Because division by O is not defined, the function should return 0 if N = 0. Note that the main program is written for you, and cannot be modified. Your job is to write the function avg defined in "util.cpp"; you select this file from the drop-down list above the editing window. You can test in "Develop mode" by clicking "Run my program", clicking anywhere in the terminal window, and then entering an array size. The main program will generate a series of random numbers and then call your function. When you are ready to submit, switch to "Submit mode" and click "Submit for Grading". You have unlimited submissions; the system records your highest score across all submissions. # Working with zylabs Some background on the zyLabs programming environment.
