Interview of Programming C-Language

Interview programming C-language

Interview question of C-language. Today we discuss interview of programming C-language start before answering and question if you don’t know c programming language please visit my previous article where I tell complete detail of C programming language. I mention all the article list below. If you like please share this article and follow me.

What is a computer program?

A set of instructions given to the computer to perform a particular task is called a computer program or software.

What is a computer programming language?

A programming language provides the way of communication between user and computer. A computer program is written in a programming language. The programming language provides a set of rules for writing computer programs.

List some characteristics of high-level programming language.

A list of some characteristics of high-level programming language is given below.

Easy to learn

Easy to detect errors

Machine-independent

Availability of library functions

Shorter programs

Well-defined syntax and standard

Source code is understandable by another programmer.

What are header files?

The header files contain the declarations or information of standard library functions

The extension of a header file is “h”.

What is the use of “include” directive?

The include directive is used to include the specified header file in the program. It means that this preprocessor directive causes the preprocessor to insert the definition of standard function into C program from a standard library.

What is constant macro?

The define directive is an important preprocessor directive. It is used to define a constant known as constant macro. A constant macro is an identifier, which is assigned a particular constant value. The value of identifier remains constant during the execution of program.

What are delimiters?

The body of the function is surrounded by braces. These braces are called delimiters. The left brace indicates the start of the body of the function, whereas the matching right brace indicates the end of the body of the function.

What is meant by statement terminator?

Every statement of C program must be terminated with semicolon (;) it is called statement terminator. If any of the statement is missing the statement terminator (;), the following error message will be reported by compiler during compiling process.

What is meant by IDE?

IDE stands for integrated development environment. The environment in which a computer program is written, compiled, executed, tested, and debugged is called integrated development environment.

What is the use of TC editor?

Turbo C or KC editor provides a complete ide to create, edit, save, compile and run C programs. It is called the TC editor. TC editor also provides a powerful debugging feature. This means that it helps to detect and remove errors in the C program.

What is meant by editing a program?

You can also make changes during writing new programs as well as in the existing c program. Therefore, the process of writing, changing and revising the source code is called editing.

What do you know about linker?

The linker is a program and is a part of compiler. It links object file to the required library files. After linking the object code to the libraries, an execrable file with extension EXE is created.

What is syntax errors?

In C program, there can be many causes of syntax errors. For example:

Missing semicolon at the end of statement.

Missing any of the delimiters i.e

Incorrect spelling of Andy keyword

Using variables without declaration etc.
