    Q and A program

    hi, i am a beginner at C ++ programming (actually i just started today) but i got the hang of it pretty quick. i am now currently making a program in which i will input strings and the program will respond to my question. my question is how to keep the console window from closing after every question and answer. Right now i am able to ask a question and get a response, but only once. in order to ask a different question i have to reopen the program and type my question again. is there anyway i could just keep inputing strings until i want to manually close the console by closing the window?

    Code:
    #include <iostream>
    #include <cstring>	
    
    
    using namespace std;
    		
    int main()                            
    {
      char quest [100000]; 
      
      cout<<"Please input your question: ";    
      cin.getline ( quest, 50, '\n' );                          
      
      if ( strcmp ( quest, "how old am i?" ) == 0 ) 
        cout<<"xxx\n";
      
      else if ( strcmp ( quest, "what is my name?" ) == 0 )            
         cout<<"xxx\n";      
         
      else if ( strcmp ( quest, "what is the capital of xxx?" ) == 0 )            
         cout<<"xxx\n";     
         
      else if ( strcmp ( quest, "who is the best xxx?" ) == 0 )            
         cout<<"xxx\n";
         
      else 
        cout<<"I only answer to xxx\n";
        
      
      cin.get();

    So, have you learned loops yet?

    Well, write a program that loops and prints "hello world" in a loop. On each iteration, ask the user if he or she wants to quit. If the user enters yes (e.g., the letter 'Y' or 'y'), then quit. If not, continue with the next "hello world" iteration.

    A slightly more challenging variant of this is to only accept 'Y', 'y', 'N' and 'n' as valid input. If the user enters invalid input, continue asking if the user wants to quit (without printing the next "hello world").

    When you have finished this exercise, you would have a better idea of how to apply this to your current program.

    till u type quit u will be asked questions
    Code:
    #include <iostream>
    #include <cstring>	
    
    using namespace std;
    
    int main()
    {
    	char quest [100000];
    
    	while (1)
    	{
    		cout<<"Please input your question: ";
    		cin.getline(quest, 50, '\n');
    
    		if (strcmp(quest, "how old am i?") == 0)
    			cout<<"old xxx\n";
    
    		else if (strcmp(quest, "what is my name?") ==0)
    			cout<<"name xxx\n";
    
    		else if (strcmp(quest, "what is the capital of xxx?") == 0)
    			cout<<"capital xxx\n";
    
    		else if (strcmp(quest, "who is the best xxx?") == 0)
    			cout<<" best xxx\n";
    
    		else if (strcmp(quest, "quit") == 0)
    		{
    			cout<<"bye...";
    			return 0;
    		}
    
    		else
    			cout<<"I only answer to xxx\n";
    
    	}
    
    }

    Thanks alot you guys, Does anyone know how i could include a time/date or location Q and A. I know java has applets for that type of thing, i found similar stuff for C++ but how do i include it in my program? Thank you in advance

    EDIT*, i resolved the time/date issue, any ideas on location?

    well i solved the issue of asking a questions about the time and date and getting an up to date answer. But i still can't find a code that will allow me to determine my current location based on my ip address. I mean there are alot of pop ups and online ads that display your city's name depending on your ip address but i don't know if its possible to incorporate that into a C++ program.

    i tried to use this but since its in chinese i didnt know how and it ended up not working:
    http://www.deanlee.cn/programming/co...phic-location/


    EDIT: also, if there is ANYONE amazing enough to figure out a way in which i could type a term into the console and i would be responded with a at least a partial definition/info from wikipedia or any other online encyclopedia straight into my console, (Artificial intelligence using information from wikipedia) that would be insanely cool. Is this even possible or is it just a crazy dream?

    It's possible, but it's no small project. You'd need basic understanding of HTTP, an Networking library, and and HTML parser for starters.

    That'll at least get you the information. Trying to interpret for to create AI is a nother challenge entirely.
    It is too clear and so it is hard to see.
    A dunce once searched for fire with a lighted lantern.
    Had he known what fire was,
    He could have cooked his rice much sooner.

    Or, if he only needs a definition, he could use 'DICT'.

    Yea... Give me a break; I get bored cataloging inventory.

    Yea... bored... not completely insane.

    You'll actually have to insert tests if you want to find problems.
