A syntax mistake on one line may not be detectable to the compiler until a subsequent line. In general, when the compiler reports an error, start at the indicated by the error message and scan upwards.

By the way, consider your two loops. The outer loop has n going from 1 to 6. What is the range of a inside the inner loop when n is, let's say, 3?

By the way, the C Standard requires that main return an int. You defined it to return void.
