Suppose you are using a jQuery animation to make an element change color when the user clicks on it, and you also want to execute a function as soon as the animation finishes running. How can you do this? a. Pass the function in as the first argument to theanimate()method called on the element. b. Use anif elseblock with thehasClass()method to determine when to call the function. c. Pass the function in as the final argument to theanimate()method called on the element. d. You cannot accomplish this using jQuery commands.

Assume that class ArrayStack has been defined using the implementation in your textbook. Assume also that you start with the following code fragment: ArrayStack intStack; int data; intStack.push (4); #Statement A intStack.push (3); # Statement B intStack.push (2); # Statement C intStack.push (1); #Statement D Where should the statements: data intStack.peek): intStack.pop(): cout << data << endl; be placed into the code above to produce the following output: 4 The statements will be inserted as a group. Choose all locations required to produce the output.
Description:Create JFrame application called Dictionary.Set up three one-dimensional arrays to contain the equivalent English andother-language-of-your-choice nouns, and the images of those objects.Typing a word in one of the languages and hitting the appropriate buttonshould produce the translation and display the picture of that object. Makesure you check to see whether the word is in the dictionary. If it is not,display a message "Word is not found".Three arrays will be of equal length (array_length).The program should work for different array_length values. Test andupload for array_length = 10.Requirements: This project requires typing a word in one of the languages. So, theprogram should be interactive. The word search should be case-insensitive. Three arrays must be declared: two String arrays for words in twolanguages and the third array for pictures files names. List of words in dictionary should be displayed for user With arrays, use for or enhanced for loop. Enhanced for…
