[SOLVED] Programming assignment-1 cs200

Question 1 [25]:
A. Write a swap () function that only takes pointers to two integer variables as
parameters and swaps the values in those variables using the pointers without
creating any extra variables. The swapped values are displayed fromthe main(). [5]B. Write a program that will take a char array as an input, and it reverses the positionsof the char elements in the array. You are not allowed to make a newarray. Usethebracket notation of arrays for this question eg: arr[j + k]. [5]Example:
Input: [ ‘C’, ‘S’, ‘2’, ‘0’, ‘0’]
Output: [‘0’, ‘0’, ‘2’, ‘S’, ‘C’]C. Write a program that will ask the user to enter a two integer arrays of variablesize(this means that the user can tell the program the size of each array), and thencomputes the intersection and union of those arrays. Note: the arrays can be of different lengths and the intersection/union shouldhaveunique elements in sorted order. Use pointer notation of arrays for this question. Eg: *(arr+1) [10]Output Example:
Enter size of array 1: 2
Element 0, array 1: 10
Element 1, array 1: 9
Enter size of array 2: 5
Element 0, array 2: 9
Element 1, array 2: 8
Element 2, array 2: 3
Element 3, array 2: 3
Element 4, array 2: 10
Union: {3, 8, 9 ,10}
Intersection: {9, 10}D. Write a function named searchInsertPos () that takes in three arguments: a sortedarray, size of the array, and an integer number. It should return the position wherethe integer value is found. In case the number does not exist in that array it shouldreturn the index where it should have been if it were present in this sorted array. Usepointer notation of arrays for this question. [5]Question 2 [25]:
A. Write a function isPalindromeDelete () that will take a string containing only
alphanumeric characters that are in lowercase (if you think your logic requires youtouse more than one argument, please go ahead). Your task is to see if the stringbecomes a palindrome if only one character is removed from anywhere in thestring.[12]Example:
Input: “pop”, Output: true
Input: “pops”, Output: true
Input: “acde”, Output: false
Input: “”, Output: trueB. In this task you will implement a function targetSum (). Argument: a sorted integer
array, size of the array, and a target integer value. You have to find all combinationsof two elements in the sorted array which sum up to the target value. When found, add the combinations into an array, and print the array. In the case where thereismore than one combination, you may use the number 999 as a separator for thetwoor more combinations in the output array. Note: You are not allowed to use morethan one loop. Use pointer notation of arrays to do this question. [13]
Input: [2, 4, 6, 9, 11], target = 11Output: [2, 9]
Input: [-10, 10, 10, 20, 30, 40], target = 20
Output: [-10, 30, 999, 10, 10]
Input: [-1, 4, 6, 9, 10], target = 0
Output: []Question 3 [95]:
In this task, you will implement a restaurant system using structs (using the dot notation). There is a single person managing a new restaurant and several potential customers will
come to the restaurant.Initially, there will be a main menu displayed on the console to enter either of the twomodes:
customer or owner. Main Menu [3]:  Press 1 for customer mode
 Press 2 for owner mode
 Press 3 to exit programIf customer is selected, the following options should be available for the customers[2]:  Press 1 for new customer  Press 2 for current customerThe details of what the above selections would do is specified below:
1. New customer  The customer is prompted to enter their name (assume every person at the
restaurant has a different name) [2]  The customer is asked to select a seat position to be seated and after successful
seating, the customer menu is displayed. The criteria for successful seating is statedbelow [3]  Select seat [2+2+2+2+2]:o There is a single row of 10 seats available, each empty seat depictedwithan‘o’ o The customer will select the numbered seat they wish to sit at, and theoccupied seat will then turn ‘x’ (the size of the seats array will remain thesame)o A customer may mistakenly try to sit in an already occupied seat andyoushould make sure that isn’t possible. (report the exact probleme.g. Error: seat
taken, choose another seat)
o You should also make sure that whatever seat the customer chooses isn’t tothe immediate left or immediate right of an occupied seat, keeping in viewsocial distancing rules. o The customer should be asked to select a different seat until a successful
seating is done2. Current customer (already seated)  they enter their name and if the named person is present in any of the seats, thecustomer menu is displayed, otherwise an error is displayed to show this personisnot currently at the restaurant [3]
Customer Menu [2]
Press 1 to View food menu
Press 2 to Place order
Press 3 to View order
Press 4 to Pay bill
Press 5 to Leave
Press 6 to Return to Main menuThe details of what should happen when any of the options are selected are
explained as follows:
1. View food menu [10]:  This will simply display the current menu of the restaurant in the followingformat: (Serial no Dish name Price)
Hint: There should be an array of struct defined for menu items. There can beat
most 10 items on the menu. This would be the same for both owner and customer.  At initialization, the menu should have 4 items already (of your choice) (Thisis to allow space for adding more food items later)2. Place order [10]:  The customer will place their order by entering the serial number of thefoodwhich will place the order (food item name) on the list for the owner toviewaswell.  For simplicity’s sake, assume every customer only orders one item3. View order [5]:  This will display the name of the item of food ordered by the customer4. Pay bill [8 + 2]:  If a person selects to pay the bill, the person’s order is removed fromthelist of current orders kept by the restaurant and the customer is
regarded as being served by the restaurant and the amount of thebill isadded to the earnings of the restaurant.  Make sure that a person is not able to pay if their order was empty5. Leave [5]:  A customer must only be able to leave if they have no amount due
 Their seat should be vacated after they leave
Menu
1. Apple Pie $ 11.00
2. French Fries $8.00
3. Lasagna $24.00
4. Chop suey $15.00If owner mode is selected from the Main Menu, the following owner menu should bedisplayed on the console:
Owner Menu [3]
Press 1 to Update food menu
Press 2 to View food menu
Press 3 to View number of customers served
Press 4 to View orders received (names of food items)
Press 5 to Amount earned
Press 6 to Offer discount
Press 7 to Return to Main menuThe details of what should happen when any of the options are selected are explainedasfollows:
a. Update food menu [10]:  The owner would like to make the small café bigger so they would liketoaddmore food items to the menu but does not intend to get rid of anyitemonce added on the menu card.  The popularity of a dish may warrant changing its price so there shouldbeanoption to adjust the price of any item on the menu individually.  These two options should be displayed to the owner to select fromb. View number of customers served [2]:  This should simply display the total number of customers servedc. Orders received [5]:  The orders of customers who have not paid for their food yet are displayed Assume there are no more than 10 orders maded. Amount earned [5]:  This should display the total earnings the owner has made at the restaurante. Offer Discount [5]:  The owner would enter the percentage amount to offer discount whichwouldapply to all items on the restaurant menu.
