find the minimum value entered while using infinite loop c++

Question

My task is to find the minimum number between n input values that the user should enter in an infinite loop until a certain number or character is entered to stop the loop.

The problem that I am facing is, I can't get the condition that tests the input to see which of the entered numbers is the smallest to work. Also, a second problem is, I want to end the loop with a char not an int, but I don't know if that is even possible.

I searched online but I can't find any answers.

Side note: I am new to C++. I am using Borland C++ v5.02.

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

int I, min =0;
cout<<"Enter a number :";

do{
    cin >> I;
    if (I < min){
        if (I > 0){
            min = I;
        }
    }
}while (I > -1);

cout << min;

Answer 1

the problem with the code was with the header I couldn't find a one that was working with my compiler Borland v5.02 c++ but thanks to @JerryJeremiah he leads me to it.

also, I redeclared the min =INT_MAX; because I am using this code in a loop.

the code is working with me now.

#include <iostream>
#include <conio.h>
#include <limits.h>
int main()
{
     int I, min =INT_MAX;

     cout<<"Enter number of input :";

            do{
              cin>>I;
                if (I<min ){

                    if(I>0){
                         min =I;
                    }
                }

                }while(I>-1);

           cout<<min;
         min =INT_MAX;
         getch();
}
