I am learning C language and got the following range of primitive data types:
I dont know where the values in the Range column come from.
If
intis 16-bit, it means there are2^16different values. Of these,2^15 (= 32,768)(half) are negative,2^15 - 1 (= 32,767)are positive and the last one is0.The same reasoning can be used for 8-bit, 32-bit or any other size of integer.
For floating point numbers (float and double), the how the range is explained on Wikipedia or on Steve Hollasch’s page on IEEE Standard 754 Floating Point Numbers.
