- 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.arrow_forwardBy implementing the concepts of Classes and Objects, write a C++ program that determines the slope of a line from the coordinates, P(x,y), of the 2 points. The coordinates of the 2 points: P1 (x1, y1) and P2 (x2, y2) are to he entered from the keyboard. The slope, m, of the line is computed as: m=(y2-y1/x2-x1) Accomplish the following for the given class diagram: 1.) Create the class implementation using C++ 2.) Using the constructor, create 2 objects, P1 and P2, from class Point and store them in the heap memory. 3.) Implement the functions of the 2 objects. NOTE: The member function setXY is used to enter the values of x and y from the keyboard. Sample input/output display: Enter the coordinates of the 1st point (x1 y1): 1 1 Enter the coordinates of the 2nd point (x2 y2): 5 4 The slope of the line, m=0.75arrow_forwardplease answer with proper explanation and step by step solution. i need code in c++ Using the sample BUBBLESORT program given in class do the following: Print out the original unsorted data Print out the data sorted (ascending) Print out the data sorted (descending) Print out the Maximum and Minimum and the range Print out the median Print out the mode Print out any data having a frequency greater than 3 Print out the standard deviation Sample output: Unsorted List: 9 8 1 6 12 3 5 4 3 6 1 3 6 6 Sorted List: 1 1 3 3 3 4 5 6 6 6 6 8 9 12 (ascending) Sorted List: 12 9 8 6 6 6 6 5 4 3 3 3 1 1 Maximum: 12 Minimum: 1 Range: 11 Median: 5.5 Mode: 6 Frequency: 6 occurs 4 times 3 occurs 3 times Do NOT use files…I should be able to enter UP TO 15 values and have the program work. BE sure that your program covers ALL cases of the median and mode as discussed in class!!!!arrow_forward
- Write a C++ program for the following. In each plastic container of Pez candy, the colors are stored in random order. Your little brother only likes the yellow ones, so he painstakingly takes out all of the candies, one at a time, eats the yellow ones, and keeps the others in order so he can return them to the container in exactly the same order as before, minus the yellow candies, of course. Write a program to simulate this process. You must use Nyhoff's stack class; other solutions including the use of the STL stack class are unacceptable. Assume that the candies are denoted as Y for yellow, B for blue, R for red, O for orange. Your program is to query the user for ten letters (representing ten Pez candies), and after using appropriate stack operations, display the contents of the container minus the yellow candies. The order in which the letters are entered is the order that they were removed from the Pez container. When your answer is displayed the results must be in the same…arrow_forwardWrite this code in any language Python, Java or C++ and complete the code and make sure it runs.arrow_forwardWrite a function in C++ that accepts a student’s final exam grade (worth 40 points) and number of completed projects (each worth 10 points) and returns the calculated final grade (out of 100 points) to the main method.arrow_forward
