Programming Assignment #1

 

 

 

 

1.Swapping *:

 

The following pseudocode describes a simple algorithm which swaps the values in two variables, x and y:

 

1  print “Enter initial value of x: ”

2  input x

3  print “Enter initial value of y: ”

4  input y

5  set temp to x

6  set x to y

7  set y to temp

8  print x = x, y = y

 

a)    Trace the above pseudocode for x input of 8 and y input of 3, using the following header:

 

Use a separate row for each line of pseudocode.

 

 

b)    Write a Java Program that implements this algorithm.

 

 

 

 

 

2.     Circle Parameters *:

 

Write a Java program that generates and prints circle-related values. Read in a value for radius. Calculate and print the corresponding values for diameter, circumference, and area. Use the built-in Java constant Math.PI for the value of π. Use Math.PI the same way that you would use 3.1452 in your program – there’s no need to declare Math.PI with a declaration statement, just use it.

 

Sample session:

 

Enter a radius value: 2.5

Diameter = 5.0

Circumference = 15.707963267948966

Area = 19.634954084936208
