While the zyLab platform can be used without training, a bit of training may help some students avoid common issues. The assignment is to get an integer from input, and output that integer squared, ending with newline. (Note: This assignment is configured to have students programming directly in the zyBook. Instructors may instead require students to upload a file). Below is a program that's been nearly completed for you. Click "Run program". The output is wrong. Sometimes a program lacking input will produce wrong output (as in this case), or no output. Remember to always pre-enter needed input. Type 2 in the input box, then click "Run program", and note the output is 4. Type 3 in the input box instead, run, and note the output is 6.
