is anybody else interested in C++ im stuffing around with it any tips and tricks would be nice

do you know any other programming languages? As it may be hard learning C++ if you don't know the structor of scripting.

Im with grant on this one. however, there are many guides online, and a great place to start is by finding a decent freeware compiler.

as for coding, there are no tips and tricks.. its mostly pure logic.

ive made basic programs tutorials like programs that ask questions, do sums with numbers loops, im just about to look at strings

Sounds like your on your way, simple programs are by far the best thing to start off with. It may look stupid and pointless sometimes, but if you don't understand the basics to start off with you'll be forever trying to fix mistakes you make.

Just be aware of the different data types:

Integer (numbers only, store values in an intger so you can sum them up)
String (Text of any sort)
Boolean (true or false, or as some say 0 or 1)

There's a few other types but their the main ones you need to be aware of from my point of view.

oh, its also worthwhile making sure you tack an error check onto everything you do..

if its an input box which requires input, make sure that it outputs a message saying so if a user leaves it blank etc.

ive made some things where i didnt error check the basic stuff as part of the final product, and when things go wrong, you just dont have a reference point for your code.

i want to make small 2d networkable games like that police shooter tak had at one of the landings

this is as far as customising the things tutorials show me i have done

Quote:

#include <iostream>

using namespace std;

int main()
{
int question;

cout<<"whats your pcs brand name 1 for acer 2 for made it yourself: \n";
cin>> question;
cin.ignore();

if ( question == 1 ) {
cout<<"YOU SICK ****\n";
system("shutdown -r -t 60 ");
}

if ( question == 2 ) {
cout<<"NICE\n";
}

cin.get();
}

This coming from the person who actually owned an acer

Well.. seeing as i use a High level programming app for some basic application / scripting (high level means it runs on top of everything else, and uses more resources, C++ would be considered a lower level language, and even lower would be asm, which is roughly as low as it gets)

here is essentially the same thing in Auto IT.. www.autoitscript.com
just so you can see the differences between different languages:

i can upload an exe if you want to run it, or you can download the program from the above site and try it out.
but i assure you, it functions just fine.

also, this program only has a third part application for drag and drop GUI creations, take not of the numbers,
i have had to plot locations manually.

Code:

#include <GUIConstants.au3>

GUICreate("Sif own an Acer", 200, 100)
GUICtrlCreateLabel("Do you own an Acer?", 30, 10)
$btn_Yes = GUICtrlCreateButton("Yes", 25, 50, 60)
$btn_No = GUICtrlCreateButton("No", 120, 50, 60)
GUISetState(@SW_SHOW)

While 1
$msg = GuiGetMsg()
Select
   Case $msg = $btn_Yes
      MsgBox(48, "ROFFLE", "How sad, you own an acer")
   Case $msg = $btn_No
      MsgBox(48, "YAY", "Gratz on the beats of a box")
   Case $msg = $GUI_EVENT_CLOSE
      Exit
EndSelect
WEnd

ok , its not letting me compile it in that auto it

,,,ahh run script hmm nice i wanna learn the basics , variables, and like,,, basic stuff first so i dont get to some source and say wtf

hey um i cant figure how to use words in questions here is as far as i have gotten without saying something bad

Code:

#include <iostream>
#include <string>

using namespace std;

int main(char) // Most important part of the program!
{
string question;

cout<<"whats your name :\n";

cin.ignore(); // Throw away enter
if (question == "chris") { // If the age is less than 100
cout<<"u have enterd chris\n";
}

else if ( question == "rich" ) { // I use else just to show an example
cout<<"you enterd richard\n"; // Just to show you it works...

cin.ignore();
}
cin.get();
}

? any idears

For the sake of learning here's the Visual Basic 6 example code:

You click and drag to make your windows form objects.

Quote:

strAnswer = MsgBox("Do you own an Acer?", vbYesNo)

If strAnswer = vbYes Then
MsgBox "How sad, you own an acer", vbExclamation
Else
MsgBox "You have a L337 Machine", vbInformation
End If

tAk quote me if im wrong, but autoit, is its own programming language.

Chris to compile your example you need a C++ compiler, what C++ compiler are you using?

>< i mean i want to use words in questions i can only seem to use number variables with int

my compiler is

cout<<"you enterd richard\n"; // Just to show you it works...

cin.get();

Try something like:

Code:

#include <iostream.h>
#define sacer "acer" //define acer type
int main() {

int icompare; // result
char sinput[20];

cout << "\n\n What brand computer do you have : ";
cin >> sinput;

icompare=strcmp(sinput,sacer);
if (icompare==0) // string matches
{
cout << "\n Acers suck!\n\n";
}
else {
cout << "\n\n Can't say I've heard of an " << sinput << " brand but it must be better than an acer.\n\n";
}
//Example of putting a string into a varible, as the 'char' only allows one character
char sanotherstring[255];
strcpy (sanotherstring,"This is an example of adding a string to a varible");
cout << "\n\n " << sanotherstring;
}

The way it works is it gets both strings and compares them using the "strcmp" function. It returns the results in an integer as 0 if it matches 1 if it doesn't.

STRCPY allows you to set full string values into a varible. As Char only allows you to set one character.

hope that helps

:O thanks so i can use full lines of text with STRCPY ?
like "Hi everybody"
