How do you find the second digit of a number?

3 Answers. You can do it by dividing by ten and then taking the remainder of division by ten: int second = (number / 10) % 10; In general, you could think of integer-dividing by a k -th power of ten as of dropping k least significant digits.

How do you find the first digit of a number?

Logic to find first digit of a number

1. Input a number from user. Store it in some variable say num .
2. Copy the value of num to some temporary variable say first = num .
3. Divide first by 10 , till first >= 10 .
4. Finally you are left with first digit in first variable.

How do you find the second last digit of a number?

Determining the second last digit and the last two digits

1. The second last digit always depends on the last two digits of the number so anything before that can be easily neglected.
2. We first convert the number in such a way that the last digit of the base becomes 1.
3. Last digit of (Second last digit of base) X (Last digit of power)
4. Let us look at few examples.

How do you add the first and last digit of a number in C++?

Logic to find sum of first and last digit using loop

1. Input a number from user.
2. To find last digit of given number we modulo divide the given number by 10 .
3. To find first digit we divide the given number by 10 till num is greater than 0 .
4. Finally calculate sum of first and last digit i.e. sum = firstDigit + lastDigit .

How do I get the digit of a number in Python?

This can be done quite easily if you:

1. Use str to convert the number into a string so that you can iterate over it.
2. Use a list comprehension to split the string into individual digits.
3. Use int to convert the digits back into integers.

How do you find the last digit of a number?

To find last digit of a number, we use modulo operator %. When modulo divided by 10 returns its last digit. To finding first digit of a number is little expensive than last digit. To find first digit of a number we divide the given number by 10 until number is greater than 10.

How do you find the nth digit of a number?

4 Answers. Loop n times, each time assigning to the number variable the result of dividing the number by 10. After the loop, the nth digit is the remainder of dividing the number by 10. FYI The remainder operator is % , so eg 32 % 10 = 2 , and integer division drops remainders.

How do I get the first digit of a number in C++?

First make a double variable in which the number is saved. Then divide that number by 10 in a loop to make the number continuously lose a digit, until it is a 1-digit number. cast the double variable to int to round it down. The result will then be the previously first decimal digit.

How do you find the middle digit of a number?

The one thing you can: compute the length (number of digits) within your number upfront, to avoid "iterating" the number twice - so you can determine if that number of digits is even or odd without "iterating" the number: int n = 1234; int length = (int)(Math. log10(n)+1); should give you 4 for 1234, and 5 for 12345.
