Programing Language: C++. Please do not use a string varible and add notes for understanding.
6.13: Word CountWrite a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a “word” to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.
Input Notes:There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read.
Output Notes (Prompts and Labels): The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt.
The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the…

- (Intro to Java) Only use while loop or for loop. DO NOT use try loop! DO NOT use null. Avoid using breaks! Tracking Customers This program will read in a series of names, along with an associated gender, from an input file of unknown length. The program uses a while loop to read in each name from the file by using the hasNextLine() method from the Scanner class. Please use a while loop for practice, although you could also write this assignment using a for loop to read from the file. As you read in each name, you will store it in an array, along with a title (Mr. or Ms. or Mx.) dependent on the stated gender.

The words should be separated by spaces. When the sentence is output, it should start witha capital letter and end with a period. The program should generate 10 sentences and output them to a text box. The arrays should be filled as follows:The article array should contain the articles "the", "a", "one", "some" and "any";The noun array should contain the nouns "boy", "girl", "dog", "town", "car";The verb array should contain the past tense verbs "drove", "jumped", "ran", "walked" and "skipped";The preposition array should contain the preposotions "to", "from", "over", "under" and "on";arrow_forward(Sort three numbers) Write the following function to display three numbers in increasing order: def displaySortedNumbers(num1, num2, num3): Write a test program that prompts the user to enter three numbers and invokes the function to display them in increasing order.
