Can any one teach me C++?

[Luke]

Can anyone, 'Cause the internet doesn't have much in the way which I've learnt. I've learnt the printf and scanf but on the internet it doesn't teach you that...

Here is the C++ Language Tutorial: www.cplusplus.com/doc/tutorial/

Hope this will help you.

Doesn't teach you what exactly? When it comes to C++ and its standard libraries I promise you it's covered and explained somewhere, you just need to take a few minutes to look through Google to find it.

Besides Debrah's link there's a list of resources listed in the Useful Links thread.

CProgramming.com and CPlusPlus.com being the two sites I'd recommend most.

C++ is quite complex, and some actually take classes. Where I live, it shouldn't be a problem finding a place that holds these classes. Of course, age can be a issue. Well, you can learn online, but beware it's complex.

I'm taking my second course in C++ at university and I can tell you that there's quite a lot to learn, but if you spend a lot of time reading and experimenting you can get it. Make sure you get a firm understanding of pointers because they are extremely important. I recommend buying a book if you want to get serious about learning the language because that's what I did before I went to university and it gave me a huge head start. Feel free to send me a private message if you need help with something.

I have been given three books by my parents friend who is a master at it. It's in advanced though. I can make a basic calculator but I want to do more. Every Wednesday I get lessons, they started last week, and we get entered into a comp wither we like it or not and thats coming up soon so I'm wanting to learn in between the lessons but the tutorials on the internet are teaching me a differnet way to what my teacher is telling me. After learning printf and scanf what would I go onto next? If statments maybe??

Thanks to the others for the links and comments
Debrah, thats currently what I'm trying to use to teach myself It's a good website

Get all the basics down such as if statements, mathematical expressions, loops, functions, arrays, and knowing how to use cout and cin. I'm not listing them all, but just follow some tutorials and they should cover it all. Once you feel compfortable with the basics, try to make a simple game such as a text based RPG or Hangman. If you make an RPG, just have a function that prints a numbered menu such as the one below and then do something for each option.

1. Leave your swamp.
2. Fight some knights.
3. Rescue the princess.
4. Marry her.
5. Exit

Enter a number:

Another easy game that will help you get used to programming is "Guess the number". Just generate a random number, and then every time the user enters their guess tell them "too high" or "too low" until they figure out the number.

Just be sure to play around with loops and if statements for a bit before you do a game.

Thanks, I'll work on that tonight and then post back what I end up with

[Jordan]

No problem, and good luck. Let me know if you need help.

[Luke]

Thanks Jordan

This is what I've done so far and it works



#include <cstdio>

int menu, num1, num2,total;

int main(){
printf("Enter two numbers:\n");
scanf("%d",&num1);
scanf("%d",&num2);
printf("Please choose an option\n1. Add\n2. Subtract\n3. Multiply\n4. Divide\n");
scanf("%d", &menu);

if(menu==1){
total=num1+num2;
printf("Total=\n%d",total);
}

if(menu==2){
total=num1-num2;
printf("Total=\n%d",total);
}

if(menu==3){
total=num1*num2;
printf("Total=\n%d",total);
}

if(menu==4){
total=num1/num2;
printf("Total=\n%d",total);
}

if(menu>4){
printf("Please Try Again And Enter A Number Between 1 And 4!!!\n");
}

return 0;

}



I'm going to try loops hopefully now!

I could have sworn that c++ uses cout ... not printf ...

Hmm ... could just be me ... looks more like C that does! :/

Aww well ... yea, I'm in the process (term used very loosely) of teaching myself C++...

[Jordan]

Yeah, you should use cin and cout instead. It's safer and makes things a lot easier because it has overloaded insertion and extraction operators (<< & >>) so it will automatically detect if the content is an integer, string, char etc.

cout << "Enter two number:" << endl;
cin >> num1 >> num2;
cout << "Please choose an option\n1. Add\n2. Subtract\n3. Multiply\n4. Divide\n";
cin >> menu;

[Luke]

Yeah the person who taught me seems to do it that way :/ Umm can you give me an eg of a loop?

[progon]

In all fairness, you're asking for us to hold your hand, I feel....

Loops are easy, you can do them using for(), while(), etc.
