Nesting if statements

if/elseif/else statements control the execution of chunks of code. Like chunks, if statements can be nested. The same rule for scope applies to nested if statements as it does to nested chunks. The following code demonstrates the use of nested if statements:

print ("Enter a number")x = io.read()if x == "6" then    print ("x is six!")    print ("Enter another number")    local y = io.read()    -- Nested if statement begins here    if y == "6" then        print ("y is also six!")    elseif y == "5" then        print ("y is one less than x")    else        print ("x is 6, but y is not!")    end    -- Nested if statement ends hereelse     print ("x is not 6!" .. x)end
