Objectives: Using C-Strings.

a program that asks the user to enter a series of single characters (alphabets and digits) with nothing separating them. Read the input as a c-string. Make sure you input no more than 15 characters.

The program should display the sum of all the single-digit numbers in the string. For example, if the user enters 25a1y4, the program should display 12, which is the sum of 2, 5, 1, and 4. Treat any non-digit character as a '0'

You may NOT use the cstring library with this program.

You may use the iomanip library to limit input. Hint: setw() can help

You can't use the isdigit() function
