For this problem, assume that you are developing code in the C language for a 32-bit CPU such as the PIC32. Also assume that you are using an integer named k, which has been initialized. As usual, bit position 0 refers to the least-significant bit. a) Write a single instruction that will set bit 4 and bit 5 of k to 1, without affecting any other bits of k. b) Write a single instruction that will clear bit 4 and bit 5 of k to 0, without affecting any other bits of k. c) Write a single instruction that will clear the most significant bit of k to 0, without affecting any other bits of k. d) Write a single instruction that will set all bits in the most-significant byte of k to 1, without affecting any other bits of k. e) Write 1 or 2 instructions that will cause the least-significant byte of k to contain the bit pattern 11110000, without affecting any other bits of k
