C and Sizeof question..

[Steve Jardine]

Calling all C Gurus!!

Consider this C code:

#include <stdio.h>
main() {

typedef struct {
char           name[256];
char           type[1]; 
int             size;
}resp;

char n[256];
char t[1];

printf("sizeof resp is %d\n",sizeof(resp));
printf("sizeof int is %d\n",sizeof(int));
printf("Total: %d\n", sizeof(int)+sizeof(n)+sizeof(t));
}

Can anyone explain why the sizeof the struct is 264 bytes, yet adding up all of its components yields 261 bytes?
Call me confused...

TIA...
