Thread: First Program using 5 Different Tutorials on Cprogramming.com

Ok hello C++ gurus Im here to learn C++ and cprogramming is really helping me with the basics. Once I feel comfortable maybe I can pick up a book or two on C++. My main reason for learning C++ is for clienthooking for games. Finding the offsets and reversing the functions so u can hook to the client and do anything u want, such as drawing text, and rendering the playermodels or creating a aimbot so the crosshair automatically locks on to the enemy

Tutorials Used: [Thank you Cprogramming.com maybe I should make a C++ Blog hmmm.]

Code:

Intro to C++ The basics of C+
Loops in C++
Functions Functions...all about them, making and using the critters
Strings About character arrays

Source Code:

Code:

#include "stdafx.h"
#include <iostream> // preprocessor file so we can use functions from iostream
 

using namespace std; //this tells the compiler to use a group of functions that are apart of the library std. enables us to use functions such as cout and cin.
void getplayers(); // define the function............we have it.
int player; // a int which will hold how many players are on the server
int main() //the main function where the program starts at.
{
	
	char serverip[16]; // a string that will hold 16 characters.. A IP address can be no longer than 16 chars ex. 111.111.111.111 so we dont need anymore
	
	cout<<"Enter the IP im connecting to:"; // used to output text.
	cin>> serverip; // read a value into serverip etc the IP
	cin.ignore(); // function that reads and discards a character. 
	cout<<"Connecting to "<< serverip <<"\n";
cin.get(); //runs in input and expects the user to hit the return key. 
cout<<"Finding Players..";
cout<<"\n";  //clear a new line \n is not working on the outcall so lets just make a clear line so the last line is not caught up with the display of players.. cheap fix I guess but it works.

getplayers(); //time to call in the function
}


void getplayers() // a simple function

{


	for (int x = 0;x < 10; x++) // a simple loop, lets loop intill we find all the players on the server.
	{
		cout<<"Player "<< x <<endl; //output the player and his ID ex. Player 1
		player++;  //since this is going to loop intill int x is equal to 10 lets just add it.
	

}

	cin.get();
cout<<"There are " << player <<" players on this server.";
	cin.ignore();

}

Instead of

Code:

cout<<"\n";  //clear a new line

I would suggest

Code:

cout<< endl ;  //clear a new line 
or 
cout<< '\n';  //clear a new line

but the endl (when written in caps, ENDL), would be better.

And at some point, you'll need to create some variables.

I suppose it will be a very long way from here to online games.

Code:

	char serverip[16]; // a string that will hold 16 characters.. 
        //A IP address can be no longer than 16 chars ex. 111.111.111.111 so we dont need anymore
	
	cout<<"Enter the IP im connecting to:"; // used to output text.
	cin>> serverip; // read a value into serverip etc the IP

The comment and the code don't agree. cin will happily attempt to read any number of characters that the user chooses to input.

Yes, he is, and no, of course that doesn't work.

cin reads as much as you input. cin.getline() or cin.get() with the right arguments will do what you want, though.

then you're going to get a lot more than 16 characters stored ... somewhere, hopefully not on top of something you want to keep.

Yeah your right it doesnt cap it. So why does it only read one if its defined char serverip; because that defines 1 character and if i want 16 than use char serverip[16];

EDIT maybe it was only C outing one on the screen then?

i got it thanks Ice I was using the wrong args. but my idea was correct thanks I will look at it later I see what u mean now cin>> will return any input but with the right args using cin.get(args) I can make it read only read 16 characters even though its really unnecessary It will give me a better understanding of how it works thanks guys for all your post btw linked list scary me right now :| confusing..
