I notice that there are different data types. And I am assuming there fore storing data (obviously), but my question is, if you need to store a piece of data that doesn't require a short data integer (signed: -32768 to 32767
unsigned: 0 to 65535), but could be put into a char (signed: -128 to 127
unsigned: 0 to 255) which could take less space. Would the program be faster if you be more precise? Or is it just the calculations that make the program faster or slower? If it totaly flew by my head, and you know it, could you give me a better definition on how it works?
