print(i)
i += 1
else:
print(0)

Solution
The program you provided is written in Python. Here's a step-by-step explanation of how it works:
-
The variable
iis initialized with a value of 0. -
The
whileloop checks if the value ofiis less than 3. If it is, it enters the loop. -
Inside the loop, it first prints the current value of
i. -
Then, it increments the value of
iby 1 using the+=operator. -
The loop then goes back to the condition check. If
iis still less than 3, it repeats steps 3 and 4. Ifiis not less than 3, it exits the loop. -
After the loop, the
elsestatement is executed. This happens when thewhileloop condition is no longer true. It prints the value 0. -
The final output of the program will be:
0
1
2
0
The numbers 0, 1, and 2 are printed from the while loop, and the final 0 is printed from the else statement after the loop.
