converting

[sharktlp]

I have a file that contains employee info such as name telephone address id salary. I used in.getline to store them in respective fields (employee.name, employee.id) the problem is i used char for ID so i can use in.getline but i need to convert it to int so i can sort by id. how can i convert employee.id to int?

What's a problem? Use Standard atoi() from <cstdlib>:

char* chr;
int   i;
...
i = atoi(chr);
// or if std:string text:
string s;
...
i = atoi(s.c_str());

Warning: atoi() returns 0 if its arg is NaN (i.e. atoi(&quot;Junk&quot == 0...
