Struggling with end of array for program

gem925 (14)
Add code to read 5 words from the Console (user input). Store these values into an array of string []. Make sure the string[] array is large enough to hold at least 6 values. Store the string constant “end_of_array” into the last element of the array. Using a do…while() loop, print out the 1st and 3rd letters of each word (two letters per line) using the substring function.

Any guidance would be greatly appreciated.

What have you done so far??

This is what I have done far:

//First, write a simple program that will read 5 numbers from the Console (user input). Store these values into an array of int []. Using the length of the array in a for() loop and decrementing the loop counter, write the array values in reverse order to the screen.


#include <iostream>
#include <string>

using namespace std;

int main()

{
int array[5];
int counter;
int i = 0;
int string[6];
char word;




cout << "Please enter five numbers: ";


for (counter = 0; counter < 5; counter++)
{
cin >> array[counter];

}

cout << endl;


cout << "Counting down the numbers: ";

for(counter = 0; counter < 5; counter = counter++)
cout << array[counter] << " ";

cout << endl;



cout << "The numbers in reverse order are: ";

for (counter = 4; counter >= 0; counter--)
cout << array[counter] << " ";

cout << endl;


//Next, add code to read 5 words from the Console (user input). Store these values into an array of string []. Make sure the string[] array is large enough to hold at least 6 values. Store the string constant “end_of_array” into the last element of the array. Using a do…while() loop, print out the 1st and 3rd letters of each word (two letters per line) using the substring function.

cout << "Please enter five words: ";

for (counter = 0; counter < 6; counter++)
{
cin >> string[counter];

}

cout << endl;
do
{
cout << "Print out 1st letter for each word: " << string << endl;

}while(


return 0;

}

Thank you so much for your help I just wish the book would show examples like this so I could understand it better.
