Class 12 Notes Computer Science Fundamentals Of C Language Exercise – C++ is a general-purpose programming language designed as an extension of C to incorporate an object-oriented paradigm. It is a necessary and structured language.
C++ is an object-oriented programming language, as opposed to a procedural programming language. This is the most important feature of C++ language. It can create/delete objects while programming. It can also create drawings from which objects can be created. We have discussed the concept of object oriented programming in C++ in this article.

C++ executables are not platform independent (programs compiled on Linux do not run on Windows), but they are machine independent.

Let’s understand this feature of C++ with an example. Let’s say you wrote a piece of code that can run on Linux/Windows/Mac OSx, which makes it C++ machine independent, but the C++ executable cannot run on different operating systems.
It is a simple language in the sense that programs can be divided into logical units and sections, has rich library support, and has a wide variety of data types. Also, the C++ auto keyword makes life easier.
The idea behind Auto was to allow the C++ compiler to calculate the data type at compile time instead of declaring the data type each time. Note that you cannot post something without an initiator. There should be a way for the compiler to calculate your type.
C++ is more of a high-level language than a mid-level programming language. This makes it easier to work with C++ because it is a high-level language because it is closely related to human-readable English.

C++ can be the base language for many other programming languages that support object-oriented programming features. Bjarne Stroustrup discovered the lack of simulation in Simula 67, the first object-oriented language, and decided to develop it in C++.
C++ is clearly a case-sensitive programming language. For example, cin is used to accept input from an input stream. But if “Cin” doesn’t work. Other languages such as HTML and MySQL are not case sensitive.
C++ is a more compiler-based language than Python. These are C++ programs used to compile and run the executable file. Because of this, C++ is relatively faster than Java and Python.
When a program is executed in C++, variables are allocated dynamic heap space. Variables inside functions are allocated in stack space. Often we don’t know in advance how much memory is needed to store the actual data in a given variable, and the amount of memory needed can be determined at runtime.

This tutorial assumes that you are working on a Linux operating system and that we are writing a multi-threaded C++ program using POSIX. POSIX provides a Threads or Pthreads API available on many Unix-like systems such as FreeBSD, NetBSD, GNU/Linux, Mac OS X, and Solaris.

Two examples are cout in C++ and cin in C++ of the iostream class, which are often used to print output and retrieve data, respectively. These two are very basic input and output methods in C++. To use cin and cout in C++, a program must include the iostream header file.
In the above program, the input operator (<<) inserts the pattern value of the string variable, followed by the string "Computer Science Portal for Geeks" into the output of the standard output stream displayed on the screen.
) and the resulting data is then stored in the variable age on the right-hand side of the subtraction operator.

Selection of CS 12th books is based on the topics you need to know. There are enough books available for students, but they should choose the one that clears their doubts. NCERT provides books for all subjects of 12th class but they don’t have books for 12th computer science so students are free to refer any book which suits them best.
Below are mentioned class 12 computer science chapters
