Let's say you put your input in 'acBuffer[]'
:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
 
int iCount = 0;
 
for (iCount = strlen(acBuffer); iCount => 0; iCount--)
{
    printf("%s\n", acBuffer);
    acBuffer[iCount] = '\0';
}
 
int iCount = 0;
 
for (iCount = strlen(acBuffer); iCount => 0; iCount--)
{
    printf("%s\n", acBuffer);
    acBuffer[iCount] = '\0';
}

Or something like that.

cheers Niek

ps. Don't forget to include string.h

(i forgot to mentioned that i need this on C)!!!!!

this is my prog so far:

#include <stdio.h>
#include <string.h>
main(){
char acbuffer[50];
int icount=0;
clrsrc();
printf("Enter Any Word: ");
scanf("%s", &acbuffer);
strlen(acbuffer);
for (icount=strlen(acbuffer); icount>0; icount--)
{
printf("%s\n", acbuffer);
acbuffer[icount]='0'; <======= right here i think need to decreased my word some how ..
}
getche();}

Need to decrease any word. EX. Hello then i will be Hell, Hel, He and so on until i doenst have any letters on it then the prog is terminated.

read closer:

i said: acBuffer[iCount] = '\0';

you typed:

acbuffer[icount]='0';

your output was:

hello
hell0
hel00
he00
h000
0000

The latest version of the compiler can be downloaded from here:
http://www.borland.com/downloads/download_cbuilder.html

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
#include <stdio.h>
int main ()
{
   int a, i;
   for (a=5; a>0; a--)
   {
      for (i=a; i<5; i++)
      {     
          printf("x" );
      }
      printf("y\n");
    getchar () ;
}
#include <stdio.h>
int main ()
{
   int a, i;
   for (a=5; a>0; a--)
   {
      for (i=a; i<5; i++)
      {     
          printf("x" );
      }
      printf("y\n");
    getchar () ;
}

Your prev code was full of non standard functions. Dont use functions like clrscr ( ) and dont use non standard headers like #include <conio.h>

I don't accept change; I don't deserve to live.

THe code which you have attempted, makes use of "scanf" for accepting string or char data which normally is not advised since it leaves the input stream dirty and which will cause behaviour which u had not expected.
Better use the technique which i have used while accepting char data and it will always work like a breeze.
Also you have used only one for loop to implement your logic which is not correct since you normally need one for controlling the number of chars to be printed and the second one to actually print characters.

Try somehting like this:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
int main()
{
    int i = 0, j = 0 ;
    char buffer[BUFSIZ] = {'\0'} ;
    printf ("Enter the string you want to display: ") ;
    fgets (buffer, BUFSIZ, stdin) ;
    if (buffer[ strlen (buffer) - 1 ] == '\n')
        buffer[ strlen (buffer) - 1 ] = '\0' ;
 
    for ( i = strlen (buffer) ; i > 0; --i)
    {
        for ( j = 0; j < i; ++j)
        {
            putchar (buffer [j]) ;
        }
        putchar ('\n') ;
    }
   return 0 ;
}
int main()
{
    int i = 0, j = 0 ;
    char buffer[BUFSIZ] = {'\0'} ;
    printf ("Enter the string you want to display: ") ;
    fgets (buffer, BUFSIZ, stdin) ;
    if (buffer[ strlen (buffer) - 1 ] == '\n')
        buffer[ strlen (buffer) - 1 ] = '\0' ;

    for ( i = strlen (buffer) ; i > 0; --i)
    {
        for ( j = 0; j < i; ++j)
        {
            putchar (buffer [j]) ;
        }
        putchar ('\n') ;
    }
   return 0 ;
}
