A global variable is a place of data storage which multiple modules of application (sometimes all modules) can access to read and modify the variable's content.
A macro is something altogether different. A macro is a set of instructions, typically used to save keystrokes when coding, and to maintain code readability. While macros can reference, declare or use variables (including global variables), macros and variables are quite different and cannot be compared.

What is micro and how it is different from c variable name?
A macro is a variable that has a constant value throughout the program whereas a C variable is an identifier whose value can differ from function to function, it can be incremented or decremented whereas the value of a macro remains same .
What is enclosed between a macro header statement and a macro end statement?
The macro content.
What is null macro?
The NULL macro is an implementation-defined macro. It is used to symbolise the zero address (0x0) in C programs and older C++ programs. It is not type safe, but is the conventional method of assigning the zero address to a pointer variable. C++11 introduced the type-safe nullptr data type.
What is the difference between mirco and macro?

How you can interchange two integer values using swap variable in c language?
t = a; a = b; b = t; // t is a third integer variable (swap variable) But here's a way without a swap variable, given as as a macro in C: #define SWAP(a,b) { if (a!=b) { a^=b; b^=a; a^=b; }} // Swap macro by XOR Once you define it, you can say swap(x,y) to swap x and y. The numbers kind of flow through each other and end up swapped.

How does the structures of macro-molecules act as an index of relatedness between species?
The structures of macro-molecules, such as DNA and proteins, can be used to infer relatedness between species because they are inherited from common ancestors. By comparing the similarities and differences in the sequences of these molecules among different species, scientists can construct phylogenetic trees that show the evolutionary relationships between them. Closer related species tend to have more similar macro-molecular structures than distantly related species.
What are the hedge funds in Barbados?

What are the main differences between a macro lens and a regular lens, and how do these differences impact the quality of close-up photography?
A macro lens is specifically designed for close-up photography, allowing for a higher level of magnification and detail compared to a regular lens. The main differences lie in the minimum focusing distance and magnification ratio. A macro lens can focus much closer to the subject and achieve a 1:1 magnification ratio, capturing small details with sharpness and clarity. This results in higher quality close-up images with greater depth of field and minimal distortion.
