  • Struct Array Initialization and String Literals

    - by Christian Ammer
    Is following array initialization correct? I guess it is, but i'm not really sure if i can use const char* or if i better should use std::string. Beside the first question, do the char pointers point to memory segments of same sizes? struct qinfo { const char* name; int nr; }; qinfo queues[] = { {"QALARM", 1}, {"QTESTLONGNAME", 2}, {"QTEST2", 3}, {"QIEC", 4} };

  • How to deal with JSON output that might be an array, or might be a value

    - by Summer
    Hi - I'm getting JSON-encoded output from another organization's API. In many cases, the output can be either an array of objects (if there are many) or an object (if there's just one). Right now I'm writing tortured code like this: if ( is_array($json['candidateList']['candidate'][0]) ) { foreach ($json['candidateList']['candidate'] as $candidate) { // do something to each object } } else { // do something to the single object } How can I handle it so the "do something" part of my code only appears once and uses a standard syntax?

  • Retrieving data from a JSON sub array in javascript, where identifier starts with an integer

    - by Archie Ec
    I must be missing something simple here, but I'm having trouble retrieving data from a JSON array response. I can access objects with identifiers that start with letters, but not ones that start with numbers. For example, I can access data.item[0].specs.overview.details But I can't access data.item[0].specs.9a99.details If anyone can point me in the right direction, I'd really appreciate it. Thanks.

  • C# Implicit array declaration

    - by The.Anti.9
    Basically, I want to be able to use string.Split(char[]) without actually defining a char array as a separate variable. I know in other languages you could do like string.split([' ', '\n']); or something like that. How would I do this in C#?

  • C++: Pass array created in the function call line

    - by Jarx
    How can I achieve a result like somebody would expect it according to the following code example: // assuming: void myFunction( int* arr ); myFunction( [ 123, 456, 789 ] ); // as syntactical sugar for... int values[] = { 123, 456, 789 }; myFunction( values ); The syntax I thought would work spit out a compile error. How can I define an argument array directly in the line where the function is called?

  • Is String.concat slower than Array approach to join strings

    - by Rajat
    Strings in JavaScript are immutable. Across the web and here on Stack Overflow as well, I came across the Array approach to concatenate strings: var a = []; a.push(arg1,arg,2....); console.log(a.join('')); I know that this approach is better than the simple console.log(arg1 + arg2 +.....); for reasons of skipping creating intermediate objects but how does it fair better against : arg1.concat(arg2,arg3.....);

  • clear all array list data

    - by lolalola
    Hi, Why don't clear all Array list data? Console.WriteLine("Before cleaning:" + Convert.ToString(ID.Count)); //ID.Count = 20 for (int i = 0; i < ID.Count; i++) { ID.RemoveAt(i); } Console.WriteLine("After cleaning:" + Convert.ToString(ID.Count)); //ID.Count = 10 From where 10 data? Maybe there is another special function, which deletes everything?
