Assignment 6a (15 points] - Character and String related processing... Listed below are two interesting programming challenges that will require a bit of character and/or string related processing with functions. (Carefully read the specifications for each programming challenge and select ONE.) (1) Sum of Digits in a String Write a program that asks the user to enter a series of single-digit numbers with nothing separating them. Read the input as a C-string or a string object. The program should display the sum of all the single-digit numbers in the string. For example, if the user enters 2514, the program should display 12, which is the sum of 2,5, 1, and 4. The program should also display the highest and lowest digits in the string. It is recommended that you include a function such as int charToInt(char) The char Tolnt function accepts a char and returns the char's value as an integer digit. If the char is not a digit, the function returns 0. and Table 10-4 C-String/Numeric Conversion Functions (Hint: Refer to Table 10-1 Character Testing Functions in <cctype> in <cstdlib> Data Validation: Series of digits input should not include spaces and non digit characters. Sample screen output (user input is in bold): Enter a series of digits with no spaces between them. 1 2 3 4 5 Incorrect input....? Enter a series of digits with no spaces between them. 1234 4321 Incorrect input....? Enter a series of digits with no spaces between them. 1234 src Incorrect input....? Enter a series of digits with no spaces between them. srjc 1234 Incorrect input....? Enter a series of digits with no spaces between them. 987654321 The sum of those digits is 45 The highest digit is 9 The lowest digit is 1 Process returned 0 (0x0) execution time: 71.074 s Press any key to continue.

If you have any problem with the code feel free to comment.

Program

#include <iostream>
#include <string>

using namespace std;

int validateInput(string);
int charToInt(char);

int main()
{
string str;

//taking valid input
while(1)
{
cout<<"Enter a series of digits with no spaces between them."<<endl;
getline(cin, str);

if(validateInput(str) == 0)
cout<<"Incorrect input.....?\n\n";
else
break;
}

int num;
int sum =0;
int low = charToInt(str[0]);
int high = charToInt(str[0]);

//find high and low and calculating sum
for(int i=0; i<str.size(); i++)
{

num = charToInt(str[i]);

sum += num;

if(low > num)
low = num;

if(high < num)
high = num;
}

cout<<"The sum of those digits is "<<sum<<endl;
cout<<"The highest digit is "<<high<<endl;
cout<<"The lowest digit is "<<low<<endl;

return 0;
}

//for validating input
//return 0 when invalid
//return 1 when valid
int validateInput(string str)
{

for(int i=0; i<str.size(); i++)
{
if(str[i] < '0' || str[i] > '9')
{
return 0;
}
}
return 1;
}

//convert char to int
int charToInt(char ch)
{
int num = (ch - '0');
return num;
}
