Answer / abdur rab

#include <stdio.h>

void reverse ( char* cp_str )
{
char* cp_rev_ptr = NULL;
cp_rev_ptr = cp_str;
while ( ( cp_rev_ptr ) && ( *cp_rev_ptr != '\0' ) )
cp_rev_ptr++;
cp_rev_ptr--;

while ( cp_str < cp_rev_ptr ) {
*cp_str ^= *cp_rev_ptr ^= *cp_str ^=
*cp_rev_ptr;
cp_str++;
cp_rev_ptr--;
}
}

int main ( int argc, char* argv [] )
{
char array [] = {"dlroW olleH"};

printf ("\nBefore :%s", array );
