reading strings from file to struct array in C

I am trying to read strings from file and add them to my array of structs but when i do i get some random characters at the end of one or two strings.Here is my code for reading strings line by line:

while ((read = getline(&line, &len, fp)) != -1) {
strncpy(&structures[i].id,line,4);   //copies the first four characters to my array of structures
...
}

When i print out the structures[0].id it prints "WW23�" when it should be just "WW23".It does that with couple of strings, although not with all of them. My struct looks like this.

struct observers
{
 char id[13];
 ...
};

It reads from file properly at least it gets the integer values right.

You probably need to add '\0' as the 5'th character to terminate the string.

You are not terminating the string. Add '\0' at the end structures[i].id[4] = '\0'. It should work fine.
