    Try this:

    FILE *fin;
    check_email(char *email)
    {
    int i, is_email=0;
    for (i=0; i<strlen(email); i++) //*****Change this

    include <string.h> to use strlen().

    or equivalently use strchr.

    char* strchr(const char* cs, int c);
    Returns pointer to first occurrence of c in cs, or NULL if not found.
