Declare a single dimensional array of size 28 to store daily temperatures for the month of February. Using this structure, write a program to find:
- The hottest day of the month
- The coldest day of the month
- The average temperature of the month
Answer
import java.util.Scanner;
public class KboatFebTemp
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
double febTemp[] = new double[28];
int n = febTemp.length;
System.out.println("Enter Feb daily temperatures:");
for (int i = 0; i < n; i++) {
febTemp[i] = in.nextDouble();
}
double sum = 0.0;
int low = 0, high = 0;
for (int i = 0; i < n; i++) {
if (febTemp[i] < febTemp[low])
low = i;
if (febTemp[i] > febTemp[high])
high = i;
sum += febTemp[i];
}
double avg = sum / n;
System.out.println("Hottest day = " + (high + 1));
System.out.println("Coldest day = " + (low + 1));
System.out.println("Average Temperature = " + avg);
}
}Output
