The n variable was declared in the main method and thus is visible only in the main method, nowhere else, and certainly not inside of the calcNumFactors method. To solve this, give your calcNumFactors method an int parameter which would allow calling methods to pass an int, such as n into the method. and call it like so:
You are using a function for which the compiler has not seen a declaration (“prototype“) yet. For example: You need to declare your function before main, like this, either directly or in a header:
You should add the target=”_blank” and rel=”noopener noreferrer” in the anchor tag. For example: Adding rel=”noopener noreferrer” is not mandatory, but it’s a recommended security measure. More information can be found in the links below. Source: MDN | HTML element <a> | attribute target About rel=noopener Opens External Anchors Using rel=”noopener”
Modern browsers have Array#includes, which does exactly that and is widely supported by everyone except IE: Run code snippet You can also use Array#indexOf, which is less direct, but doesn’t require polyfills for outdated browsers. Run code snippet Many frameworks also offer similar methods: jQuery: $.inArray(value, array, [fromIndex]) Underscore.js: _.contains(array, value) (also aliased as _.include and _.includes) Dojo Toolkit: dojo.indexOf(array, value, [fromIndex, findLast]) Prototype: array.indexOf(value) MooTools: array.indexOf(value) MochiKit: findValue(array, value) MS … Read more
I am experiencing an error while trying to compile Java programs. I am on Windows (this is a Windows-specific problem) and I have the latest JDK installed. I have attempted a solution involving the PATH variable, but the error persists. Console output:
Consider a simple function that adds the first N natural numbers. (e.g. sum(5) = 0 + 1 + 2 + 3 + 4 + 5 = 15). Here is a simple JavaScript implementation that uses recursion: If you called recsum(5), this is what the JavaScript interpreter would evaluate: Note how every recursive call has to complete before … Read more
If they have just changed the oncontextmenu handler (which is the most straightforward way to do it), then you can remove their override thus: Otherwise, if it is attached to individual elements, you can get all the page’s elements, and then remove the handler on each one: Or, it seems you can turn off such scripts; via an … Read more
Assuming you’re joining on columns with no duplicates, which is a very common case: An inner join of A and B gives the result of A intersect B, i.e. the inner part of a Venn diagram intersection. An outer join of A and B gives the results of A union B, i.e. the outer parts of a … Read more
Strings in python are immutable, so you cannot treat them as a list and assign to indices. Use .replace() instead: If you need to replace only certain semicolons, you’ll need to be more specific. You could use slicing to isolate the section of the string to replace in: That’ll replace all semi-colons in the first 10 characters of the … Read more
Many web servers will have a ‘default document’ that is returned when you specify just a path and no file name. So browsing to http://example.com will return the default document from the document root directory of that domain. Quite often the default document can be named index.html, index.htm or -if PHP is installed- index.php, but … Read more
