zonets first program :)

[Zonet]

Here is my first program, just readed 5 minutes ;(

#include <iostream>
using namespace std;

int main()
{
int length, width;
length = 10;
width = 8;
	cout << "The length is " << length "\n ";
	cout << "The width is " << width "\n ";
	cout << "The area is " << length * width;
return 0;
}

Is right ?

 

[chojrak]

Keep learning.

Read this:
cin - C++ Reference

And make something like:

Please type width:
User: 5
Please type height:
User: 10
The area is: 5*10 = 50

Thanks Sality, I've read book .pdf.
I'm also going to buy a book as Kiper recommended

Edit: Would be something like this or, tell me if any errors

#include <iostream>
using namespace std;

int main()
{
int length, width;
	cout << "Type a length: \n";
	cin >> length;
	cout << "Okay, the length is: " << length;


	cout << "Type a width: \n";
	cin >> width;
	cout << "Okay, the width is:" << width;

	cout << "So, the area will be:" << length * width;
return 0;
}

well done A+

}

Well done

@Edit:
Another task 4 you

Read this:
http://www.cplusplus.com/reference/clibrary/cstdlib/rand/

And do something like:

Save random number to variable.
Please type number:
User: XXX
if (xxx == variable)
user won the match!

 

[Paxton]

#include <iostream>
using namespace std;

int main()
{
    while(true){
int length, width;
	cout << "Type a length:";
	cin >> length;
	cout << "\nOkay, the length is: " << length << "\n";


	cout << "\nType a width:";
	cin >> width;
	cout << "\nOkay, the width is:" << width << "\n";

	cout << "\nSo, the area will be:" << length * width << "\n";
}

}

A bit bit better.

}

A bit bit better.

Definig variables each loop? Suxor
Also add screen clearing.

Scanf("")
printf("")
Isn't that C? I know its same.. But it's C?

 

[chojrak]

Ah, fuck! There's an example XD
It's c++, but same functions, i guess.

I'll try do it in another way if there is example
But I still doesn't understand about that headers.. like

#include <iostream>

 

[chojrak]

It mean something like load library called iostream.

Hmmm for example you can load windows library by: #include <windows.h> and you have new functions.
windows.h - Wikipedia, the free encyclopedia

Example function of windows lib:
http://msdn.microsoft.com/en-us/library/ms645505(VS.85).aspx

Example usage:

MessageBox(NULL, "I'm pr0!", "Pro Window", MB_OK | MB_ICONINFORMATION);

 

[Colandus]

iostream is the library for input/output reading. input/outputstream

Input means when someone write something / click or whatever while output is when you show something to them

Input: cin
Output: cout

Whereas "c" stands for "console"

So, cin = "console input" and cout = "console output"

Yaya!

Sality: Thanks for trying to help me When I buy a book, I'll learn everything about that :9 But still gonna try to udnerstand it before. It'll just be easier for me
As Sality said, but can't make with random numbers xD!

#include <iostream>
using namespace std;

int main()
{
int lessA, answer;
answer = 7;
       cout << "Type a number between 1-10\n";
       cin >> lessA;
           if(lessA == answer) {
                    cout << "Congratulations! You won.\n";
                    }
           if(lessA > answer) {
                    cout << "Wrong answer. The number is lower.\n";
                    cin >> lessA;                       
                             }
           if(lessA < answer) {
                    cout << "Wrong answer. The number is higher.\n";
                    cin >> lessA;                           
                              }
           system("PAUSE");
return 0;
           
}

 

[chojrak]

As I said, keep learning.

Little bit edited version:

#include <iostream>
using namespace std;

int main()
{
	int lessA, answer, tries;
	answer = 7;
	tries = 2;

	while (tries > 0)
	{
		cout << "You have " << tries << " tries left.";
		cout << "Type a number between 1-10\n";
		cin >> lessA;
		if (lessA == answer)
		{
			cout << "Congratulations! You won.\n";
			tries = 0;
		}
		else if (lessA > answer)
		{
			cout << "Wrong answer. The number is lower.";
			tries--;
		}
		else if (lessA < answer)
		{
			cout << "Wrong answer. The number is higher.";
			tries--;
		}
		system("cls");
	}
	cout << "Thanks for playing :)\n";
	system("PAUSE");
	return EXIT_SUCCESS;
}

I got a book called "C++ Programmering" Its very detailed.
I dont know realy if its a english texted version but i nearly can promise that
A book i recommend for people that are interested
