Write a program that reads an integer value n from the keyboard and then sums the integers between 0 and n. Your program should be able to handle both positive and negative values of n and should write the sum to the output file sumitout.txt. Note that your sum should not actually include 0, since that does not affect the sum. Your program should open the file sumitout.txt for appending so that the file can record a series of runs.

This is a free form programming assignment where you are: Required to create a simple phone book application Asked to make a choice of appropriate data structure and implementation. Defend your selection and explain the efficiency of your program using Big(O) notation.You do not need to create data structures from scratch. You are free to use datastructures available in the standard template C++ library. For example std::stack<int> orstd::set<int> , std::maps<int,int>, etc. You have familiarity with these from your CodeStep by Step labs. You are not permitted to use simple arrays. SpecificationsCreate a phone book program that stores and manages contact information.Contact information is name and corresponding phone number. The program reads thisinformation for multiple contacts from a data file "contacts.txt" and saves them in asuitable data structure. Once the data is stored, it allows the user to display all contacts,add a single contact, remove a contact,...

I have a logical question in C programming- so given that- typedef int tile[2]; what does this mean tile tileArray[35];

Write a C++ Program using classes, functions (recursive and otherwise), arrays and other C++ commands for a friendly game of BlackJack (no bets), according to the rules in Wikipedia. The program would ask if the user wants to play a game and draw the cards. Depending on the drawn cards, the game would progres according to the rules. When the game ends, the program asks if the user wants to play again. You can use a Joker of any card type as a Wild Card valued up to the highest rated card in the deck needed to complete the card hand, if applicable; if not, the player decides the value of the Joker for their card hard (user's hand or program' hand). The game will keep running as long as the user states so.

ONLY IN C++ Upvote for correct program and working code/output. Downvote if it's copied from somewhere else. Thank You. Create a program which can test the validity of propositional logic. Remember, a propositional logical statement is invalid should you find any combination of input where the PROPOSITIONAL statements are ALL true, while the CONCLUSION statement is false. Propositional Statements: If someone has a rocket, that implies they’re an astronaut. If someone is an astronaut, that implies they’re highly trained. If someone is highly trained, that implies they’re educated. Conclusion Statement: A person is educated, that implies they have a rocket. Your output should declare the statement to either be valid or invalid. If it’s invalid, it needs to state which combination of inputs yielded the statement invalid. MAKE SURE IT POINTS OUT EVERY TIME THE STATEMENT IS INVALID IF IT IS INDEED INVALID. C++ ONLY! Thank you.

Develop an algorithm and write a C++ program that counts the letter occurrence in the string; make sure you use call by reference to the array of a class with letter and count as private member attributes when return from parse function. For the class member methods, provide the public accessor and modifier as well as print functions for the private member attributes. Write a test program that reads a C-string and displays the number of letters [a-z] and number of numbers [0-9] in the string. In addition to that, you need to output the histogram of the letter and count array. Here is a sample run of the program: <Output> Enter a string: 2023 is coming The number of letters in 2023 is coming is 8 The number of numbers in 2023 is coming is 4 ---- Histogram ---- Char Count 0 1 2 2 3 1 c 1 g 1 i 2 m 1 n 1 /* not a completed output */ <End Output>
