/*Slight modification to ex1_13.c that makes charCount an array of ints 11 entries long, in order to circumvent the need for additional mathematical operations down the line as a consequence of ocurrences of the value "1" being store at position 0. This sacrifices 4 bytes of memory in the stack by extending the array, but results a shorter binary.
