I am trying to find a convergent sequence of continuous real-valued functions on $[0,1]$ whose limit function fails to be continuous at an infinite number of points. I have thought about $f_n(x)=x^n$ which is convergent to $1$, but how do I show the limit fails to be continuous at an infinite number of points?
