how would i create an algorithm that generates a farely convincing terrain landscape that is not all choppy with 1 pass currently all i do is rand()%5+1 and break that up into a switch and then do more randoms for certain cases but its still looks pretty choppy. im just wondering if this can be done without multiple passes

Use 2d-perlin noise as a basis for your heightmap. Check out this link for an explanation of perlin noise.

Practically everone into graphics at college do this as a project one time or another, so plenty of info is out there, just search for it.
