Re: Difference between C and advanced C

hello sir,

Sir will please tell me the exact difference between
C and advanced C...

The exact difference is the word "advanced" followed by an extra space.

what are the extra features or funcions...etc added
in this advanced one.

None. C is C.

It occurs to me that you may mean the revision to the Standard that
occurred in 1999. If so, bear in mind that the jury is still out on
whether this constitutes an "advance" and that implementation support for
C99 is minimal, but the major changes it introduced are:

- restricted character set support via digraphs and <iso646.h>
(originally specified in AMD1)
- wide character library support in <wchar.h> and <wctype.h>
(originally specified in AMD1)
- more precise aliasing rules via effective type
- restricted pointers
- variable-length arrays
- flexible array members
- static and type qualifiers in parameter array declarators
- complex (and imaginary) support in <complex.h>
- type-generic math macros in <tgmath.h>
- the long long int type and library functions
- increased minimum translation limits
- additional floating-point characteristics in <float.h>
- remove implicit int
- reliable integer division
- universal character names (\u and \U)
- extended identifiers
- hexadecimal floating-point constants and %a and %A printf/scanf
conversion specifiers
- compound literals
- designated initializers
- // comments
- extended integer types and library functions in <inttypes.h> and
<stdint.h>
- remove implicit function declaration
- preprocessor arithmetic done in intmax_t/uintmax_t
- mixed declarations and code
- new block scopes for selection and iteration statements
- integer constant type rules
- integer promotion rules
- macros with a variable number of arguments
- the vscanf family of functions in <stdio.h> and <wchar.h>
- additional math library functions in <math.h>
- floating-point environment access in <fenv.h>
- IEC 60559 (also known as IEC 559 or IEEE arithmetic) support
- trailing comma allowed in enum declaration
- %lf conversion specifier allowed in printf
- inline functions
- the snprintf family of functions in <stdio.h>
- boolean type in <stdbool.h>
- idempotent type qualifiers
- empty macro arguments
- new struct type compatibility rules (tag compatibility)
- additional predefined macro names
- _Pragma preprocessing operator
- standard pragmas
- _ _func_ _ predefined identifier
- VA_COPY macro
- additional strftime conversion specifiers
- LIA compatibility annex
- deprecate ungetc at the beginning of a binary file
- remove deprecation of aliased array parameters
- conversion of array to pointer not limited to lvalues
- relaxed constraints on aggregate and union initialization
- relaxed restrictions on portable header names
- return without expression not permitted in function that returns a value
(and vice versa)
