The program is an illustration of loops and conditional statements
<h3>
Loops</h3>
Loops are used to perform repetitive operations.
<h3>
Conditional statement</h3>
Conditional statements are used to make decisions
<h3>The python program</h3>
The program in Python, where comments are used to explain each line is as follows.
#The following is repeated 5 times; i.e. the rows
for i in range(5):
#The following is repeated 5 times; i.e. the columns
for j in range(5):
#For rows 2 and 5
if i == 1 or i== 3:
#For columns 1 and 5
if j == 0 or j == 4:
#This prints *
print('*',end='')
#For other columns
else:
#This prints an empty space
print('',end=' ')
#For other rows
else:
#This prints *
print('*',end='')
#This prints a new line
print()

Answer:
true
Explanation:
a while loop is a condition-controlled loop. While loops continue no matter what under a certain condition, unless you insert the keyword <em>break.</em>
One example in python is this:
while x > y:
<em>pass</em>
The keyword to break a while loop may vary depending on the coding language you are using.
<u>Tip</u> The pass keyword allows a no error contact between loop and the terminal. Pass in a nutshell is almost as if saying nothing at all, but just leaving the condition blank. We only use pass because it prevents errors instead of no value.

Answer:
a. Object cannot be converted to Person
Explanation:
This program demonstrates polymorphism.
e.g., a Student IS a Person therefore you can call m() with a Student as well as a Person object.
The same goes for GraduateStudent.
However, and Object is not a Person, so the last call fails. This can be deducted by the type checking that happens at compile time.
