I think one of the first movies that really introduced the idea of computers and the power of networking (that had an impact on a young me) was WarGames which came out in 1983!
The way that the text was outputted in this movie was actually an inspiration for me to use that exact type of character by character printing in one of my early programs. I used it for a password / security program so that our Computing teacher could not see what games we had on our floppy disks! (see YouTube Video on the right to see the text effect in action).
Next, we use a simple For Loop with a Variable (called string in this example) which will loop through each character in the string and print each character out (one at a time!)
And there we have it! A simple way to obtain our printing effect!
