The input will come from stdin. Your program should downcase all input letters and ignore symbols besides a to z. The output is a histogram rendered vertically. Please make sure you must support reading multiple lines if you pipe the input from a file using the cat command. Code and Compilation: Your code will be one standalone file called vert_hist. c. Use the following command to generate an executable vert_hist. Your code must compile clean with this command. gcc -Wall -W -pedantic -o vert_hist vert_hist.c Example: Below is an example assuming vert_hist has been compiled and lives in the current directory. Each * represents a count of 1. echo This Is a TeST--Hello, MississippI. Yippie | ./vert_hist * * * % abcdefghijklmnopqrstuvwxyz Hint: Learn about the function getchar.
