The relational operators are used to compare two values and tell you whether the comparison being made is true or false. For example, in the second line in the table, we are testing to see whether x is less than or equal to y. If it is true, this expression will return a non-zero...

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。 2)C语言没有“之间”、“中间”、“...
iiii Output In the above code, thewhileloop continues to iterate till the expression "!(i > 5)" becomes false, which will be when the value of "i" becomes more than 5. i = 0 i = 1 i = 2 i = 3 i = 4 i = 5 C has bitwise counterparts of the logical operators such as bit...
If in a problem there are multiple operators present, then this type of problem is solved according to this order of operator groups. Relational operator is the member of this operator groups. There are many types of relational operators present in C language. They are Lesser than ( < ), ...
2. Relational Operators in C It is also known as comparison operator because it compares the values. After comparison it returns the Boolean value i.e. either true or false. Operator Operator Name Description Example == Equal to If the values of two operands are equal then it returns true....
See the precedence information in the table Precedence and Associativity of C Operators.The operands can have integral, floating, or pointer type. The types of the operands can be different. Relational operators perform the usual arithmetic conversions on integral and floating type operands. In ...

下表显示了 Objective-C 语言支持的所有关系运算符。假设变量 A 为10,变量 B 为20,则运算符描述实例 == 检查两个操作数的值是否相等;如果是,则条件变为 true。 (A == B) 不为 true。 != 检查两个操作数的值是否相等;如果值不相等,则条件变为 true。 (A != B) 为 true。
