作为Java程序从C ++导出到Eclipse

Question

So I have a program that I wrote in C++ (it's a generator) and when you type in some options, it generates a java code in the console, but it can't be copy/pasted and is hard to read (that's just the way windows console is). Is there a way to make that generated java code export into eclipse so that the person can edit it? Even better, could that code be exported to a .jar file?

Answer 1

You could always redirect the console output to a text file using > pipe:

C:\> myapp.exe > output.java

Alternatively, here is a tutorial on how to write to file in C++ http://www.cplusplus.com/doc/tutorial/files/

Update: A short example on how to output the .java file.

#include <iostream>
#include <fstream>
using namespace std;

int main () {
  ofstream myfile;
  myfile.open ("Hello.java");
  myfile 
  << "public class Hello {" << endl
  << "  public static void main(String[] args) {" << endl
  << "    System.out.println(\"Hello World\");" << endl
  << "  }" << endl
  << "}";
  myfile.close();
  return 0;
}

Answer 2

How about saving the generated code into a *.java file instead of printing it to the cosnole??? to generate a jar file you can either do it on the console using the command "jar" or use eclipse or something to generate the jar

You have to read a bit about c++. Here's how to handle file io http://www.functionx.com/cpp/articles/filestreaming.htm
