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. Note that the program will not make any distinction between uppercase and lowercase letters. It will output the results to the screen and in a text file (count.txt) Sample output (for code.txt): A: 3 B: 3 C: 23 D: 13 E: 41 F: 4 G: 9 H: 15 1:44 J: 1 K: 0 L: 7 M: 9 N: 33 O: 16 P: 4 Q:0 R: 22 S: 24 T: 27 U: 8 V: 5 W: 1 X: 0 Y: 4 Z: 0
