#include<stdio.h>
#include<conio.h>
#define ABC 20
#define XYZ 10
#define XXX ABC - XYZ
void main()
{
    int     a;
    a = XXX * 10;
    printf("\n %d \n", a);
    getch();
}
I thought the output should be 100 but when i saw the result i found o/p as -80. when i put bracket as #define XXX (ABC-XYZ) then i get output as 100 but without bracket i get o/p as -80.
