How can I take only part of and array. If the array slot holds this:

words.doc

but I only want this:

words

How can I explode this or split it so I only get whats before the period. Thanks

char bomb[] = "words.doc";

/* Find the dot */
char* dot = strchr(bomb,'.');

/* Terminate string at dot */
*dot = '\0';

printf (bomb); /* you should get words */

Supposing str[] is the array in which you stored the word and substr[] is the array in which you are storing the substring.
i=0;
while(str[i]!='.')
{
substr[i]=str[i];
i=i+1;
}
substr[i]='\0';

Also you can use strtok() function if you want to split the string into multiple substrings if there are more than one '.'

So when I add values to an array the array is not reset. For example if I put this in an array:

char person[20];

strcmp(person, "chuck");

Then I put:

person[] = '\0';

Will the first index in the array (person[0]) will that be a 'c' or a '\0'.

Thanks

In your previous email you wrote
strcmp(person,"chuck") and I assume it to be strcpy(person,"chuck"). strcmp is to compare strings and strcpy is to copy string.
You cannot do person[]='\0'; as it is improper syntax. you have to give the index of the array when assigning a charecter.
'\0' is a character and person[] is not a character but person[0] or person[1] etc is a character.

A string is an array of characters.
