Answer 1

#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

Answer 2

constant value cant be changed

Answer 3

#define a 19

const int b = 3

In both cases a y b are constant numbers and you couldn't override them.

Answer 4

Constant value does not change

Answer 5

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.

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

Two problem... 1) u have initiated a macro value named as a and then Changing value to 7
2)int main() should have a return value
