You will need to fill in the body of setBit(). The input will be a byte (i.e., 8 bits) input, a single bit bit, and an integer n, and you will need to set the n-th bit of input (0-based counting from the right) to bit and return the result.

For example, if input is 85 (i.e., 01010101), n is 3, and bit is 1, the result would be 93 (i.e., 01011101).

Please do the solution in C++ and explain/comment your code. Thanks.
