int num;

f = fopen ("TextFile1.txt" , "r");
if (f == NULL) perror ("Error opening file");
else
{
while ( ! feof (f) )
{
if ( fgets (buffer , 100 , f) == NULL ) break;
cout << "read " << buffer;

char *p = strtok(buffer, " ,"); // ',', space
while (p)
{
if ((*p >= 'A' && *p <= 'Z') ||
(*p >= 'a' && *p <= 'z'))
{ // A-Z, a-z
cout << p << endl; // do your job
}
else if (*p >= '0' && *p <= '9')
{
strstream ss(p, strlen(p));
ss >> num;
cout << num << endl;
}
p = strtok(0, " ,");
}
}
fclose (f);
