Can i define multiple macros in one line in c or c++?

Question

Like we can declare multiple integers in one line
Int a,b,c; so how can i declare multiple macros?

Answer 1

No. Macros are different from language statements they are preprocessed and use whitespace to delimit tokens(single elements)

Macro definition must start and end with a new line.

A single macro can span multiple lines by using `\` but, multiple macros can't share single line.

#include<stdio.h>
#define spam while(1)\
printf("%d",0);

int main() {
spam
return 0;
}
