Finding the Minimum using a function

I need some help using functions. I wrote this code as if it was a regular program.

Code:

#include <iostream>
using namespace std;

int main()
{

int num, count = 0, flag = 10, MIN = 0;

    while( count < flag )
    {
    cout << "Enter a number: " << endl;
    cin >> num;

    if( num < MIN )

        MIN = num;

    count++;
    }

    cout << "The smallest number is " << MIN << endl;

}

Write a program that will ask for the 10 numbers. The program will use a function to find the minimum number.

This is what I am supposed to do. Not sure how to start doing it.

Create a function called "min" or something like that, that takes two numbers as parameters. Then have it return the smallest number of the two parameters.

Use a loop that gets input and compares the input with the currently stored minimum (use the min function for this). Exit the loop when you have compared ten numbers.

Code:

int num,MIN=0;
for(int count=0; count < 10; count++)
{
    cout << "Enter a number: " << endl;
    cin >> num;

    if( num < MIN )

        MIN = num;
}

if you initialize MIN to 0 - you never got the positive result...
you should start with INT_MAX (or with the first entered number)

Or rather, you should write down your algorithm on paper and analyze it. See if you can spot a problem in it.

I think I might be on the right track.

Code:

#include <iostream>
using namespace std;

int min(int find);

int main()
{
int find_min;
int new_min;

    cout << "Enter a number: " << endl;
    cin >> find_min;

    find_min = min(new_min);

    cout << "The smallest number is " << new_min << endl;

}
int min(int find)
{
    int num, count = 0, flag = 10, MIN = 0;

    while( count < flag )
    {
    cout << "Enter a number: " << endl;
    cin >> num;

    if( num < MIN )

        MIN = num;

    count++;
    }

    return MIN;
}

The only problem I am having is when it prints out the answer it says "The smallest number is 2147332096

Try printing find_min instead of new_min.

It works but am I supposed to have two

Code:

cout << "Enter a number: " << endl;
    cin >> find_min;

and

Code:

    cout << "Enter a number: " << endl;
    cin >> num;

Code:

#include <iostream>
using namespace std;

int min(int find);

int main()
{
int find_min;
int new_min;

    cout << "Enter a number: " << endl;
    cin >> find_min;

    find_min = min(new_min);

    cout << "The smallest number is " << find_min << endl;

}
int min(int find)
{
    int num, count = 0, flag = 10, MIN = 0;

    while( count < flag )
    {
    cout << "Enter a number: " << endl;
    cin >> num;

    if( num < MIN )

        MIN = num;

    count++;
    }

    return MIN;
}
