The program segment creates a string variable named "numbers" with the values "1492,1776,1945". It then creates a temporary string variable by splitting the "numbers" string using the comma character as the separator. The resulting "temp" variable will be an array of strings with the values {"1492", "1776", "1945"}.
The program then creates an integer array named "nums" with three elements, and uses a loop to iterate through the sub-strings in the "temp" array, converting them to integers and storing them in the "nums" array.
The program then adds two items to a list box, using indexes to access elements in the "nums" array. The first item added is "nums(1)", which has a value of 1776. The second item added is "nums.First", which is equivalent to "nums(0)" and has a value of 1492. Therefore, the resulting list box items will be "1776" and "1492".
