Thread: Random Outputs.

Hey what if you need a program to randomly choose several funtions from a list. Sort of like a hello program that responds in different ways.

I was wondering how to do this.

You could make a random number and use if statements or a switch statement to call the functions. Give us an example and maybe we can help.

Well, I'm making a chat bot thing (in cmd promt) using Dev C++.

This is what I have:

Code:

cout << "what is your name?" << endl;
cin >> inputName

if(inputName>= 20 char) cout << "Your REAL name, please." << endl;

else

cout << Thats a very funny name, << inputName << ". Very funny..." << endl;

NOTE: Thats not all I have. I got the headers, declarations and other stuff too.

So now I need to have the bot say different things. So I'll have 4 other possible sayings, and the bot will randomly choose to say them with the input.

Need help on that.

For what you are describing I think you'd probably be better off setting up an array of strings, then randomly select a response from the array. This way you could have an array of questions, array of statements, array of jokes etc.

If however you would like to randomly select functions, you can setup an array of pointers to functions then randomly select them. Here's an example....

Code:

#include <iostream>
#include <ctime>
using namespace std;

void function1();
void function2();
void function3();

int main()
{
    int randFunc;
    void ( *func[3] )() = { function1, function2, function3 };
    
    srand ( time(NULL) );
    randFunc = rand() % 3;
    
    ( *func[randFunc] )();
    
    cin.get();
    
    return 0;
}

void function1()
{
    cout << "Function 1 executed." << endl;
}

void function2()
{
    cout << "Function 2 executed." << endl;
}

void function3()
{
    cout << "Function 3 executed." << endl;
}
