Question

This assignment will give you practice on basic C programming. You will implement a few C
programs

Task 3: Entab/Detab Utility
The tab character ('\t') is both useful and annoying. You will write a program, called tabutil.c, with
the following features:
• tabutil -d <num_spaces> will read from stdin and print to stdout, replacing every tab occur-
rence with num_spaces consecutive spaces. For example, tabutil -d 4 will turn each tab into
4 spaces.
Homework 2
2
System Skill
• tabutil -e <num_spaces> will read from stdin and print to stdout, turn each occurrence of
num_spaces consecutive spaces into a tab (i.e., does the reverse of -d).
Code and Compilation: Your code will be one standalone file called tabutil.c. Use the following
command to generate an executable vert_hist. Your code must compile clean with this command.
gcc -Wall -W -pedantic -o tabutil tabutil.c
