#include <iostream>
#include <string>
using namespace std;
char * reverse (char *); //function prototype
int length(char *); //function prptotype

int main()
{
int i;
char *str = new char[6], *rev = new char[6];
cin >> str;
strcpy(rev,reverse(str));

cout <<"Original "<< str << " reverse " << rev << endl;
free(str);
free(rev);
return 0;
}

int length(char *s)
{
int i;
for (i=0; *(s+i)!='\0' ; ++i);
return i;
}

char *reverse(char *s)
{
char *t;
int i, n;
n=length(s);
t = new char[n];
for (i=0; i<n; ++i)
{
*(t+i)=*(s+n-1-i);
}
*(t+i)='\0';

return t;
}

/*based off of answer 8 i took this an intialized the
pointers so that it would run, and switched it over to the
C++ standard output commands. His algorithm was correct, he
just forgot to setup the memory*/
