unexpected tokens following preprocessor directive - expected a newline

this is my code.

#include <stdio.h>
#include <stdlib.h>

int main(void) {
int a, b, somma, massimo;
printf("Inserire il primo valore: A =");
scanf_s("%d", a);
printf("Inserire il secondo valore: B =");
scanf_s("%d", b);
if (b > 0) {    //1
    printf("B = %d e positivo", b);
} else {
    printf("B = %d e negativo", b);
}
if (a % 2 == 0){    //2
    printf("A = %d e pari", a);
} else {
    printf("A = %d e dispari", a);
}
somma = a + b;  //3
printf("A + B = %d", somma);
if (a < 0) {    //4
    a = -a;
}
if (b < 0) {
    b = -b;
}
massimo = a + b;
printf("Il numero più grande ottenibile con questi due numeri A, B e %d", massimo);
}

when i try to compile it gives me this warning:

1>c:\users\mario\documents\visual studio 2015\projects\controlla a e b\main.c : error C4335: Mac file format detected: please convert the source file to either DOS or UNIX format

Along with the wrong encoding type, this warning can also generate with incorrect end of line sequence. So try changing the same.

In VSCode, on the bottom-right click on CRLF (or LF depending on the default setting). A popup will appear; choose the required sequence.

I found that this error can appear due to a poorly constructed #define, such as:

#define USE_THIS  true;

...

#if USE_THIS
<some code>
#endif

Obviously you don't use the semicolon.

This is not exactly relevant to the above example, but I included it here just in case someone searches for this error message.

Remove all non-ASCII characters from your files or set your editor and compiler to accept UTF-8.
