The main() function stores a list of favorite numbers in an array and prints them using a for loop.

• Declares an integer array favoriteNumbers with 3 elements {7, 21, 42} (these can be changed).

• Prints the heading "My favorite numbers are:" using cout.

• Uses a for loop that runs 3 times (i = 0; i < 3; i++), printing each element of the array one by one.

• The output displays all the numbers stored in the array, each on a new line.

• Ends with return 0; to signal successful program completion.
