I tried running colorTest.cpp in visual studio. By the way, the output screen went too fast and it was hard to see at a glance. "rang" function and output screen did not match well. So we created a "twinkle_colors" function that makes certain text twinkle so that we can easily see the color change. I used the rand and srand functions. I also used the upLinePrompt function, which allows you to go to a specific location on the console screen and re-print the text.
