Text-based adventure game: Pretend you are creating a text-based adventure game. At different points in the game, you want the user to select to fight, run, or hide from certain enemies. Modify the application below (week3.py) so that the selection variable is sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. You will need to add an if statement in the choice() function to make the correct selection.
Assignment #2 Instructions: Through this programming assignment, the students will learn to do the following: Learn to work with command line options and arguments Gain more experience with Makefiles Gain more experience with Unix Learn to use some of the available math funtions available with C Usage: mortgagepmt [-s] -r rate [-d downpayment] price In this assignment, you are asked to perform the mortgage payment calculation. All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate…

A struct to store a single playing card is as follows: struct card { char suit; char kind; }; The valid suits are 'S', 'H', 'D' and 'C', while the valid kinds are 'A', '2', '3', '4', '5', '6', '7', '8', '9', 'T', 'J', 'Q', and 'K'. A poker hand can be stored as an array of five struct cards. A flush is a hand that contains five cards, all of the same suit. Write a function that returns 1, if the poker hand passed to it has five cards of the same suit, and 0 otherwise. int isFlush(struct card hand[]); int isFlush(struct card hand[]) {

Perform a Profile of your Dec2Hex function. Write a function that takes a timedate object as a parameter andcalculates the number of years from NOW to the time in the timedateobject.
C++ Vector iteration: Sum of excess. Vector testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.
