Hello friends, I am trying to show my students that a computer program is an arrangement of numbers. My kids love only video games and sports, but not every child is going to go on to play and make a living in sports. I am trying to get them interested in something other than sports. I am trying to engage then in something that they like that is more practical for them in the long run. I am not a computer programmer, but I know the importance of it. What you see here is what I have learn and read in books, but it is not working. I have tried many times to gain help in fixing this code, but no one in the forum wanted to help. They only wanted to make comments to show there arrogance. I have deleted some of it in order to make it short and simple. I can do some basic things, but now its getting very complicated. All i am attempting to do is read a file piece by piece, turn each byte into a number and SHOW IT, turn the number back to a byte and SHOW IT, then reassemble back the file and save it to another location the computer. That's all the kids want to see.
