Intro C++ For Newbie :)

Speaking of C and C + + as the language of its predecessor, C is included language pemrograma n intermediate level.
Creator of C is Brian W. Kernighan and Dennis M. Ritchie in 1972. C is a programming language structured program divides into a number of blocks(sub-program). The aim is to facilitate the making and program development. Programs written
with C easily moved from one type of machine to another. it is due to the standardization of C is ANSI (American National Standards Institute) the reference compiler makers C.

C + + was created a decade after C. C + + was created by Bjarne Stroustroup
from Bell Laboratories, AT & T in 1983. Initially C + + named
"A better C". Name of C + + itself named by Rick Mascitti. The sign + +
derived from the increment operator in C language

,so for new lest try this u can do by part in part,and this is part one :

A. Hello World
Here is a sample C + + program that is simple
# include <iostream>
void main ()
{
cout << "Hello world. \ n";
}
Once compiled and dirun, the result is visible on the display Hello World.


B. Function main ()
Program C + + it will never be separated from the function / function. it is because it is a characteristic of OOP. A C + + program has at least one function the main (). This function is the beginning of the main program. Posts in main ()
is the name of the function, whereas part enclosed by {and} are called block (body function). In this case, an early sign of a block {and} are marks the end of the block. As in Pascal, the Pascal {identical to BEGIN, whereas identical} END. The command void means that the function main () does not return a value / value. How to write a function main () is not absolute as above. Here's how another writing

# include <iostream>
int main ()
{
cout << "Hello world. \ n";
return 0;
}


C. Statement
Command cout << "Hello world. \ N"; is one example
statement. Command is used to print the writing on the screen. Each statement must end with;
It is important to note here that the C + + program is
Case Sensitive, meaning uppercase and lowercase letters are considered different. Signs \ n is used to move the line.

D. file Header
In the example above, called iostream.h header file. The header file necessary for court orders can be executed. If the header file removed, there will be an error. To access the header file, use command # include <file header>, or # include "file header". In one program may involve more than one header file. Note:

Command cout << "Hello world. \ N";
can be replaced with printf ("Hello world. \ n");
However, to be able to use printf required header file stdio.h
E. Removing Screen
In C + +, the command clrscr (); used to remove / clean up
display. This command will be executed after adding the header file conio.h
# include <iostream>
# include <conio.h>
void main ()
{
clrscr ();
cout << "Hello world. \ n";
}


F. comment
You can add comments to your program. Here's the style for
add comments.
/ / ----------------------------------
/ / This is the first remarked
/ / ----------------------------------
or
/ * ----------------------------------
I remarked that this was the first
---------------------------------- * /

this is part one i will upgarde part two in page 2 or 3 later :)

well like i said before i will cont this turor,and some trick for newbie,lest see my part 2 guys . . .

STRINGS

In programming, a string is a collection of some karakterkarakter. To distinguish the character string in C + + is distinguished writing. A value is a string enclosed in quotation marks if double "...", eg "I". While the character (char) flanked by signs single quotes, eg 's'.

So what about the "s"?? In this case "s" is also a string, although the characters look just one constituent. But in fact, the "s" was drawn not only the character 's' only, but there are also NULL character or '\ 0', which serves as a sign of the end of the string.
To declare a variable is a string, then the command: char variables [max character];

example:
char text [20];
The above command means that the text is a string variable with the number of
maximum characters that can be stored is 20 (including the character
NULL).

A. Initialization String
Suppose a string variable say a sentence [30] will be rated "MY
Learning C + + ", then the command:
char sentence [30] = "MY LEARNING C + +";
Program details as follows:
# Include <iostream>
# Include <conio.h>
void main ()
{
int a;
a = 20;
char sentence [30] = "MY LEARNING C + +";
cout << "value a =" << a << endl;
cout << "Value sentence =" << sentence << endl;
}

It should not be like this!
void main ()
{
int a;
char sentence [30];
a = 20;
sentence = "I'M LEARNING C + +" / / or
sentence [30] = "MY LEARNING C + +";
cout << "value a =" << a << endl;
cout << "Value sentence =" << sentence << endl;
}

C. Reading String from Keyboard
Furthermore, how to read a string from the keyboard?
Here's an example:
# Include <iostream>
# Include <conio.h>
void main ()
{
char name [20];
char address [30];
cout << "Enter your name:";
cin.getline (name, sizeof (name));
cout << "Enter your address:";
cin.getline (address, sizeof (address));
cout << "Your Name:" << name << endl;
cout << "Address is:" << address << endl;
}

D. Copying a String

Then how to mengassign a string from a variable to a variable
Another? For example, given a string kata1 "HALLO". Furthermore word2 will be given string
of kata1. To do this, you can not give orders
word2 = word1;
The command used for the above purposes are to:
strcpy (word2, word1) / / copy the contents of word1 to word2

Example:
# Include <iostream>
# Include <conio.h>
# Include <string.h>
void main ()
{
kata1 char [20] = "HALLO";
kata2 char [20];
strcpy (word2, word1);
cout << "word1:" << endl << word1;
cout << ":" << endl << word2;
}
E. Function for String Operations
Function-The following function can be used to manipulate strings.
Before the function is used, add string.h header file to include.
- Knowing the length of the string with strlen ()
syntax:
strlen (string)
will mereturn integer specifies the length string.
Example:
int panjangteks;
char sentence [30] = "C + + LEARNING IS NOT DIFFICULT";
panjangteks = strlen (sentence);
cout << "Length of string:" << panjangteks;
- Combining strings with strcat ()
Syntax:
strcat (string1, string2)
add string2 to string1.
Example:
kata1 char [5] = "ONE";
kata2 char [5] = "TWO";
strcat (word1, word2) / / value word1 be "ONE TWO"

- Convert to uppercase with strupr ()
Syntax:
strupr (string)
Changing small letters of the string to uppercase.
Example;
char string1 [30] = "aBcDefgHIJKLmno";
strupr (string1) / / value of string1 to "ABCDEFGHIJKLMNO"
- Convert to lowercase with strlwr ()
Syntax:
strlwr (string)
Function is the opposite of strupr ().
- Finding Substring with strstr ()
Suppose given a string "New York City". Whether
string "METRO" contained in that string?
To determine this with C + +, we can use the function
strstr ().
Syntax:
strstr (string1, string2);
Function will be mereturn value of 1 if a substring of string2
string1, and will mereturn 0 otherwise.
Example:
if (strstr ("New York City", "Cool") == 1)
cout << "is a substring";
else cout << "Not a substring";
- Reverse a string with strrev ()
How to reverse a string "C + +" to be acquired "C + +"?
Here are the commands in C + +,
syntax:
strrev (string);

Example:
char word [10] = "C + +";
strrev (word);
cout << word;
