Q1. Write a program that stores monthly rainfall amounts in an array. The program then

displays the monthly rainfall amounts, the total annual rainfall amount, the average rainfall

amount, the highest rainfall amount, or the lowest rainfall amount First get the rainfall

amounts for the 12 months. Example:

Enter rainfall for month 1: 12.5

Enter rainfall for month 2: 15

Next, display the following menu and wait for the user response. Repeat the menu display

and the calculation as long as the user is not typing 6. (The rainfall amounts should be

entered only once in the program before displaying the menu.)

1 Display monthly amounts

2 Display total amount

3 Display average amount

4 Display highest amount

5 Display lowest amount

6 End program

Enter your choice: 1

displayMonthly: displays the monthly rainfall amounts

displayTotal: displays the total rainfall amounts for the entire year

displayAverage: displays the average rainfall amounts during the year.

displayHigh: displays the month with the highest rainfall amount

displayLow: displays the month with the lowest rainfall amount.

Q2. Write a C++ program that will display if a students is pass or not in his exam.

might use more than seven letters. For example,

225-5466 can be displayed as CALL HOME, which uses eight letters. Write a program that

prompts the user to enter a telephone number expressed in letters and outputs the

corresponding telephone number in digits. If the user enters more than seven letters, then

process only the first seven letters. Also output the A¸S (hyphen) after the third digit. Allow

the user to use both uppercase and lowercase letters as well as spaces between words.

area. Use the following formula: area = PI * r * r.

Use 3.14159 for Pi and the radius of the circle for r. If the user enters 2, the program

should ask for the length and width of the rectangle and then display the rectangle’s

area. Use the following formula: area = length * width

If the user enters 3, the program should ask for the length of the triangle’s base and its

height, and then display its area. Use the following formula:area = base * height * 0.5 If

the user enters 4, the program should end.

Input validation: Display an error message if the user enters a number outside the range of 1

– 4 when selecting an item from the menu. Do not accept negative values for the circle’s

radius, the rectangle’s length or width, or the triangle’s base or height.

Q24. Write a program that asks for the names of three runners and the time it took each of

them to finish the race. The program should display who came in first,second, and third

place.

Input validation: only accept positive numbers for the times.

Q25. Write a program that asks for the number of calories and fat grams in a

food. The program should display the percentage of calories that come from fat. If the

of calories. If that happens, display an error message indicating that either the calories or fat

grams were incorrectly entered.
