How To Create Table In Dev C%2b%2b

The first column in the table will be labeled (index). If data is an array, then its values will be the array indices. If data is an object, then its values will be the property names. Note that (in Firefox) console.table is limited to displaying 1000 rows (first row is the labeled index). The most interesting thing in this code is that this contains an operator which can retrieve any type of data from table. The definition is written. Here just pass the index and will return the data at a particular index.

In this article we will discuss how to create threads in C++11 using std::thread.

Introduction to C++11 Thread Library

Original C++ Standard supported only single thread programming. The new C++ Standard (referred to as C++11 or C++0x) was published in 2011. In C++11 a new thread library is introduced.

Compilers Required:
Linux: gcc 4.8.1 (Complete Concurrency support)
Windows: Visual Studio 2012 and MingW

How to compile on Linux: g++ –std=c++11 sample.cpp -lpthread

Thread Creation in C++11

In every C++ application there is one default main thread i.e. main() function. In C++ 11 we can create additional threads by creating objects of std::thread class.
Each of the std::thread object can be associated with a thread.

Header Required :

What std::thread accepts in constructor ?

We can attach a callback with the std::thread object, that will be executed when this new thread starts. These callbacks can be,

1.) Function Pointer
2.) Function Objects
3.) Lambda functions

Thread objects can be created like this,
New Thread will start just after the creation of new object and will execute the passed callback in parallel to thread that has started it.
Moreover, any thread can wait for another to exit by calling join() function on that thread’s object.

Lets look at an example where main thread will create a separate thread. After creating this new thread, main thread will print some data on console and then wait for newly created thread to exit.

Lets implement above using three different callback mechanism,

Creating a thread using Function Pointer

Creating a thread using Function Objects

Creating a thread using Lambda functions

Differentiating between threads

How To Create Table In Excel

Each of the std::thread object has an associated ID and we can fetch using,

Member function, gives id of associated thread object i.e.
To get the identifier for the current thread use,
If std::thread object does not have an associated thread then get_id() will return a default constructed std::thread::id object i.e. not any thread.

std::thread::id is a Object, it can be compared and printed on console too. Let’s look at an example,

im given an very tuff assignment like this
a. Introduction
we have read all input from q sql file.the name of sql file should be read by a command line.please any body help me to do? i tried some.
support of SQL of your ADT table to CREATE TABLE,
DROP TABLE and DELETE statements. Assume that your program can support only one table at
any time.
To enable efficient processing of DELETE statements, use pointer-based linked list as your
primary storage of data in the table. This avoids shifting of other tuples when a set of tuples is
deleted.
b. CREATE TABLE Statement
The CREATE TABLE statement should support the creation of one relational table of any
table name, and with a schema of up to six attributes of any data type of either STRING( n ) or
NUMBER. STRING (n) means a character string with a maximum of n characters, where n is a
value between 1 to 40. NUMBER means a number from -999999.99 to 999999.99.
Hint: Use data dictionary to record attribute names and attribute data types and refer to it when
processing SQL statements. This provides a higher abstract level of processing from native data
types provided by C++.
An Example of a CREATE TABLE statement is shown below

Assume that the first attribute is always the primary key and must be unique and not contain a
NULL value.
Your program should display
TABLE staff created.
after processing the statement.
c. DROP TABLE Statement
The DROP TABLE statement should drop a table from data dictionary and clean up
memory used the table.
An Example of a DROP TABLE statement is shown below.
DROP TABLE staff;
Your program should display
TABLE staff dropped.
after processing the statement.
d. DELETE Statement
The DELETE statement to support consists of two lines as shown below.
DELETE FROM staff
WHERE sno = “A1234”;
The features to support in WHERE clause is similar to the WHERE clause of a SELECT statement.
There is always only one condition which uses the = operator.
Your program should display the number of tuples deleted, such as,
5 tuples deleted.
after processing the statement.

my codings.

i did it in a normal way .please any body guide me 2 do in tht way i mentioned before.

How To Create Table In Dev C++ Version

The requirement for CREATE TABLE indicates that the table contents should be read from a text file (aka schema), not hard-coded in your program.

One common way to do that is to create a structure that contains the information for each field in the table

Now when the program reads the schema file it should build a linked list or c++ vector of the above structures for each field.
