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()

Perfective maintenance: It basically improve the performance of the system, efficiency and maintainability. This type of maintenance are initiated by the IT department.
Adaptive maintenance: It involves the implementation changes in the system to increase its functionality. It basically improve its efficiency and increase its capability. It is less urgent than corrective maintenance.
