H_4.cpp

//The modulo operator, %, returns the remainder of a division. For example, 4 % 3 = 1 and 12 % 10 = 2. The ordinary division operator, /, returns a truncated integer value when performed on integers. For example, 5 / 3 = 1. To get the last digit of a number in base 10, use 10  as the modulo divisor. 

//Task

//Given a five digit integer, print the sum of its digits.
//Input Format
//The input contains a single five digit number, .
//Constraints
//10000<=n<=99999
//Output Format
//Print the sum of the digits of the five digit number.
//Sample Input 0
//10564
//Sample Output 0
//16
