C Program to Count Number of Digits in an Integer
Enter an integer: 3452
Number of digits: 4
The integer entered by the user is stored in variable n. Then the do...while loop is iterated until the test expression n! = 0 is evaluated to 0 (false).
After the first iteration, the value of n will be 345 and the count is incremented to 1.
After the second iteration, the value of n will be 34 and the count is incremented to 2.
After the third iteration, the value of n will be 3 and the count is incremented to 3.
After the fourth iteration, the value of n will be 0 and the count is incremented to 4.
Then the test expression of the loop is evaluated to false and the loop terminates.
