A macro is a fragment of code which has been given a name. Whenever the name is used, it is replaced by the contents of the macro. There are two kinds of macros. They differ mostly in what they look like when they are used. Though macro and functions sound similar but macro is a preprocessed and functions...

They differ mostly in what they look like when they are used. Though macro and functions sound similar but macro is a preprocessed and functions are compiled. Before compilation macro name is replaced by macro value but during function call , transfer of control takes place. read less

Function is a set of instruction .macro functions means a small function the entire c program is divided into small partitions each part is call as a macro. each marci has its own set of instructions. when ever you define macros in header by #define macro the value of macro is automatically get used in ur program Ex. If u want to find 2pir value just u need r variable and it's value. Why beacsuse already pi value is evaluated in pi macrofunctions So just u need to define at header file then were ever pi comes it automatically takes 3.14 as pi value Like this we can create sapate macro functions and we have to save those functions in macro directory. Then I should define and use the value of functions read less

To create a macro function, simply define a macro with a parameter that has whatever name you like, such as my_val. For example, one macro defined in the standard libraries is abs, which returns the absolute...

For example, one macro defined in the standard libraries is abs, which returns the absolute value of its parameter. Let us define our own version, ABS, below. (Note that we are defining it in upper case not only to avoid conflicting with abs, but also because all macros should be defined in upper case, in the GNU coding style. See Style.)
