int _tmain(int argc, _TCHAR* argv[])

int i = 0;
int number;
int resto[10];
int sum = 0;
cout << "input number\n";
cin >> number;
while (number > 0)
{
resto[i] = number%10;
sum = sum + resto[i];
number = number/10;
i++;

There is actually a very simple solution to this problem. First, you are trying to do two things here:

```
1. Split an input number into separate digits.
2. Add the digits together.
```

First of all, I would not recommend putting your input into an int type. If you do this, you have to split each digit using modular arithmetic. While this is mathematically elegant and very pleasing aesthetically, it is not the optimal solution here. Instead, one could store the input as a string. In this case, each character can then be interpreted as a digit in and of itself and processed accordingly. Then, in one pass, one could output each digit and accumulate a running sum. The method is summarized here in pseudocode:

```
set integer sum = 0
get input -> store in string s
for each character c in s:
output c
sum = sum + integer( c )
output sum
```

The tricky part here is converting each character to an integer. Fortunately, this is very simple in c++: `int i = c - '0'`

This works because numbers in the ascii table are sorted in ascending order. Furthermore, chars are actually integers, so we can perform arithmetic on them. So, any numerical character minus the zero character results in the integer that the character represents: `7 == '7' - '0'`

Using this method, the algorithm you are trying to build can be defined in a concise main function taking only 13 lines of code ( including separate lines for each curly brace ). Try it out if you would like, and we can see how it works for you.

>>**I want to my program to prompt user to input a number with three or more integers **

You know how to get the user input into a variable right ?

```
int var1 = 0 , var2 = 0, var3 = 0;
cin >> var1 >> var2 >> var3; //get 3 inputs from the user
```

>>**I need the program to output a space between each numebr**

You know how to output numbers to the screen dont you?

```
cout << 1; //output the number 1
cout << " "; //output the string space
cout << 2 << " "; //output the number and put a space after the number
```

>>**then i also need to output the sum of these number so 3+3+3+4?**

You know how to add the variables dont you ?

```
int var1 = 0, int var2 = 0, int var3 = 0; //create variables
cin >> var1 >> var2 >> var3; //get inputs
int sum = var1 + var2 + var3; //add the results
//print the sum
cout << var1 << " + " << var2 << " + " << var3 << " = " << result;
```

Next time just take it part by part and try the problem.

My guess is this is exactly what the instructor wants. It teaches a technique very important to computing.

Read a value into an integer.

Use the modulus operator % and division to split the input into separate values, an array would work best.

Won't work. Try it with an input of 321.

Well i figured out what to do in order to accomplish what i needed the input needed to be a string

here is the program working YEP!

```
#include "stdafx.h"
#include<iostream>
#include<sstream>
using namespace std;
int main()
{
//Declear Variables
int num0 = 0;
int sum = 0;
string b = "";
//display Three or more numbers section
cout<<"Enter three or more number (no dcimals): "<<endl;
cin>>num0;
if ( num0 < 0 )
num0 = -num0;
stringstream ss;
ss << num0; //convert to individual numbers
ss >> b;
for(int i = 0; i < b.length(); ++i)
{
cout<<b[i]<<" ";
}
cout<<endl;
//Calculate sum
while ( num0 != 0 ) {
sum += num0 % 10;
num0 /= 10;
}
cout<<"The sum is : "<< sum <<endl;
system("pause");
return 0;
}
//This worked out really nice yep so thats for the help peoples loved that you are gave those speedy replies thanks again
