How #define stores a variable without using the memory

Question

please explain

Answer 1

Here is an example code:

#define example 1
int main(){
int var=1;
if (var==example)
}
I know this code isn't completely right but it's enough for me to explain. So, anywhere the word example is, it will write 1. It doesn't use memory because once you run the code and you place 1 on every example that there is on the code, you won't need the memory anymore.

I hope I was helpful :)
