Infile incomplete type error
24,974
File streams are defined in the header <fstream>
and you are not including it.
You should add:
#include <fstream>

I am building a program that takes an input file in this format:
title author title author etc and outputs to screen title (author) title (author) etc
The Problem I am currently getting is a error:
"ifstream infile has incomplete type and cannot be defined"
Following is the program:
#include <iostream> #include <string> #include <ifstream> using namespace std; string bookTitle [14]; string bookAuthor [14]; int loadData (string pathname); void showall (int counter); int main () { int counter; string pathname; cout<<"Input the name of the file to be accessed: "; cin>>pathname; loadData (pathname); showall (counter); } int loadData (string pathname) // Loads data from infile into arrays { ifstream infile; int counter = 0; infile.open(pathname); //Opens file from user input in main if( infile.fail() ) { cout << "File failed to open"; return 0; } while (!infile.eof()) { infile >> bookTitle [14]; //takes input and puts into parallel arrays infile >> bookAuthor [14]; counter++; } infile.close; } void showall (int counter) // shows input in title(author) format { cout<<bookTitle<<"("<<bookAuthor<<")"; }
