025903_CH02 DaleLab 18 20 Exercise 3: Change the program so that only the outline of each square is shown. Here is an example row: ss$ss$$$ SS$$$S$$ SSS$SSS$ s$$SS$$S $$$SS$$ S$$SS$$ SSS$SS$ Compile and run your program. Exercise 4: Change the program from Exercise 3 so that the squares are 8 by 8 rather than 5 by 8. Here is an example row: $$$S$$ Compile and run your program. Clearly an 8-by-8 design is not a square but a 5-by-B design is. Explain
