#include <iostream.h> // cin/cout
#include <fstream.h> // ifstream
#include <assert.h> // assert()
const int MAXCHARS = 80; // length of lines in file
void main(void)
{
char myString[MAXCHARS + 1];
ifstream inFile;
ofstream outFile;
// open input file
inFile.open("datafile.in", ios::in);
assert( !inFile.fail() );
// open output file
outFile.open("datafile.out", ios::out);
assert( !outFile.fail() );
// prime while loop (read one line from file)
inFile.getline(myString, MAXCHARS);
// while there is more data in the input file
while ( !inFile.eof() )
{
// write the line to the output file
outFile << myString << endl;
// get next line from input file
inFile.getline(myString, MAXCHARS);
}
inFile.close(); // close input file
outFile.close(); // close output file
}
Note: This input technique is also called buffered input
