hi I hve this code

struct Student {
char name[48];
float grade;
int marks[10,5];
char gender;
};

Student s;

Now I have to get the sizeof s

so i added

printf("%d",sizeof(s));

now when I hit compile the result showing is 256

and its wrong because it shoud be 253

as because the size of

char name[48]; ----> 48

and

float grade; -----> 4

and

int marks[10,5]; ------> 200

and

char gender; ------->1

so 48+4+200+1 = 253

so why its telling me 256 ??
