Lab 3

1. Printing a character in a loop (charloop.cpp)

Write a program that asks the user for a symbol (using a variable of type char, rather than of type int or double) and a number of copies to print, and prints a line of that many copies of that symbol.

(If the user enters an integer less than 1 for the number of copies to print, a properly written loop will iterate zero times, and not print out any symbols. For this lab problem, this behavior is fine; there is no need for additional error checking.)

Here is one possible output format:

What symbol would you like to print? b

How many copies? 6

bbbbbb

Press any key to continue

2. Counting up and down (countUpDown.cpp)

Write a program that asks the user for an integer, and counts up from 1 to that integer and then back down, with all the numbers on the same line.

The output should look exactly like mine, given the same input. Here are two example runs:

Enter an integer: 6

1 2 3 4 5 6 5 4 3 2 1 

Press any key to continue

Enter an integer: 1

1 

Press any key to continue

Hints:

• You will need two loops.
• The cout within each loop will print out the number followed by a space. Only the cout after both loops will have an endl or "\n".
• Make sure the given integer is only printed out once. If the input is 1, the output should be just 1 (not "1 1" or "1 1 1"). If the input is 2, the output should be "1 2 1".
• If the user enters a nonpositive (i.e. negative or zero) integer, a properly written loop will iterate 0 times, and not print out any numbers. This behavior is fine here.
