Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Complete the program to read the needed values from input, that the existing output statement(s) can use to output a short story.

Read the user the number of groups (minimum 6) • For each group: group name and the number of students minimum 10 are entered. • For each student in a group: grade should be entered, and grade category has to be computed and printed. • For each group, the number of student and percent ratio in each grade category should be computed and printed. • Finally, the program should print a summary report with the following details: 1. Number of groups. 2. Total number of students and percent ratio of students in each grade category in all groups. 3. The name of the best group which has the maximum percent of students in grade A category and these students percent ratio. 4. The name of the worst group which has the maximum percent of students in the grade F category and these students percent ratio. grade category А 90–100 % 80-89 % 70–79 % D 60-69 % F < 50 % ps; this program should not use array and only one main method
Homework write a program that will add the terms of an infinite geometric series. The program should read the first term (a) and the common ratio (r) for the series. It should the compute the sum in two ways: by formula (s=a/1-r), and by adding the individual terms until the answer agrees with the formula to 7 significant digits. The print the formula answer, the answer found by adding terms, and the number of terms that were added. Print the sums to at least ten places. Verify input with a while loop. Two real values are equal to n significant digits if the following condition is true: |a-b|<|a*10^-n| Wrong test - this won't work if r is very near one. Try a=2, r=.99999 With smaller values of r, it is asking for too much precision. With a=2,r=.99, it is getting 10 significant digits. HELP ME FIX CODE.

a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player's choice of either High or Low is compared to random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered "low". A number between 8 and 13 inclusive is "high". The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to: High Low Gane RULES 1 through 6_are lou Nunbers 8 through 13 are high Number ? is neither high or low You have 1000 points. Enter points to risk: 500 Predict (1=High, 0=Low): 0 Nunber is 4 You win. Play again? y You have 2808 points. b) Modify the application to…

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
Assignment 1/ Reset to Starter Code 2. Problem 2: Product ID Numbers Saved Problem Description In this second problem, you will build on and extend the program created while solving the first problem. You will be expected to isolate both the product id number and company number from the barcode number of the item to be purchased by the customer. Input You will receive (from the user) the following as input (in order): • The first and last name of the customer (e.g., Eric Poitras) • The item to be purchased, identified through a barcode number (e.g., 1909238092) • The cost of the item to be purchased by the customer (e.g., 8.50) • The cash amount given by the customer (e.g., 10.00) Processing 1. Extract the product id and company id numbers 2. Print the data stored in each variable in the corresponding format Output 1. Customer (Last, First): {LAST} {FIRST} 2. Item Number (Product, Company): {PRODUCT} {COMPANY} 3. Item Cost: (COST} 4. Cast Amount: {CASH} Examples Input Output Eric…
3. The formula for determining compound interest is: A represents the amount to earn; P is the principle that is initially invested; r is the interest rate earned; n is the number of times the interest is compounded; and t is the number of time periods for the investment. Write a program that prompts the user to enter P, r, n and t. The program should output the amount earned on the investment. 4. Look up the Pythagorean theorem if you are not already familiar with it. Use the following formula to solve for c in the formula: c = √a2 + b2. Use the proper functions from the cmath header file. Be sure to output the result.l
