List 4 common standard header files in C and state their purpose.
studio.h- standard input / output
stdlib.h- standard library -memory allocation, process control, conversions, etc.
math.h- math functions
string.h- string related functions
conio .h- console input/output
Is C an OOP language?
Is C case sensitive?

What is a kernel in an OS?
A kernel is a computer program at the core of the computer’s operating system with complete control over everything in the system.
What is a general-purpose programming language?

Which earlier language was C derived from?
B (BCPL)
What is an application domain?
An application domain is a mechanism used within the Common Language Infrastructure(CLI) to isolate executed software applications from one another so they do not affect each other.
List 5 common instances where C language is used.
Operating systems Language compilers Assemblers Text editors Databases Web servers
What is a driver in a computer?

What level of language is C? Explain.
C is a high level language.
A high level language enables a programmer to write programs that are independent of a particular type of computer.
High level languages are closer to human languages and further from machine languages, therefore are easier to read, write and maintain.
What is a header file in C code?
A header file has the extension .h and
contains C function declarations and
macro definitions
which are shared between multiple sources.
What are the two types of header files in C?
The files the programmer writes.
