Error in structure, trying to cin info from text file.

#include <iostream>

#include <fstream>

using namespace std;
void getstudents();

struct stinfo
{
     char student_name[20];

         }                                         
                                //"expected primary-expression before '[' token

There is no stinfo[] object. stinfo for all practical purposes is a type.

Aw man do you think you can explain how I can stick the info from my text file into those variables in the structure? I have been trying all day and cannot figure it out!

[Albatross]

Replace the stinfo in that line with students, which you declared earlier.

Oh, and do consider using strings in place of char[]s.

[whitesnow]

stinfo students[6];
         for (int i=0; i < 6; i++)
         {
             getline(fin, students[i].student_name);
         }

Ok I changed that part to this but I am receiving another error now.
I am using dev c++ if it matters.

It says, no matching function for call to `getline(std::ifstream&, char[20])'

[firedraco]

That is because getline() takes an std::string as the second parameter, not a char array.

[whitesnow]

Ok I tried

typedef basic_string<char> student_name;

and then I get, invalid use of `stinfo::student_name'

Dang I have never used this sort of string command before I am not sure if I am doing it wrong.

This assignment is so we learn to use structures so I have never done it before and it's confusing me since I have to read from a .txt file. I cannot get it to work that's all I want to do is stick these inputs into those structure variables.

There's exactly enough grades to fit.

Aw, come on... string is a defined type if you #include <string>...

Nice!!!!! I got no error!!!!!

Now how can I cout student_name to display the persons name?

cout student_name is undeclared.

Thanks for all the help I will check out the link also.
