```
#include
#include
using namespace std;

const int SIZE = 20;

int main()
{
char string1[ SIZE ];
char string2[ SIZE ];
int result;

cout << "Enter two strings: ";
cin >> string1 >> string2;

// uses function strcmp to compare the two strings
result = strcmp( string1, string2 );

if ( result > 0 )
cout << '\"' << string1 << '\"' << " is greater than \""
<< string2 << '\"' << endl;
else if ( result == 0 )
cout << '\"' << string1 << '\"' << " is equal to \"" << string2
<< '\"' << endl;
else
cout << '\"' << string1 << '\"' << " is less than \"" << string2
<< '\"' << endl;

return 0; // indicates successful termination
} // end main
```
Enter two strings: green leaf
"green" is less than "leaf"
