What else can I help you with?
How to know whether the function is user define function or library function?
You don't have to know. Library functions are also written by somebody, aren't they?
What is the way by which you can make the user defined the size of the arrays?
By using the library function #define A[] we can define the size of arrays
Why main is called user define function?
It simply means that main is not part of a pre-written library like printf or sleep.
How do you know whether the function is 'user define' or 'library functions'?
If you have written it yourself, then it is the former, otherwise it is the latter.
Difference between user defined function or standard c library?
satandard fuction is pre define fuction like getch(),clrscr(), in c++ and userdefine fuction is self created by use to do a particular work ex of use definefuction int add(int a,int b) { int c; c=a+b; return(c); };
What is a library file and give examples?
A library file on a computer is the user's personal file. It could be a series of pictures downloaded to the computer, documents scanned into the computer, or a music file.
Is a header file a collection of built in functions that help in writing c programs?
No. There are no built-in functions in C, there are only built-in types and built-in operators for those types. All functions are user-defined, including those defined by the C standard library. There are no user-defined operators in C, but you can implement operators as named functions if required. A header file (*.h file) typically contains a group of related user-defined function and/or user-defined type declarations which can be included in any source file that requires them. Every user-defined function or user-defined type name used by a program must have one (and only one) definition, usually contained in a corresponding source file (*.c file) or library file (*.lib file). Built-in types and their corresponding operators do not require a header file since they are part of the language itself (hence they are built-in).
In Linux how can I write a shared library function so that when running in user space it and only it can extend a specific data file owned by root user?
If you do not have write access to the file and you are not the owner, then you cannot write to the file with a program running as some other user. Although, setting the setuid bit on the executable of a custom helper program or daemon might be set up in some fashion to do what you want.
What is a powerepoint library?
A PowerPoint library is a side program to power point in which the user can store photos and slides for later use. The library is just another name for a storage file with in the program.
How you can add a user define function in c library?
user defined functions r d functions whch user declare before the main functn in c program... for eg. double min( doub;le x,double y); int factorial( ,) int square(int) etc
Is the main function in C a built-in function or user-defined function?
The main function in C is user-defined. Built-in functions are simply those that do not require a library to be included, but every program must provide a user-defined point of entry; it cannot be built-in. Indeed, most functions in C are user-defined; the built-in functions are mostly operators rather than functions although most do behave like functions. The standard library functions are not built-in either; they all require the inclusion of the appropriate standard library header.
Is it possible to call library function recursively?
There are 2 types of library functions.One system defined & another user defined.In system defined functions we can not determine whether a library function is recursive or not.It may or may not be recursive.But in user defined library functions for example factorial() can be made recursive.No matters whether it is a library function.So if you understand recursion properly then this question makes no sense.
