Problem Statement 2:

Write a C++ program that prompts the user in seconds. The program then

outputs the elapsed time in hours, minutes, and seconds. (For example, if the

elapsed time is 9630 seconds, then the output is 2:40:30).

Problem Statement 3:-

Write a program that prompts the user to input a length expressed in

centimeters. The program should then convert the length to inches (to the

nearest inch) and output the length expressed in yards, feet, and inches, in that

order. For example, suppose the input for centimeters is 312. To the nearest inch,

312 centimeters is equal to 123 inches. 123 inches would thus be output as: 3

yard(s), 1 feet (foot), and 3 inch (es) .

Problem Statement 4:-

A milk carton can hold 4.78 litres of milk. Each morning, a dairy farm ships cartons

of milk to a local grocery store. The cost of producing one litre of milk is $0.41,

and the profit of each carton of milk is $0.51. Write a program that does the

following:

a) Prompts the user to enter the total amount of milk produced in the morning.

b) Outputs the number of milk cartons needed to hold milk. (Round your answer

to the nearest integer.)

c) Outputs the cost of producing milk.

d) Outputs the profit for producing milk.

PRACTICAL 9

Problem Statement 1:

Newton’s law states that the force, F, between two bodies of masses M1and M2is given by:

in which k is the gravitational constant and d is the distance between the bodies.

The value of k is approximately.

Write a program that prompts the user to input the masses of the bodies and thedistance between the bodies. The program then outputs the force between the

bodies.
