Create a program that makes a grocery list.
You will need an array of strings.
You don’t know how many items will be on your list.
Simple problem: User tells you how many items, then tells you the items. You display the items for the user.
More complex problem: User tells you how many items, then tells you the items.
You display the items for the user. At the end of the program, write the grocery list to a text file called grocery.txt.
Even more complex problem: If grocery.txt exists, read it into an array and display to the user.
User then tells you how many more items, and then tells you the items. You display all the items for the user.
At the end of the program, write the grocery list to a text file called grocery.txt.
Start with the simple program, move toward the complex one.

A regular expression (shortened as regex or regexp; also referred to as rational expression) is a sequence of characters that specifies a search pattern. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation.
using regex create a python program to verify the string having each word start from 'f'? It should return True otherwise false.

- 2) Design NFA that accepts the set of strings over (a, b} such that there should be at least one substring which starts and ends with a b and the number of symbols between these two b's is divisible by 4. Example: abababaaaababab, babbaa (since 0 is divisible by 4), ababababbaaarrow_forwardC programming language questionarrow_forwardC++ Memory Game Children often play a memory game in which a deck of cards containing matching pairs is used. The cards are shuffled and placed face down on a table. The players take turns and select two cards at a time. If both cards match, they are left face up; otherwise, the cards are placed face down at the same positions. Once the players choose their pair, they can see the board for some time period and attempt to memorize the configuration of cards. They can then use their memory to select the next pair of cards when it is their turn. The game continues until all the cards are face up. Assume that there are two players and to make the game interesting, keep track of how many correct matches each player makes. When all the cards are turned face up, the player with the most matches is the winner. Write a program to play the memory game. Use a two-dimensional array of 4 rows and 4 columns for a deck of 16 cards with 8 matching pairs. You can use numbers 1 to 8 to mark the cards.…arrow_forward

Please do NOT use pointers, please! :) The Collatz conjecture is a conjecture in mathematics named after Lothar Collatz, who first proposed it in 1937. The conjecture is also known as the 3n + 1 conjecture, the Ulam conjecture (after Stanisław Ulam), Kakutani’s problem (after Shizuo Kakutani), the Thwaites conjecture (after Bryan Thwaites), Hasse’s algorithm (after Helmut Hasse), or the Syracuse problem; the sequence of numbers involved is referred to as the hailstone sequence or hailstone numbers (because the values are usually subject to multiple descents and ascents like hailstones in a cloud), or as wondrous numbers.

Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt. Extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day. Make the function return true (t) instead of the last thing it evaluates, to avoid seeing the message printed more than once.arrow_forwardWhat causes Strings to be immutable?arrow_forward
- C Program Removing Elements in an Array Make a program that creates an array by asking the size n of the array and n integer inputs. Example: Input size of array: 5 Array elements: 1 2 3 4 5 After creating the array, you need to prompt the user again to pick m number of elements to remove. If the input is invalid, prompt the user to try again. An input is invalid if it meets either one of these criteria: Greater than size n of the array Negative number Example: Number of elements to remove: -2 Invalid number. Try again: 3 After a valid input, prompt the user for the valid indices to remove. An index is valid if it is within the range of the array size. Output the array elements after a valid index input and consider the new size of the array after. Example: Index (1): 2 Array elements: 1 2 4 5 Index (2): 4 Invalid index! Try again. Index (2): 0 Array elements: 2 4 5 Index (3): 2 Array elements: 2 4 After everything, print FINISHED! Input 1.
