Task $1$

Task $1$ is to copy and paste the code below into the project. This code asks the user for a height and then prints out a sideways pyramid. For example, the goal is to produce this output with a height of $4($although the actual code will be slightly wrong$--$we'll fix that in Task $2).$Task $2$

The Task $2$ tests, however, do expect whitespace to match exactly. To do that, look at the cout lines in both while loops. They both use setw, which sets the expected width $($so if setw$(5)$ is called, and then $"!"$ is output, it will output $4$ spaces so that the total width is $5$: four spaces plus the exclamation point$).$ We want to remove the $-1$ from both setw calls so that it prints the extra space that is expected. Make sure you remove it from both setw calls.

Now, submit the code. It should now pass Task $1$ and Task $2$ tests.

Task $3-$ Extra Credit

If you'd like to earn extra credit, use what you've learned from the code above $($especially the while loops and output$)$ to create a square of the given height. You should do this at the end of the main method $($keeping the existing code$)$ so that your program continues to pass the Task $1$ and $2$ test cases.You can assume there will always be distinct sides to the square $($so not a height of $1$ or $2).$

There are a few ways to make several # in a row, but one easy one is to use setfill, which changes what gets added to add width. For example:

cout $<<$ setfill$(\text{'}-\text{'})<<$ setw$(4)<<"$#$"$;

would output: $---$#

Instead of spaces to make the output $4$ characters long, there are dashes $($three $-$ and then the # for four total characters$).$

Note that we use single quotes around the dash, to indicate a single character rather than a string. Also, it's important to know that setfill persists, meaning the next time I do an output:

cout $<<$ setw$(4)<<"$#$"$;

it will still use the dashes as the fill. If I want to use spaces, I need to switch it back:

cout $<<$ setfill$(\text{'}\text{'})<<$ setw$(4)<<"$#$"$;

setw on the other hand does not persist. If I next do:

cout $<<"$#$"$;

That will just produce one # with no additional text before it$.//$ Copy$/$paste $($or type$)$ your code here
