WebIn 32 bit processor, it can access 4 bytes at a time which means word size is 4 bytes. Similarly in a 64 bit processor, it can access 8 bytes at a time which means word size is 8 bytes. Structure padding is used to save number of CPU cycles. What we know is that size of a struct is the sum of all the data members. Like for the following struct, WebTypes & Description. 1. Basic Types. They are arithmetic types and are further classified into: (a) integer types and (b) floating-point types. 2. Enumerated types. They are again arithmetic types and they are used to define variables that can only assign certain discrete integer values throughout the program. 3.
