Algorithm To Print A Hollow Square Of Stars

ALGORITHM:

Step 1:

Start the program and get the value of n from the user

Step 2:

Initialize two nested loops for rows and columns

Step 3:

Initialize the variable i to 0 and loop through until i < n

Step 4:

Within the i-loop, initialize the variable j to 0 and loop through until j < n

Step 5:

Within the j-loop, add an if-else statement to check if i=0 or j=0 or j=n-1 or i=n-1

Step 6:

If the condition is true, print a “*” character

Step 7:

If the condition is false, print a blank space “ “

Step 8:

After printing each character, increment the value of j by 1

Step 9:

After the j-loop, add a command to create a new line

Step 10:

After the i-loop, end the program
