Step 1:Create an array named UserTicket to hold each of the user’s lotto number

Question

Step 1:Create an array named UserTicket to hold each of the user’s lotto number selections.Create an array named WinningNums to hold the winning lotto numbers.Step 2:Display the following menu:LITTLETON CITY LOTTO MODEL:---------------------------1) Play Lottoq) Quit ProgramPlease make a selection:-If the selection is 1:a. First ask the user their name and store it in an appropriate variable.b. Next, call a function named getLottoPicks that asks the user to enter their 7 lotto number picks (selections) for the week. Each of the user’s lotto picks should be stored in the UserTicket array. The lotto does NOT have duplicate numbers in it. Find a way to not allow duplicate numbers to be picked by the user. You will create another function called NoDuplicates that checks to see if the user’s selection is already in the UserTicket array. If the user enters a number already in the array, ask them to enter another number until they enter one that is not a duplicate. This means the UserTicket array should contain no duplicate numbers.c. Next, call a function named GenWinNums that randomly generates the winning lotto numbers for the week based on the rules stated above and stores the winning lotto numbers in the WinningNums array (so you are going to fill the WinningNums array with random numbers between 1 and 40). Do not allow this function to generate duplicate winning numbers. Use the NoDuplicates function to check for duplicates in the WinningNums array. Note: do NOT call the srand function in GenWinNums (the srand is done the main ONLY).d. The next step is to check the user’s lotto ticket (represented by the UserTicket array) to see if they have won any prizes in the Lotto game. Check each number the UserTicket array to see if that number is in the WinningNums array and count how many numbers are matched.
