Count Digits in Python

In this program that I wrote will ask the user to give a string which contains a digits and then the program will count the number of digits in a giving string or sentence using Python programming language. I am using Pycharm as my text editor in writing this program. I hope you will learn something in this sample program.

I am currently accepting programming work, IT projects, school and application development, programming projects, thesis and capstone projects, IT consulting work, computer tutorials, and web development work kindly contact me at the following email address for further details. If you want to advertise on my website kindly contact me also in my email address also. Thank you.

Plus 10, 100, and 1000 Methods in Java

Machine Problem

Create a Java program that would ask an integer from the user. This should be performed by the main method. Construct three (3) methods named showNumberPlus10(), showNumberPlus100(), and showNumberPlus1000(). Each methods should perform the task its name implies. Called the methods after the user input to display three (3) outputs in separate lines.

Sample Program Output

Enter an Integer : 20

20 plus 10 is 30.

20 plus 100 is 120.

20 plus 1000 is 1020.
