What is the summary of c plus plus and sql in a programming language?

Answer 1

Your question is unclear. C++ IS a programming language. SQL is not (it is a specialized language for defining relational databases, inserting/retrieving/modifying data and specifying user access.)

Answer 2

PHP is primarily a web-development language to allow a server to modify a file based on a wide variety of possible input variables before sending it to the client. While PHP can be used for desktop applications, this is uncommon.

On the other hand, C++ is most commonly used for desktop applications, console games, language compilers and interpreters (such as PHP itself), and network components like the server that PHP runs on and the client it is responding to. Like PHP, C++ can modify pages requested by the client before sending them, but as it was not designed for this it requires much more complex code.

The syntaxes of the two are fairly similar from a line-by-line perspective because PHP was influenced by C and C++ among other languages, but the file structures are entirely different from each other. As a scripting language, PHP does not require that program logic be contained by functions, and an external source file can be included more than once without generating an error (second and subsequent includes are simply ignored). PHP cannot operate on pointer values, which prevents memory corruption errors but also removes some of the power of C++. C++ class syntax is much different from PHP's, with methods being defined outside the class.

Answer 3

In c module (%) operator can not be implemented on floating point numbers but in SQL % operator can be applied on floating point number and it returns a decimal point.
