CSE $121--$ Introduction to $"$C$"$

Extra Credit #$1($Worth $5$ pts$)$

Due on last day of class at $11$:$59$PM

Name your program: extra$1.$c

This assignment will introduce how to incorporate command$\_$line arguments into your program. Until now, if we wanted our program to get data from a user, we had to ask the user for specific input and then capture that input with scanf$().$ In many cases, we would like the user to enter data at the same time they run the program. For example, when we use the $""$ command to submit our programs, we enter the program name $($i$.$e$.cp)$ along with the file to copy and where to copy it$.$ For example:

cp p$5.$c $/$home$/$faculty$/$skoss$/$cse$121/$your$\_$UID

So this assignment is about writing a little utility program called submit, which will make it easier for you to submit your weekly programs. After you create this utility, you can simply type $./$submit$,$ followed by your px$.$c$,$ and it will be copied to your directory in my account.

For example, to submit p$5.$c you would type:

$./$submit p$5.$c

Below is the code for this utility. When you compile it$,$ use the following command: gcc extra$1.$c $-$o submitTo learn more about the functions "sprintf$()"$ or "system$()",$ you can google or man$\_$page them. sprintf$()$ is declared in
