Real-Life Examples

Real-Life Example

To illustrate a practical application of arrays, let’s develop a program that computes the average age of a group of individuals:

Example

// An array storing different ages
int ages[] = {20, 22, 18, 35, 48, 26, 87, 70};

float avg, sum = 0;
int i;

// Get the length of the array
int length = sizeof(ages) / sizeof(ages[0]);

// Loop through the elements of the array
for (int i = 0; i < length; i++) {
sum += ages[i];
}

// Calculate the average by dividing the sum by the length
avg = sum / length;

// Print the average
printf(“The average age is: %.2f”, avg);

In this example, we construct a program to determine the youngest age among a set of ages:

Example

// An array storing different ages
int ages[] = {20, 22, 18, 35, 48, 26, 87, 70};

// Get the length of the array
int length = sizeof(ages) / sizeof(ages[0]);

// Create a variable and assign the first array element of ages to it
int lowestAge = ages[0];

// Loop through the elements of the ages array to find the lowest age
for (int i = 0; i < length; i++) {
if (lowestAge > ages[i]) {
lowestAge = ages[i];
}
}
