CISC 192: Loops Lab

Lab topics:

• For loops
• Nested loops
• While loops
• Infinite loops

Its hip to be square. In this lab the user provides a size. The size dictates the number of ASCII characters and the characters themselves the program will print in a square. The diagonal of the square will print the size provided. The number printed decreases by 1 as its position moves away from the diagonal. The program repeatedly asks for a size and prints the square until the user terminates the program with CNTL-C.

Example output:

Enter the size of the square:

5

5 4 3 2 1

4 5 4 3 2

3 4 5 4 3

2 3 4 5 4

1 2 3 4 5

Enter the size of the square:

8

8 7 6 5 4 3 2 1

7 8 7 6 5 4 3 2

6 7 8 7 6 5 4 3

5 6 7 8 7 6 5 4

4 5 6 7 8 7 6 5

3 4 5 6 7 8 7 6

2 3 4 5 6 7 8 7

1 2 3 4 5 6 7 8

Enter the size of the square:

^C

Press ENTER to continue.

Some hints and gotchas to look out for.

• Make sure you have the correct diagonal
• My solution used 4 loop structures
• Use the attached output files to compare against your output. The two should be identical, including whitespaces, before you submit. NOTE these output files do not include user inputs.
• Notice the newline after the user input and after the square prints.
• Tabs separate the numbers in the square
• Remember to zip the entire project directory, including project file and source code
• Remember to use the zip format
• You can submit multiple times before the deadline

Rubric

• 5 points for matching output, output other than the square
• 5 points for using appropriate loop constructs (while vs. for)
• 2 points for handing infinite iterations of printing squares
• 3 points for printing a correct square size (the correct number of characters)
• 5 points for printing the correct numbers in the square
• 0 points for a project that doesnt compile
• -1 point per warning when compiling

strggling to figure out what combination of loops is required to make the desired output.
