need some help with while loop

i got this program i gotta write that reads in characters one at a time and print them out and i have to use the while loop. i tried all sorts of things but its not working. i think its the criteria im setting to get it matched is the problem. can any one help me. the code is below. by the way i hve to print out the characters in hex,octal,and decimal..
also it has to be simple code like only using the while loop and not arrays. im currently working on this if anyone can help me il appreciate it,

Code:

---

#include <stdio.h>
      9 int main()
    10 {
    11 char ch;
    12 fprintf(stdout,"Enter a character: ");
    13 while (fscanf(stdin,"%c", &ch)==1);
    14 {
    15 fprintf(stdout,"Character    Hex    Octal  Decimal \n");
    16 fprintf(stdout,"%c          %5x    %5o      %5d  \n",ch, ch, ch, ch);
    17 }
    18  return 0;
    19  }

---

> while (fscanf(stdin,"%c", &ch)==1);

See that ";" over there at the end of the line? Take it out.

to get you started, how about getting rid of the semi-colon at the end of this?

Quote:

---

13 while (fscanf(stdin,"%c", &ch)==1);

---

the semicolon causes nothing to be executed inside of the while loop

instead, do something like

Code:

---

    while( foo < bar){
        ...do some important stuff...
    }
    ... do more important stuff...

---

i got it after like 2 hours thanx for the suggestion i overlooked that too.lol heres what i got

Code:

---

#include <stdio.h>
int main()
{
  char ch;
  int count;
  count=0;
fprintf(stdout,"character    hex    octal    decimal\n");
 
while(fscanf(stdin,"%s", &ch)==1)
    {count++;

fprintf(stdout,"%5c        %3x      %3o        %3d      \n",ch,ch,ch,ch);
      }
fprintf(stdout,"You've read %d characters\n",count);
  return 0;
  }

---

Code:

---

fprintf(stdout,"You've read %d characters\n",count);

---

->

Code:

---

printf("You've read %d characters\n",count);

---

Code:

---

char ch;
while(fscanf(stdin,"%s", &ch)==1)

---

ch isn't a string! Use %c and scanf, or getchar():

Code:

---

while((ch = getchar()) != EOF)

---

And while you're at it, change ch to an int if you're going to be testing it for EOF. ;)

Just testing you, Quzah. :D
