X code keeps giving me an error saying iostream not found. What's the problem??



#import <Foundation/Foundation.h>
#include <iostream>
#include <conio>
class time
{
int hr,min,sec;
public:
time()
{
hr=min=sec=0;
cout<<"
Time reset to 00:00:00";
}
time(int h,int m,int s)
{
hr =h;
min=m;
sec=s;
cout<<"
Time set to specified value.";
}
void display()
{
cout<<"
Time set is # "<<hr<<":"<<min<<":"<<sec;
}
void add(time t1,time t2)
{
sec = t1.sec + t2.sec;
if (sec > 59)
{sec -=60; min++;}
min += t1.min +t2.min;
if(min>59)
{min-=60; hr++;}
hr += t1.hr + t2.hr;
}
};
void main()
{
clrscr();
time a(12,11,33);
time b(10,34,50);
time c;
a.display();
b.display();
c.add(a,b);
c.display();
getch();
}

there is NO way we could even try to help unless YOU provide the REQUIRED information

the very basic information is missing
things like

YOUR operation system ?
the version of said OS ?
the version of gcc ( if installed) ?
and whether or not the obj compiler is installed ?
the development librarys ?? -- are they installed??

a wild guess
install the development tools and headers for your OS
"libstdc"

Hi, welcome to LQ

Xcode is for Mac OSX only, so I guess you are not using Linux. If that's the case, then this is the wrong forum to ask that kind of question. Very few peoples around here use OSX. It might be a better idea to ask this on a MacOSX forum.

Looking at your code, this is closer to C/C++ than OBJC. So you would be better to use Objective C++ or C++ directly than trying to do that in OBJc. This might actually be your problem in the first place. OBJc is compatible with C, iostream is from C++. The C equivalent is stdio.h
