What does ANSI C refer to?
The version of the C language standardized by the American National Standards Institute in 1989, also known as C89 or ISO C90.
ANSI C was designed to provide a consistent programming environment.
What was the purpose of the ANSI C standard?
To offer a consistent and reliable programming environment that can produce code which works with minimal adjustments on different systems.
This standard aimed to ensure portability across various platforms.
How many header files are included in the ANSI Standard?
24 header files.
These header files provide essential functionalities for C programming.
What does the C standard library of ANSI include?
A comprehensive set of functions for:
* Input/output operations
* String manipulation
* Memory allocation
* More
This library is crucial for performing various programming tasks.
Which header file is commonly used for input/output operations in C?
include<stdio.h></stdio.h>
This header file is essential for using standard input and output functions.
Which header file is commonly used for memory allocation in C?
include<stdlib.h></stdlib.h>
This header file provides functions for dynamic memory management.
What is C99?
A newer standard of the C language released by the International Organization for Standardization in 1999.
C99 introduced several enhancements to modernize the language.
What are the main purposes of C99?
To extend the language with new features, improve safety, and support new hardware architectures and programming paradigms.
C99 aimed to make C more versatile and secure.
What new data type was introduced in C99 for better integer support?
long long int for 64-bit integers.
This allows for handling larger integer values than previous standards.
What are fixed-width integers introduced in C99?
Data types such as int8_t and int16_t.
These types provide a standardized way to define integers of specific sizes.
What is a character set in C?
A package of valid characters recognized by the compiler/interpreter.
It is fundamental for building program elements in C.
What are the building blocks of a C program?
Characters, which form:
* Constants
* Variables
* Expressions
These elements are essential for writing C code.
What types of characters are categorized in C?
The characters available in C are categorized into:
* Letters/Alphabets
* Digits
* Special symbols
* Whitespace characters
This categorization helps in understanding how different characters can be used in programming.
