The above is working fine except i'm not able to get the title.
Below is the text file that i'll get the data from.
if i remove the title(Dr) it's working fine but as long as i put in the Dr it'll be having problem.
Can someone guide me how can i grab both title and country from same line?

I ran your code it seems to run fine. I did have to add #include <string> and <ctime>


The output I got
Enter your info file name: input.txt

Begin reading of input.txt
File name input.txt closed for reading

Hi Yanson yes it's working fine.
but you can see inside myinfo struct I've include title.
So Dr in front of Country is for title.
I've declared titles inside enum.
Now I need to grab the title from text file and display it at the output.
But i'm not able to grab title and country from same line so i'm trying to figure out about it.
