Good day.

I started programming lesson recently. I have been using the C++. I know how to use pseudo code mainly. Again, I know how to use it for solving expressions and so on. I got hooked up when it came to encrpting just 10 words and I spent hours without success. The format I want to use is that in which each letter is replaced bythe next in the alphabet.
Again, I know of the flow-chart, connectors, loops etc but I couldnt find any shapes on the C++ work space. When I wentto microsoft word to copy the shapes, it was of no avail. A clarificartion will be highly appreciated! I see the surrounding quite programmy!

Shapes? Ideally, you could write your own encryption mechanism, pseudo code might look something like this:

cpp

function Encrypt
     read through inputted string/array
     for each element in the array
          change current item to next letter in the alaphbet, etc...
    print out encrypted array
    decrypt if you want (requires you to write that function as well
         will be the reverse of encrypt

If you want the user to enter a string then yes, you will need printf and scanf. What's with the shapes? If you want to display a flowchart you'll need a lot more for this program, specifically a API for the graphics. If you want to draw a flowchart on paper to outline program flow, then i would suggest looking online for some good information--there's lots of it out there.

To get a list of the basic 'shapes' and stuff just compile this....

CODE

#include <iostream>
using namespace std;

int main(void)
{
   for (int i = 0;i<255;i++)
   {
      cout << i << " : " << (char) i << endl; //Display the int value and the Char Value of the int
    }
   system("pause");  //So you can see the output
   return 0;
}


Its not a great code or anything but it will display the ascii table and the deci value.
Keep in mind there are white spaces included such as (char) 32 would be space, (char) 10 would be
'Return' ...ect.

If you want to keep it as simple as you can i would just use the ascii and have fun =)
