Write a program that asks the user for a positive nonzero integer value. The program should use a loop (while loop) to get the sum of all the integers from 1 up to the number entered. For examples, if the user enters 50, the loop will find the sum of 1,2,3,4,….50.
Hint: You need two while loops here. One to make sure the user enters a positive number (keeps on asking the user for a number till he\she enters a positive nonzero number). And two to find the sum.
The distance a vehicle travels can be calculated as follows:
Distance = Speed * Time
For example, if a train travels 40 miles per hour for 3 hours, the distance traveled is 120 miles. Write a program that asks for the speed of a vehicle (in miles per hour) and the number of hours it has traveled. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph for a 3 hour time period, it should display a report similar to the one that follows:
Input validation: Do not accept a negative number for speed and do not accept any value less than 1 for time traveled (i.e. use a loop to keep on asking the user till he\she gives you an acceptable value for both).
Write a program that will predict the size of a population of organisms. The program should ask for the starting number of organisms, their average daily population increase (as a percentage), and the number of days they will multiply. For example, a population might begin with two organisms, have an average daily increase of 50 percent, and will be allowed to multiply for seven days. The program should use a loop to display the size of the population for each day. So for the previous example, the output should look like:
Input validation: Do not accept a number less than 2 for the staring size of the population. Do not accept a negative number for average percent daily population increase. Do not accept a number less than 1 for the number of days they will multiply.
Write a program with a loop that lets the user enter a series of integers. The user should enter -99 to signal the end of the series. After all the numbers have been entered, the program should display the largest and smallest numbers entered.
Write a program that displays a table of centigrade temperatures 0 through 20 and their Fahrenheit equivalents. The formula for converting a temperature from centigrade to Fahrenheit is:
F = 9\5 * C + 32
Where F is the Fahrenheit temperature and C is the centigrade temperature. Your program must use a loop to display the table.
Write a multiplication tutor program. Ask user to solve problems with random numbers from 1-20. The program stops after an incorrect answer. The output should look like:
14 * 8 = 112
5 * 12 = 60
8 * 3 = 24
19 * 14 = 256
Incorrect; the answer was 266
You solved 2 correctly
