Given a PIN (value in HEX) and bit number, we have to SET and then CLEAR given bit of the PIN (val) by using Macros. Macros definitions #define SET(PIN,N) (PIN |= (1<<N)) #define CLR(PIN,N) (PIN &= ~(1<<N))
In other programming languages, we can define a specific set of values. To define infinity, we can use float("inf") to define a positive infinite number and for a negative infinite number, we use float("-inf"). Now, we will look at how it works in Python. Suppose we have a value...
