (With Examples)

C Relational Operators with Examples - w3resource
网页3 天之前 · Relational operators are essential for making decisions in C programs. They compare values and return a Boolean result, which helps control the flow of the program in conditional statements. The result of the comparison is either true (1) or false (0). These operators are essential in decision-making structures like if, while, and for loops.
关系运算符：<、>、<= 和 >= | Microsoft Learn
网页2023年4月2日 · 关系运算符的两个操作数必须是算术或指针类型。 它们将生成 bool 类型的值。 如果表达式中的关系为 false，则返回的值为 false (0)；否则返回的值为 true (1)。 示例.

Relational Operators - Michigan Technological University
网页There are six relational operators: < : less than. <= : less than or equal to. > : greater than. >= : greater than or equal to. == : equal to. /= : not equal to. Here are important rules: Each of these six relational operators takes two operands. These two operands must both be arithmetic or both be strings.
