Can somebody simply the function for me plz.
Thanks

if you can't use standard C function strcat() then your function looks ok to me. But you could also use pointers

void concatString(char *szTarget, const char* szSource)
{
     while( *szTarget ) 
           szTarget++;
     while( *szSource )
          szTarget++ = *szSource++;
     *szTarget = 0;
}
