Question

For each C code fragment, give the final value of the indicated variable after the code fragment is run. If the final value cannot be determine, then give N/A.

A. Final value of ch is ______ (in hex)

char ch = 0x55;

ch = ch << 5;

B. Final value of int_ptr is ______ (in hex)

int my_int = 0x55; // Assume my_int is located at address 0xFC00

int *int_ptr;

my_int = my_int >> 3;

int_ptr = &my_int;

int_prt++;

C. Final value of my_int is ______ (in hex)

int my_int = 0x55; // Assume my_int is located at address 0xFFFE

int *int_ptr;

int_ptr = &my_int;

int_ptr++;

my_int++;

if(int_ptr){

my_int = 0x44;

}

else {

my_int = 0x33;

}

D. Final value of flag is ______ (in decimal)

signed char ch = -128;

char flag = 0;

ch--;

if(50 > ch){

flag = 1;

}

E. Final value of ch is ______ (in decimal)

char ch = 5;

char *ch_ptr = &ch;

ch_ptr = ch_ptr << 16;

if(ch_ptr > 0x7FC0){

ch = 1;

}

Explanation / Answer

1.0xffa0

2.0x23fd78

3.44

4.NULL

5.Invalid operands u cannot compare pointer and integer

ch_ptr = ch_ptr << 16; this cannot be done
