Exercise 3
Write a program to copy its input to its output, replacing each tab by \t, each backspace by \b, and each backslash by \\. This makes tabs, backspaces and backslashes visible in an unambiguous way.

Exercise 4
Write a program to print a horizontal histogram of the frequencies of different characters in its input. To keep the problem a little bit simple, you can ignore the differences between uppercase and lowercase letter, and you can also ignore non-alphabetic characters in the input. Your output should be something like:
4 x x x x x x x 3 xx x xx x x x xx xxx 2 xx xxxxxx x x xxx xxxxxx 1 xxxxxxxxxxx xxxxx xxxxxx abcdefghijklmnopqrstuvwxyz
Use a 26-element array to store the counts of the observed characters, rather than 26 variables!
