Give the minimum size of each of the following C++ types. char has 1 byte, short has 2 bytes, int & float has 4 bytes, double & long has 8 bytes, pointer has 4 bytes.

a) struct sl_type {
long i;                                8 bytes
char ch;                        +   1
int *ip;                          +   4
};                                    13  bytes

b) union u_type {
float f;                                 4 bytes
char *cp;                          +4
short s[3];              +2(3)=  6
double d;                            8
};                                      22 bytes

c) struct s2_type {
u_type u;                      22 bytes
float *fp;                  +    4
long n;                       +   8   
char c[15];                +  15
sl_type t;                   +  13
                                    62 bytes
};
