Question

- I am having trouble with the headers

-Also if I remove the .h it doesn't allow the program to build, if kept it brings up warnings (Also clrcr is coming up undefined)

Q: How can I execute this program on unix using C++ language? (Unix doesnt like iostream.h)

Here is my source code:

#include<iostream.h>
#include<fstream.h>
#include<conio.h>

#include<stdlib.h>
int main()
{
clrscr();
long bin, dec = 0, rem, num, base = 1;
int i=0;
ifstream myReadFile;
myReadFile.open("text.txt");
char *output;
char mystr[999];
// if (myReadFile.is_open())
{
i=0;
while (!myReadFile.eof()) {

myReadFile >> output;

num = atol(output);

bin = num;
cout << bin;
while (num > 0)
{
   rem = num % 10;
   dec = dec + rem * base;
   base = base * 2;
   num = num / 10;
}

if(dec > 64 || dec < 91 || dec > 96 || dec <123)
{ mystr[i] = (char) dec;
   i++ ;}
* output =' ';
dec=0; base =1;
}
}
myReadFile.close();
cout << mystr;
return 0;
}

Explanation / Answer

use

#include <bits/stdc++.h>
using namespace std;

instead of

#include<iostream.h>
#include<fstream.h>
#include<conio.h>

#include<stdlib.h>

#include <bits/stdc++.h>  is basically a header file that also includes every standard library and stl include file.

use

system("clear");

instead of

clrscr();

Finally a suggession:

There is a better way and simple way to read data from a file.
You can replace

ifstream myReadFile;
myReadFile.open("text.txt");
char *output;

while (!myReadFile.eof()) {
myReadFile >> output;
num = atol(output);
}

BY
ifstream myReadFile;
myReadFile.open("text.txt");
while(myReadFile>>num){
//use num in here
}
