int a[5] a is an array of 5 int. int (*a)[5] a is a pointer to an array of 5 int. int a[5][4] a is an array of 5 array of 4 int. int *a[5] a is an array of 5 int pointers. 6 solved What’s the difference between “int a[5]” and int (*a)[5], int … Read more
Try below java code public static int[] reverse(int[] a, int number) { // negative case if (number < 0) { return a; } // higher count than array length int size = number < a.length ? number : a.length; int[] b = new int[size]; System.arraycopy(a, 0, b, 0, size); for (int i = b.length – … Read more
This will fill the array with a range of 1 – N: public class NurTests { public static void main(String[] args) { int [] arr = new int[100]; int value = 1; for(int i = 0; i < arr.length; i++){ arr[i] = value; value ++; } } } A simpler way to do it, you … Read more
There is none. Once the array-to-pointer conversion happens, the size information is gone. If you need it, you have to pass the size as a separate argument. Since pArr is a pointer, sizeof(pArr) gives the size of the pointer. Your pointers seem to be double the size of ints; that is the case on x86-64, … Read more
You will want to do the following: char *gg = “hello”; printf( “%c\n”, gg[3] ); This will print the fourth character (zero based array = 0, 1, 2, 3 so 0=’h’, 1=’e’, etc). Change the 3 to which ever character you want, but make sure to not go past the end of the string. strlen … Read more
Every time you append the * in the builder object, clear the previous content. You can use stringBuilder.setLength(0); import javax.swing.*; public class Prop { public static void main(String args[]) { StringBuilder stringBuilder = new StringBuilder(); int n = 0; n = Integer.parseInt(JOptionPane.showInputDialog(“Enter value”)); int[] arr = new int[n]; String stars = “”; int input = … Read more

Three loops for each array. Just loop through every array, and append to new array. var size = [‘s’,’m’]; var color = [‘red’,’blue’,’black’]; var material = [‘cotton’,’linen’]; var arrayMaterials = [] for (var i = 0; i < size.length; i++) { for (var j = 0; j < color.length; j++) { for (var k = … Read more
Using the algorithm you propose in your question (i.e. to first find all unique values and then find the lowest one), a possible implementation looks like this: #include <stdio.h> #include <stdlib.h> // NOTE: The second parameter array_size specifies the number of // int elements in the array, NOT the size of the array in bytes. … Read more
You mean to do: while iterations < itemsInListOne: listOne[iterations] = float(listOne[iterations]) + 1 Note that you needed to convert it to a float before adding to it. Also note that this could be done more easily with a list comprehension: listOne = [float(x) + 1 for x in listOne] solved How can I increment array … Read more
If you need a 2d array, you have to initialize each element of the outer array to be an array. // Have to check every array item, if it’s not an array already, make it so for(…) { if (!data[key]) { data[key] = []; } data[key].push(item[i]); } You could always do the following if you … Read more
You need to do this: foreach ($menu_items as $item=>$value) { if($item != ‘about-me’){ echo ‘<a href=”#’.$item.'”>’.$value.'</a>’; //change here }else if($item == ‘about-me’){ echo ‘<a href=”#’.$item.'”>about</a>’; } } You are using $item, use the $value instead of $item. 0 solved How can I show array in PHP?
Store the value of array[0] in a variable (let’s call it result). Loop from array[1] to the end. In this loop, run through all the values of result. If the current value of result is not in array[x] remove this value from result. At the end of the loop, result only contains the desired values. … Read more
Trying to enumerate all the different possible strings in the array is generally a bad idea and not the correct way to write your program. Sure your example works, but what would happen if your set of possible strings was not just {‘this’, ‘is’, ‘a’, ‘test’}, but instead had say 10000 elements? What if you … Read more
Pretty basic example of using storage folder with xml output/input. You can modify it do what you wish. I use a more complicated version of it for my own windows phone app. I’m assuming you having a hard time writing and reading the data back. If you need help deleting a random element from the … Read more
