   scanf("%d", &position);
 
   printf("Enter the value to insert\n");
   scanf("%d", &value);
 
   for (c = n - 1; c >= position - 1; c--)
      array[c+1] = array[c];
 
   array[position-1] = value;

let array = ["Chicago", "Los Angeles", "Calgary", "Seattle", ] // print the array console.log(array) //Adding a new item in an array without touching the actual array array.push('New Item') < variable_name > .push( < What you want to add > ) //How many items does the array have? console.log("This array has", array.length, "things in it")

let chocholates = ['Mars', 'BarOne', 'Tex']; let chips = ['Doritos', 'Lays', 'Simba']; let sweets = ['JellyTots']; let snacks = []; snacks.concat(chocholates); // snacks will now be ['Mars', 'BarOne', 'Tex'] // Similarly if we left the snacks array empty and used the following snacks.concat(chocolates, chips, sweets); //This would return the snacks array with all other arrays combined together // ['Mars', 'BarOne', 'Tex', 'Doritos', 'Lays', 'Simba', 'JellyTots']

// A better solution would be to use an ArrayList which can grow as you need it. // The method ArrayList.toArray( T[] a ) // gives you back your array if you need it in this form. List<String> where = new ArrayList<String>(); where.add(element); where.add(element); // If you need to convert it to a simple array... String[] simpleArray = new String[ where.size() ]; where.toArray( simpleArray );

const myArray = ['hello', 'world']; // add an element to the end of the array myArray.push('foo'); // ['hello', 'world', 'foo'] // add an element to the front of the array myArray.unshift('bar'); // ['bar', 'hello', 'world', 'foo'] // add an element at an index of your choice // the first value is the index you want to add at // the second value is how many you want to delete (0 in this case) // the third value is the value you want to insert myArray.splice(2, 0, 'there'); // ['bar', 'hello', 'there', 'world', 'foo']
