Bookmark or Share- What range of values can integer types store in C++?To represent the largest value of an "int 4 bytes" on this architecture, you would need 32 ones, meaning (2 x 2^31) - 1 = 4294967295 for the "unsigned long int" data type. ( You would need to write your own binary to decimal conversion program in any language without using pre-defined library or method to understand this more, trust me.
- c++ - What does int & mean - Stack OverflowIt returns a reference to an int. References are similar to pointers but with some important distinctions. I'd recommend you read up on the differences between pointers, references, objects and primitive data types.
- What is the difference between int, Int16, Int32 and Int64?int is a primitive type allowed by the C# compiler, whereas Int32 is the Framework Class Library type (available across languages that abide by CLS). In fact, int translates to Int32 during compilation. Also, In C#, long maps to System.Int64, but in a different programming language, long could map to Int16 or Int32.
- Is the size of C "int" 2 bytes or 4 bytes? - Stack OverflowThe only guarantees are that char must be at least 8 bits wide, short and int must be at least 16 bits wide, and long must be at least 32 bits wide, and that sizeof (char)
- c++ - Difference between the int * i and int** i - Stack Overflowint john = treasure; int *gill = &john; int you = *gill; If you cannot even join gill, but have to contact first jake who can contact gill. int john = treasure; int *gill = &john; int **jake = &gill; int you = **jake; Etc... Pointers are only indirections. That was my last story for today before going to bed :-)
