WitrynaC/C++ provides various data types that can be used in your programs. In general, you'd commonly use: int for most variables and "countable" things (for loop counts, variables, events) ; char for characters and strings ; float for general measurable things (seconds, distance, temperature) ; uint32_t for bit manipulations, especially on 32-bit registers ; … WitrynaThe following data types are flexible: they have no predefined size and the data they describe can be of different length in different arrays.(In the character codes # is an integer denoting how many elements the data type consists of.). class numpy. flexible [source] #.
