i know i am posting it again but i am not getting any suggestion regarding the following coding....now i need to do this one using pointers::

CODE
#include <iostream.h>
#include <string.h>
void main()
{
     char str[20], str2[20];
     int a = 0;
     cin.get(str2, 20);
     strcpy(str,"");
     for(int b = 0; b < 20; b++)
     {
          if(str2[b] != ' ')
          {
               str[a] = str2[b];
               a++;
          }

This should serve your purpose..


CODE

#include<iostream.h>
#include<string.h>

void main()
{

char str[30]="harsha",str2[20]="kiran";
int len;
char*ptr,*ptr2;
ptr2=str2;
ptr=str;
len=strlen(str);
ptr=ptr+len;
ptr--;
while(*ptr2!='\0')
{
*ptr++=*ptr2++;
}
*ptr='\0';
cout<<str;

}
