Exercise #2 Frequency Analysis: One of the oldest approaches to breaking a code is to perform a frequency count of letters. Write a C++ program to perform a frequency count by reading the text from a file (code.txt). Your program should output how many A's are there in the text, how many B's are there, and so on.
