Simple and easy Update my mini program as a Unix Shell

Project Objective: Complete a C program so that it is a simple Unix shell. The basic C program file will be provided. Tasks: (1) Complete the for loop so that it correctly constructs the args array (without using any functions) (2) Add an if-else to check for the commands "quit" and "cd”. - In the case of "quit" the program ends. - In the case of "cd" the program will call the chdir() system call to change the current directory. The parameter to chdir() is the directory to change to, which will be the command-line argument provided by the user. (3) If the command entered by the user is something else, the program assumes the user wants to run another program and uses the system calls fork(), wait(), and execvp() to run that program. The code to do this is already present in the program. Must comment every action since this program will be used as a learning tool. 24 hours turn around. $30
