The code is not working to find the max min for only negative nos.

Sample Output:-

Enter the count of numbers you want to enter :3
Now enter the numbers : -4
-2
-3
The count of positive numbers is : 0
The count of negative numbers is : 3
The count of zeroes is : 0
The largest number is : -1 !!!The problem is here. Can you fix this.!!!
The smallest number is : -4

I don't want to use array in this program. So suggest me without using any array.

I want to find the largest and smallest number from user input values.
My program almost works fine.
If I input -4, -2, -3. The program shows -1 is the largest. This is not possible. the largest number is -2 but not -1. I just want to find the largest and smallest number among the list irrespective of negative or positive.

        int cnt_negative = 0 ;
        int cnt_zero = 0 ;

        int max_val = std::numeric_limits<int>::min() ;

Thanks for the program.
