Code using c++ 2. Solving a Person's Loneliness by CodeChum Admin It's been 1,245 years and our sole Person is getting lonelier each day. This Person definitely needs a partner! Thus, we need to update our Person's design to have a gender as well and there shall be male and female! Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. Your task is to first update the struct Person so that it can have a gender as well. For this program, we shall represent a gender with a single character: 'M' for male and 'F' for female. Then, create a Person, take in an integer user input and a character user input, and then set them as the Person's age and gender respectively. Finally, call the displayPerson() function and pass that Person you created. Input 1. The age of the Person 2.…
For C++ how do I write a program that plays a word game with the user? The program asks the user to enter the following: His or her name, age, college, profession, type of animal, and a pet's name. The inputs are then inserted into a story as follows:There once was a person named (NAME) who lived in (CITY). At the age of (AGE), (NAME) went to college at (COLLEGE). (NAME) graduated and went to work as a (PROFESSION). Then, (NAME) adopted a(n) (ANIMAL) named (PETNAME). They both lived happily ever after!
Solve the problem in C++ (Assign grades) Write a program that reads student scores, gets the best score, and then assigns grades based on the following scheme: Grade is A if score is >= best – 10; Grade is B if score is >= best – 20; Grade is C if score is >= best – 30; Grade is D if score is >= best – 40; Grade is F otherwise. The program prompts the user to enter the total number of students, then prompts the user to enter all of the scores, and concludes by displaying the grades. Sample Run Enter the number of students: 4 Enter 4 scores: 40 55 70 58 Student 0 score is 40 and grade is C Student 1 score is 55 and grade is B Student 2 score is 70 and grade is A Student 3 score is 58 and grade is B

1. Write a program in C that will read a number as input. Check whether the number is prime number or not. Hint: A prime number cannot be divided by any other numbers without leaving a remainder. An example of a prime number is 13. It can only be divided by 1 and 13. Dividing a prime number by another number results in numbers left over e.g. 13 + 6 = 2 remainder 1 2. You are tasked to develop a C program that will generate a simple calculator using switch case statement. Hint: Program takes an arithmetic operator +, -, *, / and two operands from the user. Then, it performs the calculation on the two operands depending upon the operator entered by the user
C++ only Upvote for your own work and correct answer/ Downvote for copying the answer from a different website. It must be in C++ and it must be a working code. Thank You. Assignment: Create a C++ program that 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, which 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.

Write a C++ program Design and write a program that will accept a sentence as input, reverse the words and print the sentence out backwards. The individual words should not be reversed as we did in class. The words in the sentence should be in reverse order. Example Input: The movie was not very true to the book.Output: book the to true very not was movie The (NOTE: You may keep the period at the end if you want to.) Turn in your design (Flow Diagram) along with your code and screen shots. You can use a program like PowerPoint or some other drawing package for this or you can draw it by hand then take a picture and upload the picture along with your code and output.

i want the solution in C++ language solution should setup the midnight time to 0, and then write out all the possibilities that can take place in finding the difference between hours and minutes 4.7: Time Machine Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time (in hours, minutes, and a Boolean indicating AM or PM) and a future time (in hours, minutes, and a Boolean indicating AM or PM) and calculate the difference in minutes between the start and future time. A time is specified in your program with three variables: int hours, minutes; bool isAM; // You can also use a char, i.e. A or P for example, to represent 11:50 PM, you would store: hours = 11,minutes = 50, isAM = false or if using a char, hours = 11,minutes = 50, isAM = 'A' This means that you need six variables to store a start and future time.…
Write C assignment statements for the following: a. Assign a value of 0 to a variable called between if n is less than -k or greater than +k; otherwise, assign 1. b. Assign a value of 1 to a variable called divisor if digit is a divisor of num; otherwise, assign a value of 0. c. Assign a value of 1 to a variable called lowercase if ch is a lowercase letter; otherwise, assign a value of 0.
