Pointers is a type of data in C; hence we can also have pointers to pointers, just we have pointers to integers. Pointers to pointers offer flexibility in handling arrays, passing pointers variables to functions, etc.
We use a series of if statements with an input data register and left shifting 1 into specific bits in order to test individual bits of the input data register to see which key is pressed. This is the importance of being able to test bits of a number to be able to get input from a...
