#include // of course you need the Include guys = )

that's really nice and all, but you're not including anything. It's just a #include without anything after it. I'm surprised whatever compiler you used doesn't scream at you.

And there's a logic bug in your program. It doesn't do anything if you enter 30.

Code:
#include <iostream.h>

int main()
{
int num;
cout<<"Please Guess the Number 1,2,3,4,5,6,7: ";
cin>>num;
if(num==1)
{
cout<<"Sorry Try Again";
}
else if(num==2)
{
cout<<"Sorry Try Again";
}
else if(num==3)
{
cout<<"Sorry Try Again";
}
else if(num==4)
{
cout<<"Sorry Try Again";
}
else if(num==5)
{
cout<<"Ding Ding That is The Correct Number";
}
else if(num==6)
{
cout<<"Sorry Try Again";
}
else if(num==7)
{
cout<<"Sorry Try Again";
}

int a;
cin >> a;
return 0;
}
Heres another one lol = )

whats the int a at the end for? and thats too many else if statements in my opinion. use a switch case instead. Then again, thats just about style.

tut on switch statements

oh, i just read your other program. Thats not how you stop it so you can see it, you are just wasting memory (not like its a lot but hey, its better you dont get used to it now that you are startin to learn).
#include "conio.h"
getch(); //that will pause till you press a key

You don't need all those else if's, either... just do:
if(num == 5)
{
cout<<"Ding Ding That is The Correct Number";
}
else
{
cout<"Sorry Try Again";
}

Thats because gcc is a c compiler where as g++ is a c++ compiler, i have used both, and they are the same except for that one thing.
At any rate, good luck with your programming, its fun, but not usually easy. I've spent the last 2 evens for like 6 hours a day working on my one program so, just be prepared to spend alot of time on it. Don't get discouraged, and ENJOY POINTERS! their your friend...

{Mr. Rage, I plan on showing up to irc tonight, if you could be there, i'd like to have you help me test my program to test requirements if you would please}

Regards,

Skull

don't understand exactly what your asking coleman, try rephrasing it. if you are trying to ask what the above program does, it i just a guessing game. the user enters a number and it tells the user if they got it right or wrong.

coleman, the program just tells u if you got it right or wrong, thats all...nothing more. even if u didnt know c++ u could go through the code and at least figure that part out

coleman, c++ is a programming language, that means it is used to create other programs. the program ice created has no practical use other than to learn how to program in c++. as for getting c++ go here http://www.borland.com/products/downloads/download_cbuilder.html# click to download the compiler. i believe it is free.

I think that you can use the key-words 'switch' instead of 'if-else'.

wouldn't including stdlib.h and using system("pause"); be a little less coding. You could even define it as something like:
Code:
#define PAUSE system("pause")
and then go to use it like this:
Code:
main()
{
PAUSE;
}
and it would come out like this:
"Press any key..."
or similar message

C++ is fun. I suggest you get this book:

http://www.amazon.com/exec/obidos/tg/det...ks&n=507846

Very good. very good stuff indeed.

That and read some online tutorials. Write some neat code, have some cool fun. Oh, pergesu has good stuff to (find his profile, he's got links in it) and uhm uhm uhm other than that check out http://www.allegro.cc when you want to do low-level graphics programming.

And learn java too.

Coleman, if you don't know what you'll be able to do by being able to program C/C++, it's likely that there isn't much point in you learning it. If you'd just like to play around on the web, I suggest learning the basics first. Start with XHTML and PHP.

It's a example.Perhaps this example teaches the reader the application of the key word"if... else if...else". I think so.

Coleman: get to Dev C++ It's good

Ice: use something like this.. {variable = rand() % max;}
It'll give you a random number between 0 & "max"(which should also be replaced). I don't really know much about how it works, since I don't actually program in C++ :-D

variable = rand() % max;

rand() produces a random integer value.
% is called the modulus operator. It's basically what you learned to be the remainder in division. Ie. 5 % 3 = 2 and 16 % 5 = 1
As for this function, it actually only returns a number from 0 to max - 1, as you can't divide a number by a number and have the remainder equal to the divisor. Ie. a % b cannot equal b.
