We can define a function like Macro, in which we can pass the arguments. When a Macro is called, the Macro body expands or we can say Macro Call replaces with Macro Body.
Consider the example:
#define CALC(X,Y) (X*Y)
If you are thinking that 1+2 and 3+4 will be evaluated before the expansion and it will be expanded as 3*7 then, you are wrong.
The arguments evaluate after the call, thus Macro CALC(1+2,3+4) will be expanded as = (1+2*3+4) = (1+6+4) =(11).
Finally, the output will be 11.
