Dear all, here's a very basic question, that I'm sure you will be able to answer quickly. Please don't laugh at my ignorance. I have a string, that I want to compare to an array of strings. Only if the string is not part of the array, I want to perform an operation. I tried the following code, that doesn't work. I do understand why, bu...
I know that instantiated arrays of value types in C# are automatically populated with the default value of the type (eg false for bool, 0 for int, etc etc). Is there a way to autopopulate an array with a seed value that's not the default? Either on creation or a built in method afterwards (I believe Java has something like Array.Fill() ...
Given the following function: function process_pipes(text) { split(text,recs,"|"); for (field in recs){ printf ("|%s|\n", field) } } If the input is: 0987654321|57300|ERROR account number not found|GDUMARESQ|0199|9|N|0|| Why do I get the numbers below instead of the text? |4| |5| |6| |7| |8| |9| |10| |1| |2| |3|...
char **Data[70]={NULL}; What is the correct terminology for this? How else could it be written? What does it look like in memory? I am reading many tutorials on pointers but I don't see it in this syntax. Any help is appreciated. Thanks. ...

Hello, I've tried to pass an initialization list {...} to a constructor and it didn't work. When I instead declared it in a method local variable (int[]) it worked flawlessly. Why is that? public class QuickSort { int[] a; public QuickSort(int[] a) { this.a = a; } public static void main(String[] args) { //...
I use the following code to convert an object array to a string array : Object Object_Array[]=new Object[100]; // ... get values in the Object_Array String String_Array[]=new String[Object_Array.length]; for (int i=0;i<String_Array.length;i++) String_Array[i]=Object_Array[i].toString(); But I wonder if there is another way to do thi...
Is there any fast way to get all subarrays where a key value pair was found in a multidimensional array? I can't say how deep the array will be. Simple example array: $arr = array(0 => array(id=>1,name=>"cat 1"), 1 => array(id=>2,name=>"cat 2"), 2 => array(id=>3,name=>"cat 1") ); When I search for key=name a...
I have a byte array that contains 6 bytes last 2 represents the port number while searching for a way two convert these last to bytes to a port number i have come across this snippet, int port = 0; port |= peerList[i+4] port <<= 8; port |= peerList[i+5] it works but i need some clarification as to how it w...
I'd like to generate a number of objects (in C++) based on the amount/number the user enters. Now I've somewhere heard that it has to be done using pointer tricks, creating a pointer to an array of the Object type required, and then dynamically increasing the size of array ( at runtime ). Isn't there a workaround of directly using name...
I want to pass 2 arrays to a function in Java and have them sorted in the calling function. How do i use a function to accomplish that? I could have the function return an object with 2 arrays, but is there a non object-oriented solution to this? EDIT : I this particular situation I cant use the inbuilt Array.sort function in Java. ...
I'm starting to learn C by reading K&R and going through some of the exercises. After some struggling, I was finally able to complete exercise 1-19 with the code below: /* reverse: reverse the character string s */ void reverse(char s[], int slen) { char tmp[slen]; int i, j; i = 0; j = slen - 2; /* skip '\0' and \n */ tm...
I would like to create an object array in C# of undefined length and then populate the array in a loop like so... string[] splitWords = message.Split(new Char[] { ' ' }); Word[] words = new Word[]; int wordcount = 0; foreach (string word in splitWords) { if (word == "") continue; words[wordcount] = n...
Problem: I have two arrays that can possibly be different lengths. I need to iterate through both arrays and find similarities, additions, and deletions. What's the fastest and most efficient way to accomplish this in C#? Edit: The arrays are pre-sorted and they can contain anywhere between 50-100 items. Also, there aren't any const...
I need a multidimensional array of chars that is dynamic in only one dimension... I have to store a pair of strings with a length of 10 (or less) chars each, but with a variable number of "pairs". My idea was this char (*instrucao)[2][10]; Which gives me a pointer to a 2x10 array of chars, but this is not working properly when i do s...
I have 2 separate arrays, one is just the id's the other is the percentage Id's: Array ( [0] => 3 [1] => 4 [2] => 5 [3] => 6 [4] => 7 } Percent array: Array ( [0] => 28 [1] => 39 [2] => 17 [3] => 28 [4] => 23 So it would end up like: Array ( [0] => Array ( [id] => 3 [percen...
