import java.util.Arrays; public class Kata { public static int findShort(String s) { int shortestLocation = null; this ^^ line needs to be initialized to an integer… not ‘null’ 0 is fine String[] words = s.split(“”); int shortestLength=(words[0]).length(); for(int i=1;i<words.length;i++){ your problem starts here ^^ you never iterate through all of the words as you stop … Read more
Right… I had found the downvotes strange… you guys almost gave me a sad birthday 😛 turns out the issue wasn’t understandable till you fall in the trap. Found the solution in one of these obscure web places 😉 Here you go: Somehow pages loaded into other pages through certain methods (ajax being one?) get … Read more
Returning a pointer isn’t a problem as long as it points to memory that is still in scope, such as dynamically allocated memory, global data, or local variables that still exist further up the call stack. The problem with the above code is that you’re dereferencing a pointer without assigning anything to it. This: *ret_val … Read more
In your array declaration and definition of calc_comp_total, Salesman has not yet been defined, nor declared. The simple fix is to move the definition of Salesman above those constructs. However, you might be better off defining it in a header file, then including that in your implementation file. 2 solved C++ errors when structures not … Read more
I believe it should be because of lexical scoping or static scoping along with function scoping. lexical scoping says variable scope is dependent on when the function was created in your cases when function b was created num was scoped to global. function b() { console.log(num)//num is scoped to its parent function it was created … Read more
Create Class With Same Package public class Hello { public void print(){ int a = 10; System.out.println(“Number is :” +a); } } Crate Class to Set the Main Method Within the Same Package of Hello Method public class Main { public static void main(String args[]){ Hello h1 = new Hello(); h1.print(); } } solved why … Read more
Try changing var to let. This allows to access your version inside your specs. describe(‘Nodeprojectpart2Component’, () => { let version = ”; beforeEach(() => { version = ‘1.0’; }); it(‘test’, () => { console.log( ‘version’ + version); }); }); Issue with your code – Your are retrieving the value of version inside an asynchronous/callback function. … Read more
when it is needed/best practice to use the keyword this This is usually used when you want to access something in some. So for instance, if you have a custom object and want to use some property inside some method, you should use this. function Person(fname, lname){ this.fname = fname; this.lname = lname; this.fullName = … Read more
Introduction This article will discuss the use of the keyword “this” in Javascript. We will look at when it is appropriate to use “this” and when it is not. We will also discuss the different ways in which “this” can be used and the implications of using it incorrectly. By the end of this article, … Read more
1) What is the use of the scope resolution operator in cases like the following, when we can also define it inline? In your example, the scope resolution operator is not required when defining a method inside a class: class Box { public: double length; // Length of a box double breadth; // Breadth of … Read more
EDIT: Since according to the OP, the code is in a function, and score is defined, this is more than likely a case of the computer being a jerk. Restart should theoretically solve the problem. The code’s logic is correct as it stands. Syntactically, there are two major problems: it must be in a function, … Read more
You can make the scopes non-overlapping using braces: switch (something) { case 1: { int Number; } break; case 2: { float Number; } break; } Going out of scope is the only way a variable name is “deleted” in the sense you are talking about. Notably and unlike some other languages, C# doesn’t allow … Read more
That is not possible. From the standard, 6.7 Declarations (emphasis mine): If an identifier has no linkage, there shall be no more than one declaration of the identifier (in a declarator or type specifier) with the same scope and in the same name space, … As to no linkage, 6.2.2 Linkages of identifiers (emphasis mine): … Read more
Any control structure (if, for, while, etc.) without braces applies only to the next statement. The second example is equivalent to the following: for (int i = 0; i < 10; i++) { continue; } cout << i << endl; Note that it’s often considered bad style to have control structures without braces, because people … Read more
