Programs: Due Sep 28, 2007
1. Your program will input two integers a, and b; two doubles x, and y; and two char
ch1, and ch2. Output each of the following calculations: (Example: if you were
outputting the answer to a., and you had a = 5 and b = 7 the output should look
like: 5 / 7 = 0). If the computer does not allow you to perform a certain
calculation, state the reason why as the output. For example, if a % x is not
allowed output a % x is not allowed because of __________.
a. a / b
b. b / a
c. a % b
d. b % a
e. a / x
f. x / a
g. x % a
h. a % x
i. cast x to an int
j. cast a*b to a double
k. cast a*b to a char
l. ch1 + ch2
m. ch1 / ch2
n. ch1 + a
o. cast ch1 + a to a char.
2. Write a program that computes the area of a triangle. You input the length of one
side called the base, the length of a second side called a, and the included angle
(in degrees). The program computes the area of the triangle.
Degree Radian

a. Your program will need to change the angle to radians
180

b. You will need to calculate the height: h  a sin(  )
1
c. Compute the area of the triangle: A  * base * height
2
d. Output the results.
3. Create an applet that draws a funny face. It should have eyes, eye brows, nose,
mouth, ears, a few freckles, and some hair.
