#30: Preprocessor and Macros | C Programming for Beginners

In this video, we will learn about preprocessors and macros. We have been using preprocessor in all our programs. Similarly, we will learn about macros, macros are a piece of code that is given some name. For example, #define PI 3.1415, here PI is a macro. So, from this video, you will know the exact meaning and use of preprocessor and macros with specific examples.

Python has a module named datetime to work with dates and times.

Even though date and time may seem simple and straightforward in our daily use cases, they can be challenging to implement in our code because we have to keep a record of things such as different date and time formats, different time zones and so on. Fortunately, Python provides a built in datetime module to simplify this task.

In this video, we will use the datetime module to manipulate date and time in Python with the help of examples.
