functions which have been modified by using different return types
formatted functions::: Follows a fixed format like scanf,printf Unformatted functions:::Do not have fixed format like gets,getchar
Disks and partitions should be formatted before usage.

formatted
Formatted input and output functions in programming languages allow for specific formatting options to be applied to the data being read from or written to the console. These functions enable the programmer to control the appearance of the data, such as specifying the number of decimal places when outputting a floating-point number. On the other hand, unformatted input and output functions simply read or write data without any specific formatting instructions, resulting in a more basic representation of the data on the console. The choice between formatted and unformatted functions depends on the desired level of control over the appearance of the data being processed.
The printf() function prints a formatted string.
Yes, there can be friend functions in C++.
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.
C programs do not function without functions.
No, because C does not support the concept of template functions. Template functions only exist in C++, never in C.
%f is used as a format mask to represent a floating point number.Any of the "formatted" io functions can use this: printf, fprintf, scanf, etc.Example:float n = 1.5;printf("%f", n); // prints the value of n
Not possible in C, only in C++
