vivina is on a distinguished road

need help with some c++ coding..

i'm suppose to write out a program to convert a text file to a format whereby "Fly" program can read and draw the picture..
But it cant seem to be able to read properly from my text file or what coz when it draws the picture out it get abit distorted..

Here's my program:
CPP / C++ / C Code:
#include <string>
#include <iostream>
#include <fstream>
#include <stdio.h>
#include <strstream>
#include "FileConverter.h"
using namespace std;

	inputFilePath=in;
	string temp=inputFilePath;
	outputfilename="output_of_"+temp;
	paraOutfilename="paras_of_"+temp;
}
FileConverter::FileConverter(char *in,char *out){
	inputFilePath=in;
	outputfilename=out;
}
//use user reentered input file name to generate
void FileConverter::generateGraphParaFile(char *input_file_name){
	inputFilePath=input_file_name;
	generateGraphParaFile();

}
//use user default input file name to generate
void FileConverter::generateGraphParaFile(){
	string word,parameterStr,para2,para3,para4,para5, header, end;
	const string para1="frect",para6="10",para7="255",para8="10";
	int beginNum,endNum,noOfWordsReaded=0,sequenceNo=0,geneTwoSeqNO;
	const int geneOneLocation=2,geneTwoLocation=5,seqStartLocation=9,NOofWordsInALine=9;

	ifstream in(inputFilePath);
	//ofstream out("123.txt");
	ofstream out(paraOutfilename.c_str());

	//header = "new"; //+"size 1000,500"+"fill 1,1,255,255,255";
	out<<"new"<<"\n";

Have you tried running it through the debugger? You really need to be more specific as to what your problem is, and instead of supplying your entire source code, give us the code that pertains to the problem and let us know what kind of errors (assuming these are logic errors, not compiler errors) you are running into. If I were you, I'd be looking at the data as it is read from the file and before it undergoes the conversion that you are performing. Do a step by step and watch it perform each task at least once so that you can understand what is happening to the data as it is processed.

On a side note, I noticed that you are not testing most of your file I/O to see if it succeeded. While Stream I/O does protect you a bit more than low level and standard I/O, you still absolutely need to check to see if a file operation succeeded before you process any data. As I have said in a previous file I/O thread, a program that fails to test ALL file I/O operations is doomed to fail.

Need Help Again!!

how do i pass the data from this beginNum & endNum to
CPP / C++ / C Code:
				in>>word; noOfWordsReaded+=1;
				beginNum=atoi(word.c_str());
				para3=toString(80+(int)(beginNum/240000));

			//read next word after beginNum
				in>>word; noOfWordsReaded+=1;
				endNum=atoi(word.c_str());
				para5=toString(80+(int)(endNum/240000));

this function's beginNum & endNum??
CPP / C++ / C Code:

void FileConverter::calculatePercent(int *endNum, int *beginNum)
	{
	int calculate;
	calculate=((endNum-beginNum)/100);
	cout<<calculate;

	}

You must pass the address of the variables.

The function call would look like...

CPP / C++ / C Code:
calculatepercent(&endNum, &beginNum);

hmm got abit of prob doing that.... but nvm i put tat calculation part into the same function....
But now i got 1 prob.. when i use the calculate = endNum-beginNum
den when it check and loop but its not wat i wanted.... so how can i make sure that the para3=.......beginNum & endNum is the 1 i wanted from calculate=endNum - beginNum??

CPP / C++ / C Code:
calculate=endNum-beginNum;
if (calculate>=500)

{
para3=toString(80+(int)(beginNum/240000));
para5=toString(80+(int)(endNum/240000));
parameterStr=para1+","+para2+","+para3+","+para4+","+para5+","+para6+","+para7+","+para8;
out<<parameterStr<<"\n";
}

Sorry, I'm not sure what you're trying to do with the function, nor am I seeing any kind of a loop. You did mention a loop, didn't you?

well u see i need to calculate the difference between the endNum and the beginNum then i need to see if it's more then 50% if it is i will then draw a line..If it's lesser den 50% i dun draw...
overall i need to filter the result then draw a line...
below is basically what i use to draw rectangle and line..
CPP / C++ / C Code:
//use user default input file name to generate
void FileConverter::generateGraphParaFile(){
	string word,parameterStr,para2,para3,para4,para5, header, end;
	const string para1="frect",para6="10",para7="255",para8="10";
	int noOfWordsReaded=0,sequenceNo=0,geneTwoSeqNO,calculate,beginNum,endNum;

	ifstream in(inputFilePath);
	ofstream out(paraOutfilename.c_str());

	//write the name out

				out<<parameterStr<<"\n";	//put the parameter strings into the output file 
					
			}

		}
	}


}

But the if(calculate>=600) got some prob.. it end up filtering away those lines that is less then 600, but if i change the 600 to 400 it end up drawing all the lines.
sorry if u don't understand what i'm talking about....

CPP / C++ / C Code:
const string para6="10",para7="255", para8="10";
parameterStr=para6+" "+para7+" "+para8;

then now i want to put in a switch/if loop to change the para6,7,8
how do i do it??? got different color..
