With some slight modifications we can breeze through exercise 8. The instructions require us to use the natural <string> header for C++ string class objects. The key point here is that using string is simply just easier. Why you ask? Because we can now use ‘!=’ and other comparative operators to make our comparisons. See my solution below:
8. Write a program that matches the description of the program in Programming Exercise 7, but use a string class object instead of an array. Include the string header file and use a relational operator to make the comparison test.
#include <iostream>
#include <string>
using namespace std;
int main()
{
string input;
int words = 0;
string compare= "done";
cout << "Enter words (to stop, type the word done):" << endl;
cin >> input;
while(input != compare)
{
cin >> input;
words++;
};
cout << "You entered a total of " << words << " words " << endl;
cin.get();
return 0;
}

This seems to meet the criteria for exercise 9, chapter 5. Exercise 8 requires the use of the cstring header file and strcmp() function.
“//exercise8.cpp — chapter 5.
//Michael R.
#include
#include
int main()
{
using namespace std;
char words[200];
int wcount = 0;
cout << "Enter words, separated by spaces. Use done to stop counting words. Press enter to complete counting procedure." <> words;
}
cout << "You entered a total of " << (wcount -1) << " words.";
return 0;
}
"
The previous was my solution. If anyone knows how I can get rid of the second to last line code "(wcount -1)", please inform me.
I think you meant ch5e7 and ch5e8. Exercise 9 is totally different. I can’t tell what was left out, but we do need to be using C++ string class this time and the word done to stop reading. What I was getting at with the solution for exercise 8 is that we can now just use comparative operators on the strings.
Ahh, I think the difference is the edition of the book.
Whoah, the vital parts of my code didn’t paste well into my last reply. Sorry about that.
