In the example above, if the discount is 10%, then the first if statement will be evaluated as true and "you have to pay $30" will be printed out. All other statements below that first if statement will be skipped. The elseif statement, in the Ada language for example, is simply syntactic sugar for else followed by if.
In such case it is always possible to use a function call, but this can be cumbersome and inelegant. For example, to pass conditionally different values as an argument for a constructor of a field or a base class, it is impossible to use a plain if-else statement; in this case we can use a conditional assignment expression, or a function call ...
If no matching case is found, then the default value is used. This is usually specified last with no associated "case" value, as seen in the syntax summary above, but it can also be specified at any point after the test string if the construct | #default = value is used (see the second example below). If no default is specified in either way ...
For example, in the conditional statement: "If P then Q", Q is necessary for P, because the truth of Q is guaranteed by the truth of P. (Equivalently, it is impossible to have P without Q , or the falsity of Q ensures the falsity of P .) [ 1 ] Similarly, P is sufficient for Q , because P being true always implies that Q is true, but P not being ...
var x1 = 0; // A global variable, because it is not in any function let x2 = 0; // Also global, this time because it is not in any block function f {var z = 'foxes', r = 'birds'; // 2 local variables m = 'fish'; // global, because it wasn't declared anywhere before function child {var r = 'monkeys'; // This variable is local and does not affect the "birds" r of the parent function. z ...
The test case is collapsed and given a green heading if all the template outputs are the same. If any of the template outputs differ, the test case is expanded and given a yellow heading. _resetRefs: If set to "yes", any references generated by the templates tested are reset after each template is expanded. _showcode: Show the template code ...
If set to "y" or "yes", the test case is made collapsible. The test case is collapsed and given a green heading if all the template outputs are the same. If any of the template outputs differ, the test case is expanded and given a yellow heading. See #Collapsible test cases for other parameters which only work when _collapsible is enabled.
If this is set to "no", then no output is shown for that template. This is useful if you only want to show the main template, or if you only want to show the sandbox template. _collapsible: If set to "yes", the test case is made collapsible. The test case is collapsed and given a green heading if all the template outputs are the same.
