|C++ Programming basic Concepts and Questions|
What is C++ programming languageQuestion : What is a Program or a Software?
Answer : Set of instructions given to the computer to solve any problem is called a program. A program is written in a computer language
Question : Define programming languages ?
Answer : User can learn and understand high-level language(HLL) easily.
The instruction of high-level language are written in English Statements.
The programs of high-level language are not directly executed on the computer. A language translator is required to translate the high-level language into low level language.
Question : What is low-level language (LLL)?
Answer : A language which is close to machine language
The low level language requires a deep understanding of the machine architecture.
Question:What is machine language ?
Answer : It is the native language of computer .
Every machine language instruction consist of 0's and 1's.
It is difficult for human beings to understand and learn it.
And it is also difficult to locate remove errors in the program.
It is directly executed by the computer. The machine language programs are machine dependent.
What is program portability in C++Question : What is meant by program portability?
Answer : The programs written in high-level language are closed to human language and programs are machine independent i.e. a program can be run o different types of computers this is called program portability.
What is source code in C++
Answer : The computer does not understand the source code.
The source code is converted into machine code and then it is directly executed ton the computer.
What is Object Code in C++
Question : What is Linker C programming?
Answer : The linker is a program that combines the object program with additional library files and produces one executable file with .exe extension.
Linking is a process is which the object file is produced by the compiler is linked to many other files by linker.
Answer : For execution, the loader loads the executable files in the memory.
It is also system software in turbo c++ compiler Ctrl+F9 key is used to load and run the program.
The executable file (.exe) runs directly on the computer after loading process.
