C++ PROGRAM Exercise 1: Average Age of Adults Write a program that computes the average age of adults in a sample population. The program prompts the user to enter the size of the population and then using a for loop, it shall prompt the user for the age of every person in the population. The program shall compute the average age of adults only. Produce output as shown in the sample input/output. Note: an adult is a person whose age is 2 18. Sample input/output: Enter size of population sample : 6 Enter age of person # 1: 20 Enter age of person # 2: 10 Enter age of person # 3: 15 Enter age of person # 4: 24 Enter age of person # 5: 19 Enter age of person # 6: 18 There are 4 adults in the population sample. The average age of adults is: 20.25

C++ programming Write a program that reads the grades of 3 students in three different courses and displays the average grade of each student in these three courses, as well as the average grade of all students. You can use any loop method of your preference. (Hint: This is a nested loop technique)
C++ Coding: Nested Loops Create a constant DIM. Set DIM to 7, and use a nested loop to display the following square matrix output. Output Example: - - - X - - -- - - X - - -- - - X - - -X X X O X X X- - - X - - -- - - X - - -- - - X - - -

//for loop practice/*create a program, called aveRaceTime.cpp, for runners that wish to know their average race time.ask the user how many races they ran, and use their input in your for loop,for the limit on the number of loops (for example, if the user inputs three,that means your for loop should run three times.) Each time the loop runs, itwill ask the user what their race time was in minutes. Keep a running total ofall of the race times added together. After the loop, compute the user's average racetime, and display it in a sentence. Format the average time so it always shows two decimal points.
This program in C++ obtains a series of letter grades as input from a user. The program should calculate and output the total grade points and the grade point average (note: you may have to track the total number of inputs and the grade points to calculate the grade point average). The algorithm should execute 3 times for testing purposes. Use the appropriate loop for the main structure of the program that will stop accepting letter grades when the user inputs X. Also, choose the appropriate selection statement to convert the letter grade to the correct grade points. Additional Requirements: • Use appropriate data types and variable names throughout the code. • Use constants appropriately. • Adhere to the style guidelines for the class • Adhere to proper style & structure guidelines for the class • The goal of this assignment is to demonstrate the use of selection and repetition statements, so please be careful in choosing the correct constructs.

Write a program that calculates the balance of a savings account at the end of a period of time. It should ask the user for the annual interest rate, the starting balance, and the number of months that have passed since the account was established. A loop should then iterate once for every month, performing the following: A) Ask the user for the amount deposited into the account during the month. (Do not accept negative numbers.) This amount should be added to the balance. B) Ask the user for the amount withdrawn from the account during the month. (Do not accept negative numbers.) This amount should be subtracted from the balance. C) Calculate the monthly interest. The monthly interest rate is the annual interest rate divided by twelve. Multiply the monthly interest rate by the balance, and add the result to the balance. After the last iteration, the program should display the ending balance, the total amount of deposits, the total amount of withdrawals, and the total interest earned.
python Write a program that runs like a cashier in a store. The program should use a while loop and prompt for the quantity and unit price of each item being purchased. The number of different items cannot be known in advance so the loop should continue until zero is entered for the quantity. A subtotal should be printed after each item's data has been rung up. See Sample Output. When the loop ends the program should report the number of different itemspurchased and the total amount due. SAMPLE OUTPUT: Enter item quantity or zero to quit 2 Enter unit price of item 2.50 Subtotal is $5.00 Enter item quantity or zero to quit 1 Enter unit price of item 7.99 Subtotal is $7.99 Enter item quantity or zero to quit 3 Enter unit price of item 2.39 Subtotal is $7.17 Enter item quantity or zero to quit 0 You purchased 3 different items Please pay $20.16
C++ Write a program that prompts the user for a positive integer. Validate the input and do not accept a negative number. Use a while loop to find the sum of all odd digits of the number. Sample run of program: Enter a positive integer: > -237 Invalid input! Try again: > 237
