1) if you can use cin.getline(), for parameters see in doc
2) to convert you can use atoi-i for int (const char *) or atol - l for
long,
    see man atoi, also you have to include stdlib (man tells you the needed
header also)
3) include <time.h> and use gmtime, it returns a pointer to a struct with
all information
    you will not need to convert the year at all, it is in this struct .(as
member)
4) I don't know what is wrong, but try it in this way
    int c;
    while((c=fgetc(pF))!=EOF){// it reads first from file, c is an int !!}
Ok , good luck
