Write a c++ program to get the sizeof an object

            #include  
  
            #define SIZEOF(X)                            \ 
                ({                                       \ 
                    __typeof__(X) x;                     \ 
                    ((char *)(&x + 1) - (char *)&x);     \ 
                }) 
          
  
            int main(void) 
            { 
                struct s { 
                    int x; 
                    float p; 
                    int y; 
                }; 
                printf("%d\n", SIZEOF(struct s)); 
                return 0; 
            }
