#include
#include
using namespace std;

int main()
{
string s[ 5 ]; // declare a string array

// loop to get user input
for ( int i = 0; i < 5; i++ )
{
cout << "Enter a word: ";
cin >> s[ i ];
} // end for

// use function rfind to find occurrences of "ay" or 'r'
for ( int j = 0; j < 5; j++ )
{
// does the word end in "ay" or 'r'?
if ( ( ( s[ j ].rfind( "ay" ) == s[ j ].length() - 2 ) )
|| ( s[ j ].rfind( "r" ) == s[ j ].length() - 1 ) )
cout << s[ j ] << endl; // if match, display it
} // end for
} // end main
