Here, the sizeof() are displayed. All of them work except sizeof(pointer). I get "undeclared identifier 'pointer'" error for the printf line. How can I fix this?Code:#define aVar sizeof(char) #define bVar sizeof(short) #define cVar sizeof(int) #define dVar sizeof(long) #define eVar sizeof(float) #define fVar sizeof(double) #define gVar sizeof(pointer) #define hVar sizeof(struct student) int main(int argc, char *argv[]) { char response; do { printf("On this machine the number of bytes in a char is: %d\n", aVar); printf("On this machine the number of bytes in a short is: %d\n", bVar); printf("On this machine the number of bytes in a int is: %d\n", cVar); printf("On this machine the number of bytes in a long is: %d\n", dVar); printf("On this machine the number of bytes in a float is: %d\n", eVar); printf("On this machine the number of bytes in a double is: %d\n", fVar); printf("On this machine the number of bytes in a pointer is: %d\n", gVar); printf("On this machine the number of bytes in a struct student is: %d\n", hVar); printf("Would you like to see the information again?"); scanf("%c", &response); switch (response) { case 'y': scanf("%c", &response); break; default: printf("Goodbye"); return 0; break; } }while(response = 'y'); }
And while we're here, is my code good or bad? Is there any way to shrink or make it efficient? Thanks
