little help

[mars4bb]

Can I have a "little" help in the right way....

Write a program to generate personalized junk mail. The program takes input both from an input file and from the keyboard. The input file contains the text of a letter, except that the name of the recipient is indicated by the three characters #N#. The program asks the user for a name and then writes the letter to a second file but with the three letters #N# replaced by the name. The three-letter string #N# will occur exactly once in the letter.

Hint: Have your program read from the input file until it encounters the three characters #N#, and have it copy what it reads to the output file as it goes. When it encounters the three letter #N#, it then sends output to the screen asking for the name from the keyboard.


this is what I got...

#include <iostream>
#include <fstream>
#include <cstdlib>


int main()
{
	using namespace std;
	
	char infile[50], name[50];


	ifstream instream;
	ofstream outstream;


cout << "Hello!\n";

cout << "Please enter your name: ";
cin >> name;

	instream.open("infile.txt");
	if (instream.fail())
	{
		cout << "Input file opening failed.\n";
		exit(1);
	}

	outstream.open("outfile.txt");
	if (outstream.fail())
	{
		cout << "Output file opening failed.\n";
		exit(1);
	}

	instream >> "Enter your text: ";
	outstream << "Your out stream is" << infile;

	instream.close();
	outstream.close();


	return 0;
}

instream >> "Enter your text: ";

That doesn't do anything. You need to read into a variable - probably a string or character. Try just reading in the letter and outputting it to cout first and see if you can get that working.

Search the text until you find #. Check if Text[CurrentPosition+1] is N and Text[CurrentPosition+2] is #. If not, skip this # and search for the next.
