How to Find Digit Frequency in a Number in C++
In this lesson, we write a C++ program that takes a digit and a number, then prints the frequency of that digit in the number.
For example:
If the user enters the number 1332333
And the wanted digit is 3
The output will be:
Digit 3 Frequency is 5 Time(s).
In this video, you will learn:
How to take a positive number from the user
How to take the wanted digit from the user
How to extract digits from a number using % 10
How to remove the last digit using / 10
How to compare each digit with the wanted digit
How to count the frequency of one digit in a number using C++
This lesson is about finding the frequency of one digit only.
In the next lesson, we will use the same idea to print the frequency of all digits in the number, not just one digit.
If you are learning C++ problem solving step by step, this lesson will help you improve your logic and understand how to work with digits inside numbers.
