1. Implement and test the following functionalities through C code fragments. a) Write a C code fragment to check a bit value. Declare three character type variables ch1, ch2 and mask with initial values of 0x34 and 0x20 for chl and mask, respectively. C code should set character type variable ch2 to 1 if the bit 5 in mask is 1, otherwise 0. Note that bits in a byte are numbered from 0 (lsb) to 7 (msb). b) Write a C code fragment to set a bit value. Declare two character type variables chl and mask with initial value of 0x34 for ch1. C code should set bit 7 in variable ch1 to 1 using mask without changing any other bit values in chl. c) Write a C code fragment to clear a bit value. Declare two character type variables chl and mask with initial value of 0x34 for ch1. C code should clear bit 3 in variable ch1 to 0 using mask without changing any other bit values in chl. d) Write a C code fragment to toggle a bit value. Declare two character type variables ch1 and mask with initial value of 0x34 for ch1. C code should toggle bit 4 in variable chl using mask without changing any other bit values in chl.
