a. Binary representations of variables a - The initial value of a is not assigned. In C, uninitialized variables will contain garbage values. These values can vary depending on the compiler and environment. So, the binary representation of a is indeterminate. b - b is assigned the value a + 0x12 . Since the value of a is indeterminate, the binary representation of b is also indeterminate. c - c is assigned the value a + 0xf0 . Similar to b , the binary representation of c is indeterminate due to the unknown value of a . d - d is assigned the value 0xc1 . So, the binary representation of d is 11000001 . e - The value of e is obtained by left shifting the value of a by 1 bit. Since the value of a is indeterminate, the binary representation of e is also indeterminate. f - The value of f is similar to e where it's obtained by left shifting the value of a by 1 bit. So, the binary representation of f is indeterminate. b. Output of the program The program will produce the following output: 1_a (undefined) 2_a 0x<value of a in hexadecimal> 3_b (undefined) 4_b <value of b in decimal> 5_c (undefined) 6_c <value of c in hexadecimal> 7_d= 0xc1 8_e (undefined) 9_f= (undefined) c. Explanation of outputs 5_b : Since the value of a is not initialized, the output of 5_b will be an undefined character. 8_e : Similar to 5_b , the output of 8_e will also be an undefined value because the value of a is left-shifted by 1 bit. 9_f : The output of 9_f is also undefined due to the unknown value of a which is left-shifted by 1 bit.
