Discussion Overview

The discussion revolves around modifying a coding simulation of a "bugs life" program originally written for Turbo C++ to run in modern compilers like Code::Blocks or Dev-C++. Participants are exploring issues related to code readability, formatting, and compatibility with different compilers.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses difficulty in reading the original code due to poor formatting and suggests compiling it with the desired compiler to address errors.
  • Another participant comments on the formatting issues, indicating that it appears to be an auto-indent problem and offers to assist with the code.
  • A third participant provides a modified version of the code that is compatible with Dev-C++, along with improved indentation.

Areas of Agreement / Disagreement

There is no consensus on the best approach to modify the code, as participants have differing opinions on formatting and readability. The discussion remains unresolved regarding the specific modifications needed for compatibility.

Contextual Notes

Participants have noted limitations in the original code's readability and structure, which may affect the ease of making modifications. Specific compiler errors have not been detailed, and assumptions about the original code's functionality remain unaddressed.

my friend had send to me a coding simulation of bugs life
but this program only can running in TC++ 3.0 or higher

how to modified it able to run in Codeblocks or Devc++...anyone can help me

program:
Code: 
#include<iostream.h>
#include<conio.h>
#include<stdio.h>
#include<string.h>

Yuck. This code is very difficult to read, and I consider myself a messy coder...

What you want to do is try and compile it with the desired compiler and sift through the errors it spits out one by one, then eliminate them. If you get stuck you can always post those up here for help, although you will get a faster result if you google the error line. The output on error for most compiler errors in most compilers will usually google to the answer you want.

If you were consistent with the spaces, tabs and returns it would look a lot tidier and be easier to read, as it stands I keep getting confused about the scope because of the bad {} placement.. comments would help too.
 
Yikes! What's with the formatting? It looks like an auto-indent gone awry.

I'll see what I can do.
 
I'm almost tempted to give this a code critique...

Here's the Dev-C++ compatible code, with fixed indenting.

Code: 
#include <iostream>
#include <time.h>
using namespace std;

Jheriko...tq 4 suggestion

Sans...tq 4 ur time


Code: 
display();
        cout << "do u want to go to next time step press y for yes";
        cin >> ch;
why the output not continue to this part?
 
It does, it just doesn't display the same cout the first time it prompts you to continue.

If you wish to do that, you must enter the line...
Code: 
cout << "do u want to go to next time step press y for yes";
Before the initial prompt, like so (see bolded line at bottom):

Code: 
#include <iostream>
#include <time.h>
using namespace std;

int a[20][20], p=0, q=0;
void step(int g, int h, int i, int &u, int &v);
