1 9811write a program to swap bits in a character and return the value prototype of function char fun (char a, charb flag c) where fun returns a char, char a is a the value char b is the bit to be changed and flag c is the bit value for eg: x=fun(45,7,0) since 45 is 0010 0101 and ow x should contain the value 65 (0110 0101)
