C++ Entering numerals of an integer horizontally

[whodgson]

The following code does everthing required except that because each numeral of the integer has to be entered individually the numbers appear in a vertical column. Question: is there a way of entering the numbers so that they appear on the screen in one row each having been entered individually?

int main ()
{
string s;
char c;
int sum=0,n=0,a[6]={0},num=0;
cout<<"Enter a 6 digit integer \n";
int i=0, fact=100000;
while(i<6)
   {cin>>n;
   a[i]=n;
   num+=a[i]*fact;
   fact/=10;
   i++;
   if(i>5) break;      
  }
cout<<"The integer entered is: "<<num;

if(num%3==0)cout<<" and is divisible by 3 (= "<<num/3<<" )";
else cout<<" and is not divisible by 3";

for(int i;i<6;i++)
 sum+=a[i];
cout<<"\nSum of numerals is: "<<sum; 
if(sum%3==0)cout<<" and is divisible by 3\n";
else cout<<" and is not divisible by 3\n";
cout<<"\n";
system("pause");
return 0;
}

i`ve modified the code to include this nexrInt() funct as follows:

int nextInt()
{ 
    int a[6]={0}; 
    char ch;
    int i=0;
    while (cin.get(ch))
       { 
        if (ch>= '0' && ch<='9')//next character is a digit
        a[i]=ch;
        i++;
        if(i>=6) break;
        }     
        for(int i=0;i<6;i++)
        cout<<a[i]<<" ";    
 }

/*
Enter a 6 digit integer 123698
49 50 51 54 57 56 //this should be same as input but..........
*/
I'm obviously doing something wrong and illegal which is probably the while arguement.

It's the cin.get() echoing the enter key you used to enter the character.

Maybe you could try getchar().

[Simonius]

That'll still have to same problem.
A possible solution might be a variant of gotoxy but that'll be a bit cumbersome and you'll have to take into account some constraints.

You will have to stop echoing the enter key. I don't remember if there is a way to do that.

You would have to play around with the console functions (assuming Windows) and change the way the console worked. And add in some additional code yourself. Have fun...

I don't know about the echoing thing, but your cramming a char into an int, thats not gonna work the way you want it to.
Say somebody puts in 9 - Ascii '9' isn't the same as int( 9 ) so when you do a[i] = ch your not storing 9, your storing the character '9', which has int value of 57.

Or maybe I'm confused...

Thank you for your comments--wish i had your insights.
I couldn`t see the wood for the trees.
This is what i finally came up with which works fine.

int intManip(int n)
{ int m=0,sum=0;
 int a[6]= {0};  
 for (int i=0;i<6;i++)       
    { a[i]=n%10;
      m=n/10;
      n=m;
      sum+=a[i];
    }
     return sum;
     
}

/*
Enter a 6 digit integer 369258

Sum of digits: 33
*/
Thank you all
