Help for another program

[Androto]

does anyone know how to read in a steam of charactes, on after another, one at a time, and build a sentence out of them. Then print out the sentence, as well as a list of all the letters that appeared in the sentance as well as how many times they each appeare?

Is this what you mean?

#include <iostream>
#include <cstdlib>
#include <string>

using namespace std;

int main(int argc, char *argv[])
{
   string letters;
   string input;
   unsigned count(0);
   
   for(;;)
   {
      //Use getline so spaces and tabs are counted in.
      getline(cin, input, '\n');
      if(input[0] == '@') //@ terminates the input sequence.
         break;
      else
      {
         //Add only ONE single letter. Ignore the rest.
         letters+=input[0];
      }
   }
   cout<<letters<<endl;

   system("PAUSE");
   return 0;
}

If so, then try the rest of your assignment for yourself first. It's a nice excercise.

what does

for(;;)

mean?


what does

getline(cin, input, '\n');

mean? i've never used getline before.



don't understand this part either:

if(input[0] == '@') 
         break;
      else
      {
                  letters+=input[0];
      }
   }

i tried running the program, and all i got was a empty window.

[Valmont]

Then study this part from your books. These are the very basics. If you can't figure out what they all mean, then you're not ready for this particular assignment to start with.
I am tired and it is bloody late here. It is almost today in fact. Tomorrow I *might* be answering this. I gotta go now zzzZZZzz

Offcourse you got an empty window.
You wanted to input a stream char by char. So I assume you need to enter char by char. When you are done entering the individual characters, enter @ and <enter>. Then see what happens.

[Androto]

k, but when you get back tomorrow, you'll know that i don't have any books.

[Valmont]

Goto http://www.cplusplus.com/doc/tutorial/ and start learning

[Androto]

i'll take a look at the site.

which time zone do you live in?

[Valmont]

Usually CET but at the moment GMT.

[Androto]

when i ran the progam and typed in random letters followed by the @ on the next line, all it did was give me the first letter of the string.

[Valmont]

No.
Add ONE letter PER line!
On the last line enter a @ .

[Androto]

is there a way for the person running the program to just type in the name, then when the hit enter (i'm guessing you have to use the getline thing for this part) it says how many times each letter appears (I think i'll have to use an array for this part)?

[Valmont]

Yes offcourse there is a way. You gave the solution basically yourself. I'll do it later. In the mean time see how far you can get.

[Androto]

would i be able to use this in it, or would this be wrong?

int main()
{
char sentance[x];
string x;
cin >> sentance[x];
....
}
