    This seems to be solved

    I'm not familiar with how C++ handles this, and it seems atoi doesnt really do what I'm looking for, unless I'm just overlooking something.

    #include <iostream>
    #include <cstdlib>
    
    using namespace std;
    
    int main()
    
    {
    char a[2];
    a[0]='3'; a[1]='1';
    cout << a[0] << " line 1 " << endl;
    cout << a[1] << " line 2 " << endl;
    cout << a[0] + a[1] << endl;
    return 0;
    }
    
    
    


    Hi, I know you posted something that 'works' but in case you don't really understand why, I thought I'd reply.

    when you type a[0] = '3' you're assigning a[0] with the value 51. If you check out an ascii table, you can see that the value 51 maps to the character '3'. So you've said

    a[0] = 51.

    In this case a[1] = 49

    so in your cout statement you're summing 51 with 49.

    In your solution you are subtracting the value 48 ('0' = 48 see ascii table)

    so

    51 - 48 = 3
    49 - 48 = 1

    Hope that clarifies the why.

    You are missing an opening curly brace after int main().

    I encourage you to use proper indentation which would highlight this issue a lot.

    You should also consider upgrading your compiler. Dev C++ is now very old. For C++ nowadays I recommend either CodeBlocks or Visual C++ Express (both are free)

    Yes I missed those things (like a semi-colon after the for loop etc..) while pating the code here..The complete code was something of this sort
    #include <stdio.h>
    #include <conio.h>
    #include <stdlib.h>
    
    int main()
    {
          int d,i;
          printf("Enter a number");
          scanf("%d",&d);
          for (i=2;i<=(d-1);i++)
          {
          if (d%i==0)
          printf("%d",i);
          }
         system("PAUSE");
          return 0;
    }
    


    Just as a follow up on indenting your code which Ryano121 recommended. I'd recommend indenting all your 'blocks.' You only seem to have taken Ryano advice and indented everything in your main function.

    
    int main()
    {
        int d,i;
        printf("Enter a number");
        scanf("%d",&d);
        for (i=2;i<=(d-1);i++)
        {      
            if (d%i==0)
              printf("%d",i);
        }      
        system("PAUSE");
        return 0;
    }
    
    
    


    Hopefully you can see how much easier it is to read the code.

    Ah a fellow northerner, welcome to Dream in Code!

    I work for the BBC in Salford Quays, Manchester. Are you studying at any unis around Manchester? I know Manchester uni is good for CS.


    Hi matey,

    I study at The University of Salford which is pretty darn close to the new BBC site.

    Thanks for the welcome :D
