Functions have many uses. Although it is possible to write all code within a single function (the main function), code becomes harder to read. By separating the code into smaller, simpler functions with meaningful descriptive names, complex code becomes that much easier to both read and maintain. That is, the code becomes self-documenting so there is less need for comments which would otherwise become a distraction.
Each function should be designed such that it does the absolute minimum amount of work required to fulfil its purpose and does that work as efficiently as possible. Although functions can be expensive to call and return, a well-written function can be inline expanded by the compiler thus eliminating the function call altogether. Thus functions become a programming tool which can drastically reduce the amount of duplicate code we need to write.
Ideally, a function should be small enough so that all the code within that function will fit on screen at once. This usually means writing a huge number of low-level functions that do very little work by themselves, and then using these low-level functions as the building blocks for more complex, higher-level functions.
The c language does not have template functions. That is a c++ thing.
No, because C does not support the concept of template functions. Template functions only exist in C++, never in C.
You can't. HTML is a markup language. C is a programming language. You can make C generate HTML, but C isn't anything like HTML in the way it functions.
c language is the structure oriented language and c does not follows the object oriented paradigms . c++ obeys the all object oriented language characteristics ========== C++ is a set of extensions to the C language to allow some (not all) principles of object-oriented programming to be used. Originally, C++ was a front end pre-processor for C and C++ compilers will translate C language functions.
All these are conversion functions - atoi()-string to integer.itoa()-integer to string.gcvt()-double to string
Impossibility.

compound c language is complicated where we need to use many nested functions and loops
C++ built-in functions are those functions that are provided for you as part of the language itself, and includes all of the C standard library functions (all of which were inherited from C) and is expanded upon by the C++ standard template library. C++ implementors may provide additional functions that are platform-specific, however these are not considered built-in functions becuase C++ is a cross-platform language. These are best described as 3rd party functions. The functions you yourself write are known as user-defined functions.
An identifier is the names given for labels, functions and variables in the c language.
constants, MAX_(function), etc.
Library functions

C date and time functions refer to a group of functions in the standard library of the C programming language that implements time and date operations like conversion between date formats.
Dynamic binding is certainly possible for normal C functions. Binding is a function of the binder (linker) and has nothing to do with the language itself.
