If-statement problems

New to Mathematica. I can't figure out how to use the if-statement for pure
flow control.

Here's an example:

A = {5, 6, 7, 8}
For [n = 1, n <= 4, n++,
 if [n == 1, a = A[[n]]];
 if [n == 2, b = A[[n]]];
 if [n == 3, c = A[[n]]];
 if [n == 4, d = A[[n]]];

I want to assign to a b c and d the 4 values from A. Obviously, that's not
what happens. How do I accomplish what I need?

Many thanks in advance!!!
