1) Guessing Game in Matlab . When the program starts, a random whole number , n , is selected where : n >=1 and n < = 200 . The user enter "a guess" and the program displays * " higher " if the guess is less n * " lower " if the guess is great than n * " correct " if the guess is equal to n . The game continues until the user enters a correct guess and the program quits . When the program quits , the total number of guesses is displayed as the score. 2) in 100 words explain how sections of the code function or explains how your program works.
Please note only looking for the solution to problem 2 but problem 1 is needed to help you understand what is being asked *must be created using Visual Studio and C# Problem1 Word Counter Create an application with a method that accepts a string as an argument and returns the number of words it contains. For instance, if the argument is "Four score and seven years ago," the method should return the number 6. The application should let the user enter a string, and then it should pass the string to the method. The number of words in the string should be displayed. Average Number of Letters Problem2 Modify the program you wrote for Problem 1 (Word Counter) so it also displays the average number of letters in each word.
Exercise 4: Selection and loop statements A certain professor gives 5-point quizzes that are graded on the scale 5-A, 4-B, 3-C, 2-D, 1- F, 0-F. Write a program that accepts a quiz score as an input and prints out the corresponding grade. The input data must be a float numbers and between 0 and 5 Example Input : Quiz score: 3 Output: The grade is C. Exercise 4 Write an improved version of the future value program from Chapter 2. Your program will prompt the user for the amount of the investment, the annualized interest rate, and the number of years of the investment. The program will then output a nicely formatted table that tracks the value of the investment year by year. Your output might look something like this:
Microwaves / Radio Waves If a scientist knows the wavelength of an electromagnetic wave she can determine what type of radiation it is. Write a program that asks for the wavelength in meters of an electromagnetic wave and then displays what that wave is according to the following chart. (For example, a wave with a wavelength of 1E-10 meters would be an X-ray.) 1x 10-11 1 x 10-8 4 x 10-7 7x 10-7 1x 10-3 1 x 10-2 Gamma Rays. X Rays Ultraviolet Visible Light Infrared

C++ Visual Studio Modify the following program so it displays a menu allowing the user to select an addition, subtraction, multiplication, or division problem. The final selection on the menu should let the user quit the program. After the user has finished the math problem, the program should display the menu again. This process is repeated until the user chooses to quit the program. Input Validation: If the user selects an item not on the menu, display an error message and display the menu again. Code: #include <iostream>#include <cstdlib>#include <ctime>#include <conio.h> using namespace std; int main() {srand(static_cast<unsigned int>(time(nullptr))); while (true) {// Generate two random numbers.int num1 = rand() % 1000;int num2 = rand() % 1000; // Display the problem.cout << "Solve the following math problem:" << endl;cout << num1 << " + " << num2 << endl; // Wait for user input to reveal the answer.cout <<…
Problem definition: A college wants to know how well its students did on an exam. The following program summarizes the results. The program asks a user to enter the results pass (1) or fail (2) for 10 students. It displays the number of passed and the number of failed. It displays a message "Raise error" if the number of passes is more than 8 You are asked to identify statement with syntax errors by selecting them as wrong and the correct statements as right
Learning Objectives: Python Programming Use loop over a stringReplace characters within a stringFunction (declaration and call)Write code in modular formInstructions Create a function only_chars that takes the line of text and returns the text line excluding the spaces, periods, exclamation points, or commas. Create a program that will read the input line, use the function, and then print the line, without spaces, periods, exclamation marks, or commas and their length. Ex: If the input is: Listen, Mr. Jones, calm down. the output is: ListenMrJonescalmdown21Do not forget if __name__ == "__main__" section!
Question 18 Guessing Game Code a solution for the following problem. Post your program in the textbox below. (NOTE: Indenting matters.) • Hard-code an integer variable valid value from 1 to 10. Ask the user to guess your whole number and input that number. - Then compare the user's input to your literal number ani tell the user how they compare, is it greater than, less than or equal to each other. Extra: Send an error message if the value entered is not between 1 and 10. Edit View Insert Format Tools Table Ev Ev To E v V O Paragraph v BIU A ev T? v 12pt v
Without these three things, a network won't work as well or as efficiently as it could. Could you explain why you chose to do this?
Sentence Statistics Create a program that can tell a user how many times a particular character appears in text input. Your program will analyze the input, then prompt the user to enter characters to get stats. When the user types 'Q' the program will exit. Enter text input to analyze: The quick brown fox jumped over the lazy dog. What character do you want stats on? a The character a appears 1 times. What character do you want stats on? e The character e appears 4 times. What character do you want stats on? z The character z appears 1 times. What character do you want stats on? Q Goodbye! Analyzing the sentence We've provided starter code in main.cc to get input from the user. Now you need to analyze it. You can use a std::map to store information about each character and the number of times it appears in the input. A std::map maps keys of one type to values of another type. For this problem, you'll want to map from a letter to the number of times that letter appears. In C++, the char…
