 # Question: How Do You Store Digits Of A Number In An Array?

## How do you reverse an array?

Step by step descriptive logic to reverse an array.

Input size and elements in an array.

Store it in some variable say size and arr respectively.

Declare another array that will store reversed array elements of original array with same size, say reverse[size] ..

## How do you find the last two digits of a number?

Process to calculate last two digits of a product: Units digit of A x B is given by the units digit in the product of b and d. If the product of b and d results in more than 1 digit, the excess digit will be carried over to the left. i.e in 1439 x 2786, multiply 9 and 6 which gives 54.

## How do you reverse an array without using another array?

Reverse an array of characters without creating a new array using java. If you want to reverse int array, you have to change public static void reverseArray(String[] array) as public static void reverseArray(int[] array) and String temp as int temp . and so on.

## How do I reverse an array in Numpy?

The most efficient way to reverse a numpy array is to use reversed_arr when you are creating a view into the original array. You can then change the original array, and the view will update to reflect the changes.

## How do you convert a number to an array?

Try this on for size.public static int[] IntToIntArray(int num)if (num == 0)return new int { 0 };List digits = new List();for (; num != 0; num /= 10)digits. Add(num % 10);int[] array = digits. ToArray();System. Array. Reverse(array);More items…•

## How do you extract digits from a number?

Split number into digits in c programming, Extract digits from integer in c languageint num,temp,factor=1;printf(“Enter a number: “);scanf(“%d”,&num);while(temp){printf(“Each digits of given number are: “);while(factor>1){printf(“%d “,num/factor);

## How do you count numbers in an array?

Answer: Use the PHP count() or sizeof() function You can simply use the PHP count() or sizeof() function to get the number of elements or values in an array. The count() and sizeof() function returns 0 for a variable that has been initialized with an empty array, but it may also return 0 for a variable that isn’t set.

## How do I reverse an array order in C++?

Algorithm to reverse an arrayFirst of all take number of elements as input from user. Let it be N.Then ask user to enter N numbers and store it in an array(lets call it inputArray).Declare another array of size equal to input array.Using a for loop, copy elements from inputArray to reverseArray in reverse order.

## How do I convert a number to an array in C++?

The easiest way I can imagine now is: char array; int number = 123456; memset(array, 0x00, sizeof(array)); sprintf(array, “%d”, number); Additionally you can convert each digit to int just subtracting the char value by 0x30.

## How do you extract the first digit of a number?

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. At the end we are left with the first digit.

## How do you find the nth digit of a number?

If you wanted an iterative approach: 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.
