#define is a macro that when used in the expression/statement is replaced. So your statement becomes const int 19 = 7; Which results in an error

#define a 19 const int b = 3 In both cases a y b are constant numbers and you couldn't override them.

You replace a by 19. So in your code really stands written: 19 = 7; And you can't assign a number to another number, only to a name.

You can't redeclare const variable inside int main or anywhere, delete const int a or change a to something else

You cannot redeclare a preprocessor macro as constant in a function.

You define 'a' as 19 already So no matter you define it constant or anything it take it as 19

#include <stdio.h> const a=19; int main() { const int a=7; printf("a=%d",a); }U should write const keyword
