Pro-Tips💡

This program uses a for loop to iterate from 1 to 50, and at each iteration,

it prints “Mystery series number ” followed by the current iteration number.

The std::cout is used to print the output to the console, and std::endl is used to add a new line after each printed number.

The return 0; statement at the end of the main function tells the operating system that the program has successfully executed.
