The owner of a strawberry farm has made the following arrangement with a group of students:
the may pick all the strawberries they want. When they are through picking, the strawberries will
be weighed. The farm will retain 50 percent of the strawberries and the students will divide the
remainder evenly among them. Assume that a strawberry weighs approximately 5g.
Write a complete program (12 marks) and draw the flowcharts (8 marks) for the above problem.
The requirements:
1) Use a function name GetStrawberry ( ) for the input (the weight of the strawberry in kg).
2) Use a function name GetStudent () for the input (the number of the students).
3) Use function name Calculate ( ) to calculate how many strawberries the farmer and each
students get.
4) Use function Display to display the answer.
(Hint: Function GetStrawberry(), GetStudent(), and Calculate() will be called from main while
function Display() will be called from Calculate()).
Sample output:
Enter the weight for the strawberry in (kg): 1
Enter number of students: 5
The farmer get 50 strawberries.
Each student get 10 strawberries.

A second-degree polynomial in x is given by the expression
known numbers and a is not equal to 0. The formula to find the roots:
, where a, b, and c are
Then, assume the result b2 – 4ac is always positive value.
Write a complete program (12 marks) and draw the flowcharts (8 marks) for the above problem.
The requirements:
1) Use 3 different functions for the input a, b and c such as GetA( ),GetB( ),GetC( ).
2) Use function name Calculate ( ) to solve the polynomial.
3) Use function Display ( ) to display the roots for the polynomial.
(Hint: Function GetA(), GetB(), GetC() and Calculate() will be called from main while function
Display() will be called from Calculate()).
Sample output:
Enter a: 1
Enter b: 6
Enter c: 2
The first root is -0.35
The second root is -5.65
