C++ Program "Bangun Datar" by Sebastian Mandai

hallo....
kawan - kawan blogger semua ...dan juga para pecinta dunia IT. Postingan saya sebelumnya membahas tentang Apa Itu Bahasa Pemograman C++???, bagi teman - teman sekalian jika hanya membaca dan tidak mempraktekannya maka rasanya kurang malahan kita jadi tidak paham dengan apa yang dipelajari.
jadi, aku sedikiti berbagi nih, contoh Program C++ :

#include "iostream.h"
#include "conio.h"
 void main ()
{
 clrscr ();
 cout << "   Bangun Datar "<< endl ;
 cout << "=================== " << endl << endl ;
 const float PHI = 3.14 ;
 const float S   = 0.5 ;
 int s, t, l, p, d1, d2, r, a ;
 int luas_1, kllg_1, luas_2, kllg_2;
 float  luas_3, kllg_3, luas_4, kllg_4, luas_5, kllg_5 ;

 s  = 4 ;                  // s adalah sisi
 t  = 6 ;                  // t adalah tinggi
 l  = 2 ;                  // l adalah lebar
 p  = 3 ;                  // p adalah pangjang
 d1 = 12 ;                 // d1 adalah diagonal pertama
 d2 = 6 ;                  // d2 adalah diagonal kedua
 r  = 7 ;                  // r adalah jari - jari
 a  = 4 ;                  // a adalah alas

 luas_1 = s * s ;          // luas persegi
 kllg_1 = 4 * s ;          // keliling persegi

 luas_2 = p * l ;            // luas persegi panjang
 kllg_2 = 2 * (p + l) ;      // keliling persegi panjang

 luas_3 = S * a * t ;    // Luas Segitiga
 kllg_3 = s + s + s ;    // Keliling segitiga

 luas_4 = S * d1 * d2 ;    // Luas layang-layang
 kllg_4 = s + s + s + s ;  // Keliling layang - layang

 luas_5 = PHI * r * r ;     // Luas Lingkaran
 kllg_5 = 2 * PHI * r ;     // Keliling Lingkaran

 
 cout << "            |Persegi| " << endl ;
 cout << "            --------- " << endl ;
 cout << "|Sisi     =          " << "4" << "      |" << endl ;

About Programming Language C + + by Sebastian Mandai

Waktu telah berlalu hingga sayapun tidak merasakannya dan akhirnya blog ini terasingkan alias tidak lagi dipedulikan, tetapi kali ini blog dengan nama mandaipc ini atau dengan alamat http://www.mandaipc.web.id  ini akan bangkit dengan informasi dari dunia IT yang selalu Up To Date.

Blog ini insyaallah akan menjadi besar...amin...

Yang diatas adalah sedikit statement yang akan membawa mandaipc bangkit, dan sekrang pada tulisan/postingan kali ini saya akan membahas tentan Bahasa Pemograman C++.

C++ adalah bahasa pemograman atau bisa dibilang C++ hanya keturunan dari bahasa pemograman C.
contoh sedikit dari bahasa pemograman C++ :

#include 
  void main ()
 {
  cout << "aku suka C++" << endl ;
 }

Command on The MYSQL by Sebastian Mandai

What is MySQL?
MySQL is one type of database server that is very famous for its popularity due to MySQL using SQL as the language basis to access the database. In addition, it is Open Source (you do not have to pay to access them) on various platforms (except for type enteprize, which is commercial).MySQL including the type of RDBMS (Relational Database Management System), which is why the term table, columns, and rows are used in MySQL. In MySQL, a database containing one or more columns and rows contain multiple columns, the term table, rows, and columns can be seen from the practice later ... ..!!!.

Preparation:- The first computer already exists mysql- Be careful.

1. Set the root password
The command to give the password is:
Mysqladmin-uroot password [name of the password]
Example:
Mysqladmin-password uroot mandai

2. Opening MySQL from dosOpen up the dos and typing this command:
Mysql-u root-p
And as it appears
Enter password:
Enter your password you provided.
3. Creating a database
how to create a database by typing the following command:
mysql> create database [database name];
For example:
mysql> create database smk_labor;

4. Enabling a database that was createdEnter this query command:
Mysql> use [database name]
Example:
Mysql> use smk_labor;Database changed
The word changed this database is a message that means that you have enabled database that you created.

5. How to view a list of tables
Typing the command beriku:
Mysql> show tables from mysql;
So this command will display a list of mysql table

6. How to create table to database
The syntax or command such as:
Mysql> create table [table name] ([Column a] [type] [width],[Column b] [type] [width],... ... ... ... ... .... ... ....,[Column n] [type] [width]);Remember a command that has been completed typed must end with a semicolon [;]Example:
Mysql> create table teacher (nip char (5) not null,name varchar (35) not null,gender enum ('p', 'w')religion varchar (15) not null,);Query ok, o rows affected (0:36 sec)
After that you can still see a series of tables that you can do:By typing the command
Mysql> desc teachers;
Then he will display a table of teachers along with the circuit.

7. Using alter command
Here is perintag ddI alter command used to perform a design change table to table with the new structure.
Type the following command:
Mysql> alter table [table name]Change [data yanga ingiin modified]Query ik, 0 rows affected (0.70 sec)
Example:
Mysql> alter table teacherChange expertise graduates varchar (1 -) not null;Query ik, 0 rows affected (0.70 sec)
So the field name will be changed to graduate skills.
8. Entering data into tablesType the following command:
Mysql> insert into [table name] ([column a, column b, column n]) values ​​([isi_kolom a, isi_kolom b, ... ..., isi_kolom n]);


Example:
Mysql> insert into teacher (nip, name, sex, religion)Values ​​('10023 ',' mind ',' male ',' Islam ');Query ik, 0 rows affected (0.70 sec)
9. Command to see tables
The following table meliha command
Mysql> SELECT * FROM [table name];
Example:
Mysql> select * from teachers
The purpose of this star symbol is a table showing all the contents from nip to graduate.
If you want to show both the name and religion only data type the following command:
Mysql> SELECT [column a, column b] from [table name];
Example:
Mysql> select name, religion from a teacher;


10. Delete the contents table
The following command syntax:
Mysql> delete from [table name] WHERE [column / content you want to delete]
Example:
Mysql> delete from teachers' WHERE field = 'name';Query ik, 0 rows affected (0.70 sec)


Thus the command - the command query that I know ... ..Hopefully you can do it themselves ...
