Solution
The program you provided is written in Python. Here's a step-by-step explanation of how it works:
-
The variable
i
is initialized with a value of 0. -
The
while
loop checks if the value ofi
is 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
i
by 1 using the+=
operator. -
The loop then goes back to the condition check. If
i
is still less than 3, it repeats steps 3 and 4. Ifi
is not less than 3, it exits the loop. -
After the loop, the
else
statement is executed. This happens when thewhile
loop 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.
