I have some question about how to save generated data in a for looping in a new string

will be helpful for those in need It seems you want to have all the combinations of two characters as strings in an array. BTW: this is not random.
A solution could look like this:
int main(int argc, char *argv[]) {

    string key[] = {
            "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U",
            "V", "X", "Y", "Z", "a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q",
            "r", "s", "t", "u", "v", "x", "y", "z"};

    //num is the number of elements in the array
    int num = sizeof(key) / sizeof(key[0]);
    //dynamically allocate memory for it
    char *combi = malloc(num * num * (sizeof(char) * 3));

    for (int i = 0; i < num; i++) {
        for (int j = 0; j < num; j++) {
            char *buf = combi + (i * num + j) * (sizeof(char) * 3);
            sprintf(buf, "%s%s", key[i], key[j]);

    //verify the result
    int counter = 0;
    for (int i = 0; i < num; i++) {
        for (int j = 0; j < num; j++) {
            char *combination = combi + (i * num + j) * (sizeof(char) * 3);
            printf("[%d]: %s\n", counter++, combination);

    //free the dynamically allocated memory

    return 0;
[0]: AA
[1]: AB
[2]: AC
[2498]: zy
[2499]: zz
char *secondString = combi + 3;
printf("%s\n", secondString);

How to save multiple rows of data by looping through an array or a map?

Tag : grails , By : KS9

wish of those help First, I'm not sure about ["buyer.id": 2, "ref" : e.value], I think it should be [buyer: Buyer.get(2), ref : e.value].
Second, I would recommend using cascading save to do the task. You can try something like this(You need to define a static hasMany = [orders: Order] relation in Buyer for Buyer-Order relationship.
Buyer b = new Buyer(name: "foo")
for(e in items) {
     def ord = new Order(ref: e.value);

will be helpful for those in need Typically I just set the company on the employee when creating the employees.
[newEmployee setValue:company forValue:@"company"];
newEmployee.company = company;

Looping to save data to Core Data with NSPrivateQueueConcurrencyType context leaves loop unexpectedly

wish help you to fix your issue It is because of multi threading. performBlock will be called at some later time on a different thread possibly after method is done. Which means after tempMoc is set to nil. I think you should put the for loop inside the peformBlock like so
        [tempMoc performBlock:^{
            for (NSDictionary *newObjectDict in objects) {
                 Compatibility *object = [NSEntityDescription insertNewObjectForEntityForName:entityName inManagedObjectContext:tempMoc];
                 object.prod1 = newObjectDict[@"prod1"];
                 object.prod2 = newObjectDict[@"prod2"];
                 object.prod3 = newObjectDict[@"prod3"];
                 object.region = newObjectDict[@"region"];
                 object.result = newObjectDict[@"result"];
                 NSLog(@"%@", object);

VBA Looping through a dynamically generated string array (type mismatch)

it should still fix some issue It sounds like your main challenge is how to loop through your string array. The following code shows how to do this:
   For i = LBound(test_arr) To UBound(test_arr)
      'your logic here
      'you would refer to an element like this test_arr(i)

Save question when no answer is available for that question (new question) in QnA Maker Knowledge Base

it helps some times I was able to achieve something similar using a SharePoint list.
const csomapi = require('../node_modules/csom-node');
settings = require('../settings').settings;

// Set CSOM settings
csomapi.setLoaderOptions({url: settings.siteurl});
// If no answers were returned from QnA Maker, reply with help.
            } else {
                await context.sendActivity("Er sorry, I don't seem to have an answer.");
                var response = context.activity.text;
                var authCtx = new AuthenticationContext(settings.siteurl);
                authCtx.acquireTokenForApp(settings.clientId, settings.clientSecret, function (err, data) {

                    var ctx = new SP.ClientContext("/sites/yoursite");  //set root web
                    authCtx.setAuthenticationCookie(ctx);  //authenticate
                        var web = ctx.get_web();
                        var list = web.get_lists().getByTitle('YourList');
                        var creationInfo = new SP.ListItemCreationInformation();
                        var listItem = list.addItem(creationInfo);
                        listItem.set_item('Title', response);
