How does I check for periods?

[Unregistered]

I am writing a program using linked lists. A data file with multiple sentences are stringed together in one line. For example:

I have a dog. I have a cat. I hate dogs and cats.

I need to identify each sentence... and I believe the way to do this is to check for periods. What kind of function do I need to write to check for periods?

Sentences not always end with '.', but since you have presumed sentences to end with '.',

main()
{
        char t_str[255], *str = "I have a dog. I have a cat. I hate dogs and cats.";
        int i;

        while(*str) {
                i = 0;
                while(*str && *str != '.') {
                        t_str[i ++] = *str ++;
                }
                t_str[i] = '\0';
                puts(t_str);

                *str ++;
        }
}
