cin.get(c)

[Nobody/Anonymous]

Hello, my name is Franjo and I have a little problem using Dev-C++. Some programs don't work. For example:

#include <iostream.h>
#include <stdlib.h>
#include <cstring>
using namespace std;
int main()
{
char* c;
while(cin.get(c))
{
if(c >= 'a' && c <= 'z')c+='A'-'a';//capitalize c
cout.put(c);
if(c=='\n')break;
}
      system("PAUSE");
      return 0;
}

After compiling, I get a whole bunch of errors. Do you know what's wrong? Greetings, Franjo

Wow, I found something!!!!  Woohooo!
You need to change

char* c

to

char c

This gets rid of your compile errors.  Now, I don't think the code is working right for you.  For me to input a character into the stream, I have to hit return, which seems to trip your exit logic.

I think you need to rethink that part of the design.
I am too fried, and I hate characters, and I am not the sharpest knife in this drawer anyway.

#include <iostream.h>
#include <stdlib.h>
#include <cstring>
#include <conio.h>

using namespace std;

int main()
{
  char c;
  while(true)
  {
    c = getch();

    if(c >= 'a' && c <= 'z')
    {
      c+='A'-'a';//capitalize c
      cout.put(c);
    }
    else //if c != any known letter a-z
      break;
  }
  system("PAUSE");
  return 0;
}

This works for me, but I do not know what you are trying to do.  To capitalize though, I would include ctype.h and use the toupper command.

eg:
     c = toupper(c);
     cout.put(c) //instead of      if(c >= 'a' && c <= 'z')
                                           {
                                             c+='A'-'a';//capitalize c
                                             cout.put(c);
                                           }

Have fun.
