2. ..........
3...................;

ZZZZ:
1. ..........
2. ..........
3. ................;

1) open the file
2) read it in string.
3) use strstr to locate the YYYYY string
4) copy the string from : to ; to another string and return;

the returned pointer from strstr points to the beginning of substring you searched. Now skip the words you searched. copy character by character until you get ';'.

char *ptr;
char *tosearch = {"YYYY:"};

ptr = strstr(whole, tosearch);

ptr += strlen(tosearch);

copy ptr[i] to other variable until you get ;
