Part 2: Array, For Loop and Math Operation
Creating new array based on user-defined size
Adds values into array provided by user
Part 1: Object and Classes
Enter airport name:
San Francisco
Enter first gate's name:
G97
Enter first gate's length in meters:
30
Enter second gate's name:
G98
Enter second gate's length in
30
Gate 1's name is: 697
Gate 2's name is: 698
Enter Gate 1's new name:
G99
Gate 1's name is now: 699
rs:
Iterating through the array and calculate the
sum of all values in the array
These are the final
output !
Part 2: Array, For Loops and Math Operations
Enter desired size of array:
10
Enter 5 integers to store into array:
The sum of all numbers in array is: 15
