How to call read and write the ayam.txt and itik.txt into one file.

which first i would like to cout the ayam.txt and then itik.txt.

Re: how to read many text file?
 

U use ifstream and ofstream that is to read u use ifstream and to write u use ofstream..... assuming that u have declared the ofstream and ifstream files but to make a long story short....

U have to declare ur ifstream and ofstream files.... u can achieve that by doing the ff

ifstream in_file;

and

ofstream out_file;

and then U need to open them that is reading and writting using

in_file.open("eyam.txt");

and

out_file.open("eyam.txt");

u use ifstream variable to read and ofstream's to write so U will have something like

out_file << number;

whatever u wana write and use in_file to read whatever u wana read

#include <iostream.h>

ofstream output_file("out.4", ios::app);

   public:      // public interfaces for this class



        MERGE_FILE(char *, int);        

        MERGE_FILE operator + (MERGE_FILE &); 





   private: // private var to be used by this class only 



        char inputs[20][10];  // char array to hold file inputs

        char in_file[10];            // array to hold input file name



}; //END OF CLASS INTERFACE





MERGE_FILE::MERGE_FILE(char * i_f, int x)

{

        ifstream input_file(in_file, ios::in);

        int i;

        if (strcmp(i_f, "empty")==0)

        {

                strcpy(in_file,"No input file");

        }

        else if (strcmp(i_f, "empty")!=0)

        {

                n=x; //number of inputs to read

                strcpy(in_file,i_f);

                for (i=0;i<n;i++)

                        input_file>> inputs[i];

                }

                output_file<<"INPUT FILE NAME IS "<<i_f<<"."<<endl;

                output_file<<"Read  "<<n<<" inputs "<<endl;

        }

        else {}         

}



MERGE_FILE 

MERGE_FILE::operator + (MERGE_FILE & other_obj)

{



        int i;

        MERGE_FILE temp_obj("empty",0);

        temp_obj.n =n + other_obj;

        for (i=0; i<n; i++)

        {

                 temp_obj.intputs= inputs[i];

        }

        for(i=0;i<other_obj.n;i++)

        {

                temp_obj.inputs[i+n]=other_obj.inputs[i];

        }

        output_file<<" Theres "<< n<< " inputs in first file"<<endl;

        output_file<<" Theres "<<other_obj.n<< " inputs in second file"<<endl;

        output_file<<" Total inputs equal "<<temp_obj.n<<endl;

        return temp_obj;

}

now all you need to do is save as an header file and initiate this class in your main file and it should merge your files, haven't tested but it's a start. so you work the bugs out
