i will mark you brainliest and follow you if you give me a correct answer

Answer 1

Answer:

In this program, instead of using a while loop, we use a for loop without any body.

On each iteration, the value of num is divided by 10 and count is incremented by 1.

The for loop exits when num != 0 is false, i.e. num = 0.

Since, for loop doesn't have a body, you can change it to a single statement in Java as such:

for(; num != 0; num/=10, ++count);
