This expression can be read as “n less than or equal to 200.” The “less than or equal to” operator (which is the less than character [<] followed immediately by the equals sign [=]) is only one of several relational operators provided in the Objective-C programming language. These operators are used to test specific conditions. The answer to the test is yes (or true) if the condition is satisfied and no (or false) if the condition is not satisfied.
