Short C++ tutorial ( very short )

[Mystic Ravenous]

Ok this is a very short tutorials on C++, even though i'm only into Arrays right now, I feel I can share my knowledge a tad.


Ok, We will learn how to use a "function" to output text to the monitor.
It can also output

intergers " int " ( -1, -2, -3, -- 1, 2, 3).

float "float" (decimal numbers. 1.0, 2.0, 3.0)

characters "char" ( a, b, c, d, e, f "you call this string too")
and
Doubles " double " These are Floats but with more space.

The stuff in the " " is how you word declare varibales.

Ok, so you want to know how to declare a variable.
varibale, basically a way of allocating memory.

#include <iostream.h> //this is a comment
// ^ don't worry about this yet.

int main() // don't worry about this yet, just studying output.
{ // this tells the complier where the program begins.
char a=A; // declaring the varibale and giveing it a value of A
// always end a statement with a sei-colon ";"

int b = 1; /*declaring the variable b and assigning 1 as it's variable*/

/* This is another form of comments, C style. */

float c = 3.5; // Declaring c and assigning the value of 3.5 to it.

double d=3.1452698 /* declaring the variable d and assigning the value of 3.1452698 to it*/

cout << a << endl; //outputs the value of a to the screen
cout << b << endl; //outputs the value of b to the screen
cout << c << endl; // output the value of c ot he screen
cout << d << endl; //outputs the value of d to the screen

return 0; // terminates the program
} //closing brace


Ok since that looks crowded i'll type the program out without comments. so it looks better

#include <iostream.h>
int main()
{
char a =A;
int b = 1;
float c = 3.5;
double d = 3.1452698;

cout << a << endl;
cout << b << endl;
cout << c << endl;
cout << d<< endl;

return 0;
}


You can have as many whitespaces as you want in C++ ( whitespaces = spaces )

Anyone can add on tot his tutorial. If you want me to add on, reply to this. thanks alot.

Just a little note is case a newbie does not know what // means.
// has no affect on the program. A programmer makes a // and a statement following it. The statement is information on what the programmer is doing (or trying to do) It is like ummm.. a reminder. AN Example: "if a programmer looks at an old programm he wrote he can look at the // and see what he was doing.

//just a note

Good post dude...keep it up! People like yourself help educate those that don't know or need a bit of a push.

Ok, since you should have a basic understanding of Outpu, and got bored with it by now. I will go over basic input.
Bare with me here, I'm busying learning this language and TCP/IP ( and learning more about linux )..


Ok
I gope you remember the comment "//" "/* .... */" . If not look back on them.



#include <iostream.h> // don't worry about this yet.

int main() // or this, lol
{ // opening brace

int a; // our variable that we shall use

cout << " Enter a number to be shown on the screen : \t";

/* the "\t" means TAB, just like "\n" means new line */

cin >> a; // this ask for input by you, to set the value of a

/* notic the differenc between the cout "<<" and the cin ">>", << directs the message to output, and >> recieves the input by you. If i'm wrong onthis please correct me. But it isn't that important as long as you keep them right, and not mix them up */

cout << a << endl; // outputs the value of a

return 0;
} // end of program


remember to end all statements with a semi-colon " ; "


Now I will write the code out with no comments.

#include <iostream.h>

int main()
{
int a;
cout << "Enter a number to be shown on the screen : \t";
cin >> a;
cout << a << endl;

return 0;
}


ok well maybe this will help you all. I must go back to my learning now. If you all would still like some more tutorials, reply.

And remmeber, anyone can add on to this.

Later

Thanks, feels.

They can also go to gametutorials.com
if they feel the need to learn more, before I can write another tutorial. It is code heavily commented. If yall' want some links to e-books reply.



Later, cheers.
