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...
The above programming example is also another example of relational operator. Here, we solve another expression. The expression is: [cc lang=”c” width=”100%” height=”100%” escaped=”true” theme=”blackboard” nowrap=”0″ line_numbers=”on”]x= 9 ==8 ; Here, two operators are...

These check the relationship between the operands and return a result in a boolean (true or false).These comparisons are based on conditions like equality, inequality, greater than, less than, etc.Relational operators are a fundamental part of a programming language as they help in decision-...
Java provides special operators that can be used to combine(结合) an arithmetic operation with an assignment. As you probably know, statements like the following are quite common in programming. a=a+4; In Java, you can write this statement as shown here : ...
Equality and relational operators in Java are called comparison operators. There are two equality operators: equals to (==) and not equals to (!=) they test if two values are equal or not. Whereas, relational operators used with ordered types (numbers and characters) to test for greater ...
Relational operators can be used with various data types in Scala, like numbers, strings, characters, etc. You compare based on the lexicographical order (dictionary order) of the characters in the strings. You can chain multiple relational operators together using logical operators (&&, ||) for...
In every programming language including python, to manage the flow of any program, conditions are required, and to define those conditions, relational and logical operators are required.Remember those days when your mathematics teacher in school used to ask you if 3 is greater than 2, say yes,...
The equality and relational operators determine if one operand is greater than, less than, equal to, or not equal to another operand. The majority of these operators will probably look familiar to you as well. Keep in mind that you must use "==", not "=", when testing if two ...
The definitions of temporal relational operators used in the temporal relational algebra are different from that of the conventional relational algebra as they support time element. A new optimized model to handle temporal data using open source database Relational Algebra and###Effective usage of rela...
