Question

This assignment will give you more experience on the use of loops

In this project, we are going to compute the number of times a given digit D appears in a given number N.   For example, the number of times 5 appears in 1550 is 2.  The number of times 0 appears in 1550 is 1.  The number of times 3 appears in 155 is 0.  Etc.

Task

Your task is to implement the following the algorithm.

1- initialize a counter to 0

2- decompose the number N into its corresponding digits by calculating quotients and remainders of dividing it by 10

3- increment the counter each time the digit D appears

Example:

Given the number  N = 1550 and the digit D = 5:

Calculated Digit

Counter

Given the number  N = 96395 and the digit D = 9:

Calculated Digit

Counter

Project Description / Specification

1. Prompt the user for the given number and the given digit.

2. The program should have error checking to make sure the user inputs are valid. For example, if a user gives non-integer inputs, notify the user that the inputs are incorrect and prompt again.

3. Decompose the number in a loop and increment the counter within the loop as described in the example above.

Sample Interaction:
