I'm new.I am making a hospital management system and i am stuck at a point where i have to search all the patients with specific doctor. I have developed a code but it does print everything present in the file. i only want to search with doctor name and every patient with that doctor should come up. here is my coding(the bold function is actually my problem):
#include<iostream>
#include <fstream>
#include<ctime>
