You can compare them like this: $testing = Array(true, true, true); if($testing == array(true, true, true)){ //do something }else if ($testing == array(true, true, false)){ //do something else } You don’t need to use the same variable $testing again. Just create a new array to compare it with. 1 solved How to write an if(or … Read more
There are a few ways to interpret your question, // this was missing a size. So we need to add one. int x = 10; String []s = new String[x]; String s[] = new String[x]; // This is the same as the previous line. The other form type of question is this, //These are two … Read more
It seems that this declaration: int scores[5]; Is incorrect. This creates an array with 5 numbers in it, indices from scores[0-4], however, you constantly refer to score[5], the sixth element of the array throughout your program. I recommend changing to int scores[6]; 2 solved Error when accessing array – stack around the variable ‘scores’ was … Read more
Note, that std::min_element() returns an iterator to a minimal value, not the value itself. I doubt that you get this error based on the above code alone: assuming proper include directives and using directives the code compiles OK although it would print the address of the minimum element rather than its value. Most likely your … Read more
you can find a typical solution here ` #include<stdio.h> void swap(int *a, int *b); void segregateEvenOdd(int arr[], int size) { /* Initialize left and right indexes */ int left = 0, right = size-1; while (left < right) { /* Increment left index while we see 0 at left */ while (arr[left]%2 == 0 && … Read more
You’re trying to use float values as array indexer in the code fragments like: noise[x1, y1]. Array indexers can be only integers in .NET, but you’ve declared them as float x1, y1. 2 solved “Cannot Implicitly convert type ‘float’ to ‘int’” even when I’m not using any ints
Using the djikstra pathfinding-like logic, build a map of steps to each point while keeping track of the path to it: var obs = [ { from: “A”, to: “C”, dis: 5 }, { from: “A”, to: “D”, dis: 4 }, { from: “D”, to: “C”, dis: 8 }, { from: “C”, to: “B”, dis: … Read more

First, “sample” is called a string literal. It declares a const char array terminated with a null character. Let us go on: char arr[]=”sample”; The right hand part in a const char array of size 7 (6 characters and a ‘\0’. The dimension of arr is deduced from its initialization and is also 7. The … Read more
nextInt() consumes the entire token 013601267, not just a single digit, which was not your plan. A much easier approach could be to consume it as a single string and then iterate over the characters: String num = s.next(); int sum = 0; for (int i = 1; i <= num.length(); ++i) { sum += … Read more
int arr[4][3][2] means arr is 3D array, consists four 2D array, each 2D array having three 1D array and each 1D array having two-two elements. Let’s Have a pictorial representation of arr : Assume arr base address is 0x100. arr[0][0][0] arr[1][0][0] arr[2][0][0] arr[3][0][0] 0x100 0x104 0x108 0x112 0x116 0x120 0x124 0x128 0x132 0x136 0x140 0x144 … Read more

Don’t create individual string array.You can use Arraylist to make a dynamic String array. ArrayList<String> images =new ArrayList<String>(); to insert values.Just use add() method. For example,You want to store iamgeUrls then : images.add(image1); images.add(image2); And to retrieve data use get() method.Example : images.get(position); //where position is the index of imageUrl you want to retrieve. 0 … Read more
