Consider the attachment.

Explanation:

• The "*" and  "$" are stored in  a variable under first for loop since we want the number to always start printing from "*" followed by "$".
• The 2nd for loop print these by swapping values. c stores value of a , b stores value of a and a stores the final value of c. Thus successfully swapping the values.
• Print something ; : prints stuff in the same line.
•  Print : Returns new line.
