Concept explainers

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

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…
add a menu that you design which includes these features: Ability for a user to input a set of grades into a vector. Make sure only integers between 0 and 100 are used. Cout the vector onto the screen with grades separated by spaces and starting with, "Original user vector: " Output the average grade. Ability to sort the user-inputted vector from low to high or high to low. Cout the new sorted vector onto the screen with grades separated by spaces and starting with, "Grades sorted vector: " Using the binary search method (not the linear search method), add the ability to find a user selected grade and change it.
