Database Connectivity using C/C SQL (Structured Query Language) is a fourth-generation language (4GL) that is used to define, manipulate, and control an RDBMS (relational database management system). I am quite new to C. I have a project to make in which I have to connect a C Program to a Microsoft Access Database. So this is what I have to do: Make the Access Database ( I can do this.) Connect the Database with C Forms Program ( This is what I need help in.) So I just want to know three things. MySQL C API programming tutorial. This is a C programming tutorial for the MySQL database. It covers the basics of MySQL programming with the C API. You may also consider to look at the MySQL tutorial on ZetCode.

In this chapter, you will learn how to use SQLite in C/C++ programs.Installation
Before you start using SQLite in our C/C++ programs, you need to make sure that you have SQLite library set up on the machine. You can check SQLite Installation chapter to understand the installation process.C/C++ Interface APIs
Following are important C/C++ SQLite interface routines, which can suffice your requirement to work with SQLite database from your C/C++ program. If you are looking for a more sophisticated application, then you can look into SQLite official documentation.Sr.No.API & Description1
sqlite3_open(const char *filename, sqlite3 **ppDb)
This routine opens a connection to an SQLite database file and returns a database connection object to be used by other SQLite routines.
If the filename argument is NULL or ’:memory:’, sqlite3_open() will create an in-memory database in RAM that lasts only for the duration of the session.
If the filename is not NULL, sqlite3_open() attempts to open the database file by using its value. If no file by that name exists, sqlite3_open() will open a new database file by that name.2
sqlite3_exec(sqlite3*, const char *sql, sqlite_callback, void *data, char **errmsg)
This routine provides a quick, easy way to execute SQL commands provided by sql argument which can consist of more than one SQL command.
Here, the first argument sqlite3 is an open database object, sqlite_callback is a call back for which data is the 1st argument and errmsg will be returned to capture any error raised by the routine.
SQLite3_exec() routine parses and executes every command given in the sql argument until it reaches the end of the string or encounters an error.3
sqlite3_close(sqlite3*)
This routine closes a database connection previously opened by a call to sqlite3_open(). All prepared statements associated with the connection should be finalized prior to closing the connection.
If any queries remain that have not been finalized, sqlite3_close() will return SQLITE_BUSY with the error message Unable to close due to unfinalized statements.Connect To Database
Following C code segment shows how to connect to an existing database. If the database does not exist, then it will be created and finally a database object will be returned.
Now, let’s compile and run the above program to create our database test.db in the current directory. You can change your path as per your requirement.
If you are going to use C++ source code, then you can compile your code as follows −
Here, we are linking our program with sqlite3 library to provide required functions to C program. This will create a database file test.db in your directory and you will have the following result.Create a Table
Following C code segment will be used to create a table in the previously created database −
When the above program is compiled and executed, it will create COMPANY table in your test.db and the final listing of the file will be as follows −INSERT Operation
Following C code segment shows how you can create records in COMPANY table created in the above example −
When the above program is compiled and executed, it will create the given records in COMPANY table and will display the following two lines −SELECT Operation
Before proceeding with actual example to fetch records, let us look at some detail about the callback function, which we are using in our examples. This callback provides a way to obtain results from SELECT statements. It has the following declaration −
If the above callback is provided in sqlite_exec() routine as the third argument, SQLite will call this callback function for each record processed in each SELECT statement executed within the SQL argument.
Following C code segment shows how you can fetch and display records from the COMPANY table created in the above example −
When the above program is compiled and executed, it will produce the following result.UPDATE Operation
Following C code segment shows how we can use UPDATE statement to update any record and then fetch and display updated records from the COMPANY table.
When the above program is compiled and executed, it will produce the following result.DELETE Operation
Following C code segment shows how you can use DELETE statement to delete any record and then fetch and display the remaining records from the COMPANY table.
When the above program is compiled and executed, it will produce the following result.

C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This C++ tutorial adopts a simple and practical approach to describe the concepts of C++ for beginners to advanded software engineers.Why to Learn C++
C++ is a MUST for students and working professionals to become a great Software Engineer. I will list down some of the key advantages of learning C++:
*
C++ is very close to hardware, so you get a chance to work at a low level which gives you lot of control in terms of memory management, better performance and finally a robust software development.
*
C++ programming gives you a clear understanding about Object Oriented Programming. You will understand low level implementation of polymorphism when you will implement virtual tables and virtual table pointers, or dynamic type identification.
*
C++ is one of the every green programming languages and loved by millions of software developers. If you are a great C++ programmer then you will never sit without work and more importantly you will get highly paid for your work.
*
C++ is the most widely used programming languages in application and system programming. So you can choose your area of interest of software development.
*
C++ really teaches you the difference between compiler, linker and loader, different data types, storage classes, variable types their scopes etc.
There are 1000s of good reasons to learn C++ Programming. But one thing for sure, to learn any programming language, not only C++, you just need to code, and code and finally code until you become expert.Hello World using C++
Just to give you a little excitement about C++ programming, I’m going to give you a small conventional C++ Hello World program, You can try it using Demo link
C++ is a super set of C programming with additional implementation of object-oriented concepts.
There are many C++ compilers available which you can use to compile and run above mentioned program:
*
Apple C++. Xcode
*
Bloodshed Dev-C++
*
Clang C++
*
Cygwin (GNU C++)
*
Mentor Graphics
*
MINGW - ’Minimalist GNU for Windows’
*
GNU CC source
*
IBM C++
*
Intel C++
*
Microsoft Visual C++
*
Oracle C++
*
HP C++
It is really impossible to give a complete list of all the available compilers. The C++ world is just too large and too much new is happening.Applications of C++ Programming
As mentioned before, C++ is one of the most widely used programming languages. It has it’s presence in almost every area of software development. I’m going to list few of them here:Dev C++ Programming App Download
*
Application Software Development - C++ programming has been used in developing almost all the major Operating Systems like Windows, Mac OSX and Linux. Apart from the operating systems, the core part of many browsers like Mozilla Firefox and Chrome have been written using C++. C++ also has been used in developing the most popular database system called MySQL.
*
Programming Languages Development - C++ has been used extensively in developing new programming languages like C#, Java, JavaScript, Perl, UNIX’s C Shell, PHP and Python, and Verilog etc.
*
Computation Programming - C++ is the best friends of scientists because of fast speed and computational efficiencies.
*
Games Development - C++ is extremely fast which allows programmers to do procedural programming for CPU intensive functions and provides greater control over hardware, because of which it has been widely used in development of gaming engines.
*
Embedded System - C++ is being heavily used in developing Medical and Engineering Applications like softwares for MRI machines, high-end CAD/CAM systems etc.
This list goes on, there are various areas where software developers are happily using C++ to provide great softwares. I highly recommend you to learn C++ and contribute great softwares to the community.Dev C++ Program ExamplesAudience
