1) What is C language?
C is a
mid-level and procedural programming language. The Procedural programming
language is also known as the structured programming language is a technique in
which large programs are broken down into smaller modules, and each module uses
structured code. This technique minimizes error and misinterpretation
2) Why is C known as a mother language?
C is
known as a mother language because most of the compilers and JVMs are written
in C language. Most of the languages which are developed after C language has
borrowed heavily from it like C++, Python, Rust, javascript, etc. It introduces
new core concepts like arrays, functions, file handling which are used in these
languages.
3) Why is C called a mid-level programming
language?
C is
called a mid-level programming language because it binds the low level and high
-level programming language. We can use C language as a System programming to
develop the operating system as well as an Application programming to generate
menu driven customer driven billing system.
4) Who is the founder of C language?
Dennis
Ritchie.
5) When was C language developed?
C
language was developed in 1972 at bell laboratories of AT&T.
6) What are the features of the C language?
The main
features of C language are given below:
- Simple: C is a simple language because it follows the structured approach, i.e., a program is broken into parts
- Portable: C is highly portable means that once the program is written can be run on any machine with little or no modifications.
- Mid Level: C is a mid-level programming language as it combines the low- level language with the features of the high-level language.
- Structured: C is a structured language as the C program is broken into parts.
- Fast Speed: C language is very fast as it uses a powerful set of data types and operators.
- Memory Management: C provides an inbuilt memory function that saves the memory and improves the efficiency of our program.
- Extensible: C is an extensible language as it can adopt new features in the future.
7) What is the use of printf() and scanf()
functions?
printf(): The printf() function is used to
print the integer, character, float and string values on to the screen.
Following
are the format specifier:
- %d: It is a format specifier used to print an integer value.
- %s: It is a format specifier used to print a string.
- %c: It is a format specifier used to display a character value.
- %f: It is a format specifier used to display a floating point value.
scanf(): The scanf() function is used to
take input from the user.
