trouble finding the minimum value in a array

ryanmac75 (13)
Hello

I am having a issue with finding the lowest value in a array. For some reason it keep comes up with what the average is.

my input values are 3.1, 4.3, 2, 0.2, 1.2, 1.3, 4.5, 1.3, 2.2, 2, 1, 1.1
total comes out as 24.2
average comes out as 2.0
maximum comes out as 4.5
minimum comes out as 2.0 it should be 0.2

thanks in advance for helping me.

	}

	float total = 0;
	for (int count = 0; count < MONTHS; count++)
		total += rainFall[count];

	float average = total / MONTHS;

	

	cout << endl;

	cout << " Total rainfal:      " << total << endl;
	cout << " Average:            " << average << endl;
	cout << " Maximum:            " << max << endl;
	cout << " Minumum:            " << min << endl;

}

float fun(float rain)
{
	cout << " Enter the rainfall total for month one: " << endl;
	cin >> rain;
	
	return rain;
} Put the code you need help with here.

Total rainfall: 24.2

      Maximum: 4.5
      Minumum: 0.2
 
Exit code: 0 (normal program termination)

A small mistake here

for (num2 = 1; num2 < min; num2++)

use MONTHS instead of min
