// An ___ storing different ages int ages[] = {20, 22, 18, 35, 48, 26, 87, 70}; float avg, sum = 0; // Get the length of the array int length = ages.length; // Loop through the elements of the arrayHow To Calculate the Average of Array Elements
Create a program that calculates the average of different ages:
Example
// An array storing different ages int ages[] = {20, 22, 18, 35, 48, 26, 87, 70}; float avg, sum = 0; // Get the length of the array int length = ages.length; // Loop through the elements of the array
for (int age : ages) {
sum += age;
}
// Calculate the average by dividing the sum by the length avg = sum / length; // Print the average System.out.println("The average age is: " + avg);
