Solution

The output of the program will be "3".

Here's the step-by-step explanation:

  1. The program starts with the main function. This is the entry point of the program.

  2. Inside the main function, an integer variable 'i' is declared.

  3. The value assigned to 'i' is (1, 2, 3). This is a comma operator, which evaluates its operands from left to right and returns the value of the rightmost operand. So, the value of 'i' becomes 3.

  4. The 'cout' statement prints the value of 'i' to the standard output, which is typically the terminal or console. So, "3" is printed.

  5. The program ends after executing the main function.
