What's Wrong With Dumping?

I came to school very late, i arrived 11:15Am, knowing the fact that my class starts at 10:30AM. Since today is our Hands-On Exam, it doesnt really matter whether i came to school early or not. Luckily i was picked as the last one to perform the said practical exam....... so i did the reviewing and stuffs, then at the time i was on the "grill", i did everything that i knew. I knew that i did well during the programming then on, it just happened that a wrong output was displayed. Since the required output wasnt displayed, i tried to simulate the program, but then the entire program was correct, as i try to figure out what was wrong, i just found out that i was wrong with the Dump function of the MTS 88.C. I was really disappointed this day but i realized that it's part of being a student. Enjoy life and have fun!! =)
