scrolling text..

ok ive tried a couple things but to no avail.
my problem is, i wanna be able to input a string and make the program scroll it from left to right on the screen, in a defined length (for if i only wanna see 3 characters at a time or something)

any ideas/pseudocode will be appreciated :D

the only way I could think of right now is inputing whatever you want displayed in a cstring/array and then printing it in a for loop everytime putting a system pause after each letter....
