Augmented assignment, which is also called compound assignment, is a type of assignment that gives a variable a value that is relative to its previous value, for example, incrementing the current value. In case the if the statement isnt true then the program will skip the if operation and will directly move out of the if block and will move ahead to the other blocks of codes present after it. , Heres how to do a comparison for a range: Moreover, unlike most programming languages Lua enables reassignment of variables' values through permutation. Called Logical AND operator. you may also have a look at the following articles to learn more .

This makes it appropriate for arrays, where all indices are numeric. retreturn explist. print("Voila !, Rahul age is 5" ) then Not the answer you're looking for? With generic for loops, you can execute code for each item in the collection, and can easily use each item in the code.

This is because one side is evaluated before the other side, so in left-to-right order it ends up going from x < y < z to true < z which is an error, whereas in the explicit method, it goes from x < y AND y < z to true AND y < z to true AND true, to true. The loadfile function can also be used to load code from the standard input, which will be done if no file name is given. lua if statement multiple conditions - Weird Things is just syntactic sugar for Press Enter to auto-complete and add the end.

Connect and share knowledge within a single location that is structured and easy to search. They are always formatted as: The goto statement in Lua. To combine a string with a variable or other strings, a process called concatenation, type .. between the string and the variable name. Square brackets are used to index a table. Most programming languages don't expand the form x < y < z to x < y AND y < z automatically, so you must use the logical and explicitly. sc; The words if, then and end are keywords. Conditional contexts in Lua ( if, elseif, while, until) do not require a boolean. Here, once the program runs, it checks the first block for decision making. It will increment the variable and repeat the code until the variable reaches this number. The string library provides string.gmatch() to iterate over strings. results in a table value, Following table shows all the logical operators supported by Lua language.
