Question

write a program to input an integer number or double digits number or triple digits number or higher digits number​

Answer 1

Answer:

We know that all the numbers are formed with the digits 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0. Some numbers are formed with one digit, some with two digits and some with many digits.

(i) There are 9 numbers of one digit. The smallest one-digit number is 1 (one) and greatest one-digit number is 9. All the digits become numbers when used as a number.

(ii) There are 90 numbers of two digits. The smallest two-digit number is 10 and greatest two-digit number is 99. In a two-digit number, one digit is placed at ten’s place and the other at one’s place.
