Jerry checks out the latest version of the repository and starts working on a project. He creates array.c file inside the trunk directory.

[jerry@CentOS ~]$ cd project_repo/trunk/

[jerry@CentOS trunk]$ cat array.c

The above command will produce the following result.

#include <stdio.h>
#define MAX 16

int main(void) {
   int i, n, arr[MAX];
   printf("Enter the total number of elements: ");
   scanf("%d", &n);

   printf("Enter the elements\n");

   for (i = 0; i < n; ++i) scanf("%d", &arr[i]);
   printf("Array has following elements\n");
   for (i = 0; i < n; ++i) printf("|%d| ", arr[i]);
   
   printf("\n");
   return 0;
}

He wants to test his code before commit.

[jerry@CentOS trunk]$ make array
cc     array.c   -o array

[jerry@CentOS trunk]$ ./array 
Enter the total number of elements: 5
Enter the elements
1
2
3
4
5
Array has following elements
|1| |2| |3| |4| |5|

He compiled and tested his code and everything is working as expected, now it is time to commit changes.

[jerry@CentOS trunk]$ svn status
?       array.c
?       array

Subversion is showing '?' in front of filenames because it doesn't know what to do with these files.

Before commit, Jerry needs to add this file to the pending change-list.

[jerry@CentOS trunk]$ svn add array.c 
A         array.c

Let us check it with the 'status' operation. Subversion shows A before array.c, it means, the file is successfully added to the pending change-list.

[jerry@CentOS trunk]$ svn status
?       array
A       array.c

To store array.c file to the repository, use the commit command with -m option followed by commit message. If you omit -m option Subversion will bring up the text editor where you can type a multi-line message.

[jerry@CentOS trunk]$ svn commit -m "Initial commit"
Adding         trunk/array.c
Transmitting file data .
Committed revision 2.

Now array.c file is successfully added to the repository, and the revision number is incremented by one.
