Solution

The output of the program will be 10.

Here's the step-by-step explanation:

  1. The program starts with the initialization of the variable sum to 0.

  2. Then, a for loop is started with two variables i and j, both initialized to 0.

  3. The condition for the loop to continue is i < 5 & j < 5. The & operator is a bitwise AND, which means both conditions have to be true for the loop to continue.

  4. Inside the loop, sum is incremented by i.

  5. After the loop body, i is incremented by 1 (++i), and j is set to i + 1.

  6. The loop continues until i < 5 & j < 5 is no longer true. This happens when i becomes 4 and j becomes 5.

  7. The values added to sum during each iteration of the loop are 0, 1, 2, 3, and 4.

  8. Adding these numbers together gives the final value of sum, which is 10.

  9. This value is then printed to the console.
