Thread: How can I change word endings?

Hi!


Sorry if my question sounds naïve but is it possible to create a programme which would detect and change word endings? I would like to write a simple verb conjugator, i.e.:


If you enter a word ending with AAA then I would like the programme to show, say, six modified words:

1. Word with the replaced ending, for example QWERTYAAA changes into QWERTYBBB
2. QWERTYAAA changes into QWERTYCCC
3. QWERTYAAA changes into QWERTYDDD

etc.


Is it possible to do it? If so, how? Your help is very much appreciated!

Thank you so much for your help!

This is my code:

Code:

#include <iostream>
using namespace std;


int main()
{
	char str[50];
	
	cout << "Please enter your word: ";
	cin >> str;
	cout << "This is your word: ";
	cout << str;


	
	return 0;
}

What should I do now?

Thank you for your help. I've already changed that and now my code is:

Code:

#include <iostream>
#include <string>


using namespace std;


int main()
{
    std::string word;
    
    cout << "Please enter the word: ";
    cin >> word;
    cout << "This is your word: ";
    cout << word;
    
    return 0;
}

I don't know, however, what member functions I should use to detect the endings and change them. Could you please provide me with more guidance?

Probably I'm doing something wrong but when I enter string substr (size_t pos = 3, size_t len = 3) const; into my code there's an error stating that "non-member function cannot have cv-qualifier".

It seems to me, at least from the description, that I can't use this to find and change the ending. How can I know the position of the first character? I want the program to check if the word ends with, let's say, aaa. If it does, then I want the program to change it into bbb. Finding the first "aaa" in the word would be useless as the word could possibly begin and end with "aaa" (aaacccaaa). Also I don't know the length of the word so I am not sure if specifying the exact position of suffix in size_t pos=x would solve the problem. I am confused.

Thank you, I'll read about them.
