Question

Study of microeconomics assumes that macro variable remains the constant...plz explain with an example .​

Answer 1

Explanation:

Well macros are not exactly variables. They are codes which replace their call occurrences in the program body.

So, for example if you have defined a macro like

#define a 2

And you have used it somewhere in the code like

a=3;

Then the replaced code after compilation will be like

2=3;

And this, as you can imagine, is definitely going to give an error.
