2. Setting a bit to 1 Write a function that accepts as input an unsigned char, and an integer bitNum (range 0-7) and using the "shift" and "or" operators sets the bit at position bitNum to 1. The function returns modified character. For example, if the bit sequence of a char is 00010100 and bitNum5 then the answer should return 00110100. Function prototype unsigned char setBit(unsigned char c, int bitNum)
