Question
Transcribed Text
(1) Star patterns
Star patterns are patterns using asterisks -*", to create specific shape, e.g., square,
triangle(pyramid), rhombus etc. Write a C code that takes a character C as shape value
and an integer n as the size of the shape and output that specific shape using asterisk ******
of size n. Following is the list of shapes and associated character inputs you need to
implement. Write separate function to print each shape.
Shape Name
Associated Character
Example patterns for n = 5
Hollow Square
S
Hollow
r
Rhombus
Hollow
p
Pyramid
Diamond
d
Cross
c
(2) Variable Pricing
Variables, a new bar, has a very unusual pricing policy for the two drinks that it sells
(called A and B here for simplicity). At the start of each night, each drink costs $5. Each
time a drink is purchased, its price goes up $1 for the next patron (the prices change
independently; if someone purchases drink A, its price goes up but the price for B stays
the same). In order to prevent prices from getting too high, a drink's price cannot exceed
$11; after a drink is sold for $11, its price resets back to $5 and begins to rise again.
For example, suppose several drinks are purchased in the following order: A, A, A, B, B,
A, B. The corresponding prices for these drinks (in order) would be $5, $6, $7, $5, $6,
$8, $7.
Write a C program, which reads in a sequence of drink orders from the user (as a series of
capital As and Bs, with no spaces or other characters). Your program should print out the
total cost of all the drinks sold (in the example above, the total cost would be $44).
Sample Input:
AAABBAB
Sample Output:
44
Hint: Your program must be able to accept a sequence of drink orders of any length, so a
while loop with getchar () would probably be the best strategy here.
(3) Perfect number
A perfect number is a positive integer that is equal to the sum of its proper divisors. The
smallest perfect number is 6, which is the sum of 1+2+3. Write a function
is Per fect to check if a number is a perfect number. If the number is perfect the
function returns true otherwise false. Write a test code which takes a number n as
input and Output whether it is a perfect number or not.
(i) Sample Input: 6, Sample Output: 6 is a perfect number
(ii) Sample Input: 10, Sample Output: 10 is not a perfect
number

printf("\nPick from the following shapes: ");
scanf("%c", &sha);
// Prompt the user to enter the length or number
printf("\nEnter the length: ");
scanf("%d", &x);
// Checks for the letter and prints out the shape accordingly
switch (sha) {
case 's':
{
// Calls Hollow Square Function
hollowSqr(x);
break;
}
case 'r':
{
// Calls Hollow Rhombus Function
hollowRho(x);
break;
}

{
// Calls Hollow Pyramid Function
