Flow control structures (Introduction to Java. Script)programs that can be done using only variables and operators are a simple linear succession of basic instructions. However, you can't make programs that display a message if the value of a variable is equal to a particular value and not to show the message in the rest of cases. Nor can repeat efficiently a same instruction, e.g. To perform this type of programs are necessary flow control structures, which are statements of the type if this condition is met, do this; if not met, do this. There are also instructions on the type repeats this as long as this condition is met. If you use flow control structures, the programs are no longer a linear succession of instructions to become a programs smart that they can make decisions based on the value of the variables. If structure. The most common structure in Java. Script and in most programming languages is the if structure. It is used to make decisions in function of a condition. Its formal definition is: If the condition is met (i.e., if its value is true) is executed all the instructions that are inside. Enter a number and convert to letters – Flow Diagram. Problem Enter a number and convert to letters. September 23, 2015, 23:28. Aprender The LetrasSi the condition is not met (i.e., if its value is false) does not execute any instruction contained in. Example: var most Message true. Message). alert(Hello World); In the above example, the message yes is displayed to the user as the variable most Message has a value of true, and therefore, the program enters the statement block of the if. The example could be rewritten also as: var most Message true. Message true). Hello World); In this case, the condition is a comparison between the value of the variable most Message, and the true value. As the two values match, the equality is true and therefore the condition is true, its value is true, and execute the instructions contained in that block of the if. The Zoo Of The LetrasLa comparison of the above example is the source of many programming errors, by confusing the operators and . The comparisons are always made with the operator , because the operator only assigns values: var most Message true. Comparing the two valoresif(most Message, false). Error Is assigned the value false to the variableif(most Message, false). The condition controlling the if() you can combine the different relational and logical operators shown above: var shown false. This is the first time the message is shown); The operators and and OR allow you to chain together multiple conditions simple to build complex conditions: var shown false; var user. Allows. Messages true. Allows. Messages). This is the first time the message is shown); The above condition is formed by an AND operation on two variables. At the same time, the first variable we apply the negation operator before performing the AND operation. Growth And Other Lies Poster (2015) Video Download here. In this way, as the value displayed is false, the value As the variable user. Allows. Messages set to true, the result of Allows. Messages would be equal to true to true, so that the final result of the condition of the if() would be true and therefore, executes the statements inside the block of the if(). Exercise 5. To complete the conditions of the " if the following script so that the messages of the alert() to always display in the correct way: var number. Increase in 1 unit the value of number. See solution. 3. 4. If structure. else. At times, decisions that should be made are not of the type if the condition is met, do this; if not met, do nothing. Usually the conditions are usually of the type if this condition is met, do this; if not met, do this. For this second type of decisions, there is a variant of the structure if call if. Its formal definition is the following: if(condition). If the condition is met (i.e., if its value is true) is executed all the instructions that are within the if(). If the condition is not met (i.e., if its value is false) execute all the instructions contained in the else . Example: var age 1. You are of legal age); else. You are still a minor); If the value of the variable age is greater than or equal to the numeric value 1. You are of legal age. However, when the value of the variable age is not equal to or greater than 1. In this case, it would show the message you are Still a minor. The following example compares variables of type string: var name . Even we don't have said your name"); else. We have saved your name); the condition of The if() above is constructed by the operator , which is used to compare two values (not to be confused with the operator that is used to assign values). In the above example, if the text string stored in the name variable is empty (i.e., it is equal to ) displays the message defined in the if(). In another case, it shows the message defined in the else block . The if structure. You are still very small); elseif(age lt; 1. You're a teenager); elseif(age < 3. Even you're still young); else. Think take care of yourself a little bit more); it is Not mandatory that the combination of structures if. Exercise 6. The calculation of the letter of the National Identity Document (DNI) is a simple mathematical processing that is based on get the rest of the integer division of the ID number and the number 2. From the rest of the division, you get the letter by selecting it within an array of letters.
