Hello, I'm making a text based game with C++, and my book never covered strings, (not where I am) and I am trying to do a simple program that gets a name from a user, and it prints it back out:

(Toggle Plain Text)

#include <iostream>
int main(){
 while (1 == 1) {
       
      string name;
       
cout << "WELCOME TO MAGE WARS v1.0! \n" ;

cout << "Hello there! What's your name?: \n";
getline (cin, name);
cout << "Welcome,";
cout string;
cout << ", to Mage Wars! We are in a world of need, and we are hoping a true"; 
cout << "hero like you would help us! Please! Destroy the evil mages!";

By the way: the error points out towards "cout string;"
Thanks!

replace

(Toggle Plain Text)

cout << string;

with

(Toggle Plain Text)

cout << name;

Name refers to the variable name, "string" refers to the type of the variable.

Nevermind, I got it working. Thanks so much man! I might be putting some more questions up in this thread.. hopefully that isn't a hassle for you all!

Okay, can anyone tell me how to print an int that creates a random number from 10-20 or something like that?
Kinda like a random number generator...
Thanks!

Unless you have a really non-compliant compiler you need to either put some scope resolution on cout (std::cout) or add a "using" directive. As a newbie, I will tell you that you need to test your input (cin) for success. If you aren't a newbie, then your code is just schlocky. I have no way to decide, at this point.

You might elucidate on the things you implemented to fix it. The forum is for the benefit of others who might have similar questions. It won't kill you to contribute, as opposed to just saying, "Oh, geez, Mom, I fixed it!!!".

As for your second question, check the documentation for "rand" and apply some rudimentary math skills.

Thank you, I will check it out.

	cout << "kill";

	} else if(option == 3){

	}


	} else {

	}
	cout << yourdmg << "you been attacked";

	} else if(option == 2){

		cout << "buy";

	} else if(option == 3){

		cout << "stats";

	}
	} else {

		cout << "Wrong reply!";
		

}
	
system("PAUSE");

}

ACtually, I forgot the main include iostream... i'm full of mistakes..

Hope that helps.

Thanks Prm!
Okay, last question, pretty simple.
How do I slow the time of when cout starts? Like I want 10 seconds before one cout is actually processed.. anyway?

You need to use some kind of a delay. There is no sleep() function in standard C++, but you can roll your own. Simply store the current time in a time_t variable, then loop until the current time is x seconds greater. This should work:

(Toggle Plain Text)

void sleep(int delay)
{
  time_t start = time(NULL);
  double delay_double = delay;  // do the conversion once, rather than each iteration of the loop
  while(difftime(time(NULL), start) < delay_double)
    ;
}

The downside to this approach is that it, like any tight waiting loop, is needlessly demanding on the CPU. You should see if your OS supports some kind of sleep() function. Generally, such a function will put the thread to sleep for the requested duration, rather than consume CPU cycles while it's idling.
