- Write a program in C++ using arrays, C-trings, classes, and libraries. Write a program to handle a user's rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc.). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu — don't force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don't forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the…Write a program in C++ that can perform encryption and decryption using an arbitrary substitution cipher. In this case, the encrpyion array is a random shuffling of the letters in the alphabet. Your program should generate a random encryption array, its corresponding decryption array, and use these to encode and decode the message.Please Answer in C++ language only Today the chef decided to cook some tasty dishes from the ingredients in his kitchen. There is an NN of components, represented by the strings S1,S2, .... SN. The chef took all the ingredients, put them in a cauldron and mixed them. In the cauldron, the letters of the strings representing the ingredients are completely shuffled, so that each letter appears in the cauldron as many times as it has appeared in all the strings combined; now the cook can take out one letter from the cauldron at will (if that letter appears in the cauldron more than once, it can be taken out that many times) and use it in a dish. Complete Food is a "chef" chain. Help the chef find the maximum number of complete meals he can make! Input 1 5 codechef chefcode fehcedoc cceeohfd codechef Output 5
- Write a program in C that carries out simple mathematical operations entered as a command-line strings named "calculator". Implementation:You will receive a single prefix arithmetic expression in text via argv[1]. You can assume the operands and operators will be space-separated. Test for possibility (i.e. no dividing by zero) and is correctly formatted (i.e. has exactly two operands).Your operands are: Your operators are: Your errors are: zero plus Error: not an operator: <text> one minus Error: not an operand: <text> two multiply Error: not enough operands three divide Error: too many elements four Error: divide by zero five six seven eight…Write a c++ program that determines whether or not a string of alphanumeric characters is a palindrome. Ignore any whitespace characters or punctuation when processing the string. You will be required to demonstrate pointer math and dereferencing. You will be required to separate your interface from your implementation; you must have a header file (.h) for your interface, and a source file (.cpp) for your implementation. Be sure to perform data validation on your input to prevent buffer overflows. Your code should present the user with prompts similar to the following: (image included) Here are some example palindromes you can test with: Mr. Owl ate my metal wormDo geese see God?Was it a car or a cat I saw?Murder for a jar of red rumA nut for a jar of tunaGo hang a salami, I'm a lasagna hog!Give an example of a C++ code snippet that performs some operation on an array (e.g. sort, search, fill, modify, etc). You should have at least six lines of executable C++ code and your code should be different than anyone else's. Then state the runtime of your code snippet, but don't state what the algorithm is.
- Write a C++ program. Only use string, vector and iterator types from STL for solving these two problems. You can also use a math library. Q2: Design a game that mimics Wordle. Design the code by using functions as much as you can. You do not need to design a graphical interface as shown on the website. This assignment is about designing the underlying logic. Hardcode a set of valid dictionary words in your program. At the end of each try, you can output the text as shown in their example below (i.e., "The letter W is in the word and in the correct spot."): W EARY The letter W is in the word and in the correct spot. ILLS The letter I is in the word but in the wrong spot. V AGUE The letter U is not in the word in any spot.In c++ , perform data searching using linear and binary search. ( Drop code in words , explain the code and drop the screenshot of output as well )Write a program in C language that implements a simple hand calculator. The followings arithmetic functions are available on the calculator: addition, subtraction, multiplication, division, cosine, sine and tangent. The result of the function must have the same number of digits of precision as the highest precision operand of the function. An example of the program behavior is shown below. > 8.91 + 1 = 9.91 > 9.61*3.11 = 29.8871 > cos(3.14152759) = 0.99849715
