C++ Arrays Real-Life Examples
Real Life Example
To demonstrate a practical example of using arrays, let's create a program that calculates the average of different ages:
Example
// An array storing different ages
int ages[8] = {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 age : ages) {
sum += age;
}
// Calculate the average by dividing the sum by the length
avg = sum /
length;
// Print the average
cout << "The average age is: " << avg
<< "\n";

And in this example, we create a program that finds the lowest age among different ages:
Example
// An array storing different ages
int ages[8] = {20, 22, 18, 35, 48, 26,
87, 70};
int i;
// 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 age
: ages) {
if (lowestAge > age) {
lowestAge =
age;
}
}
// Print the lowest age
cout << "The lowest
age is: " << lowestAge << "\n";
