Print for loop iterations with their specific label

How can I get a for loop to print the specific iteration number it is on? For example I'm using a for loop to print the Fourier series coefficient, which I can do no problem, but rather than each print out be "an=", "an=", "an=", etc, how can I make it that each label is printing and incrementing, such as "a1=", "a2=", "a3=", etc. I apologize if the language of this request is confusing but hopefully the example I used is clear enough.

If you want to display that information then use fprintf or sprintf.

If you want to magically change variable names inside a loop then read this:

Don't think of naming variables dynamically but if it's for your label then sprintf()(lookup in the documentation) should do it.
