Tipical v.r. for int: -2^15 .. 2^15-1 or -2^31 .. 2^31-1

Of course all of these are platform-dependent.
There are far more than 4 integral types in C++. As of C++11, there were 27 integral types: bool char signed char unsigned char wchar_t char16_t char32_t short signed short unsigned short short int signed short int unsigned short int int signed int unsigned int long signed long unsigned long long int signed long int unsigned long int long long signed long long unsigned long long long long int signed long long int unsigned long long int

They are both integral types however they may have different lengths (in bytes) such that an int is guaranteed to be at least as long as a short. Note that the name, short, is actually a modifier rather than a type and literally means a short int. The other modifiers are long, signed and unsigned. When modifiers are used without an explicit type, int is implied. This is in common with C where int is the default type. On most implementations, a char is 1 byte in length, a short is 2 bytes and an int is 4 bytes. sizeof(char)==1 can be guaranteed across all implementations but the lengths of all other integral types are implementation-defined. All we can guaranteed is that the relationship between their respective lengths is as follows: char <= short <= int <= long <= long long Note that the signed or unsigned modifiers do not affect integral lengths in any way, they simply change the interpretation.
The int is a data type in c, c++ or java, It can divided in to two parts that is short and long. Int short if of same size as int (2).
The size (and value-range) of int is platform-dependent, whilst that of int32_t is fixed.
For example 'int' is a data-type, 'short', 'long', 'signed' and 'unsigned' are modifiers, 'extern', 'auto', 'static', 'register' are storage-classes. The declarations go like this: storage-class modifiers data-type identifier example: static unsigned short int x;
Are you sure that these words (normal int and regular int) actually mean something?
int short byte long
It depends on the programming language, the compiler, and the machine architecture. In C, the size of short int and int is not mandated by the language. Often, on 32-bit machines, 'int' will be 32-bit, while 'short int' may be 16-bit. But the only thing the language promises is that short int will be no larger than int.
You probably mean 'bit' rather than 'byte'.The difference is that 32-bit variables can store more data than 16-bit ones.16-bit types include short int and short (same thing). Short int can store numbers -32768 to 32767.32-bit types are now the default and include int, long int (same thing now), long (same thing again), float, and (usually) pointers. Ints (and long ints) can store numbers -2,147,483,648 to 2,147,483,648.The difference is that 32-bit data values are less likely to overflow, wrapping around from the highest number to lowest, and should usually be used unless there's some pressing reason not to. A person's age could be stored in a short int without fear of going into the thirty thousands, but not their income.So, the rule of thumb is to stick with int and float and master them before venturing into the less used (but still useful) other types.
There are four modifiers in C++: long, short, signed and unsigned. They are used to modify primitive types (int, char, float and double) to change their behaviour. If no type is specified, int is assumed. Thus a long long turns a 32-bit integer into a 64-bit integer while unsigned ensures an integer is always in the positive range.
