Is unsigned long 64 bit?
Is unsigned long 64 bit?
Windows: long and int remain 32-bit in length, and special new data types are defined for 64-bit integers.

Is a long 4 or 8 bytes?
It’s standard compliant to have a sizeof(unsigned long) of 8 bytes but the overflow behaves like 4 bytes.
Is Long Long always 64 bit?
The type long long is guaranteed to be at least 64 bits (although the guarantee is formally in the form of the range of values it must be able to represent).
Is a long 32 bits?
int , long , ptr , and off_t are all 32 bits (4 bytes) in size. int is 32 bits in size. long , ptr , and off_t are all 64 bits (8 bytes) in size.
How big is long?

Is 8 a long byte?
According to the standard, long long is at least 64 bits, or say, 8 bytes. On most machines today, it is 8 bytes long.
Is long the same as int32?
The long data type is a 64-bit signed two’s complement integer. The long is a larger data type than int. The difference between int and long is that int is 32 bits in width while long is 64 bits in width.
Is long unsigned integer?
Long signed integer type. Capable of containing at least the [−2,147,483,647, +2,147,483,647] range. Long unsigned integer type. Capable of containing at least the [0, 4,294,967,295] range.
What is unsigned long in C++?
unsigned long. Description. Unsigned long variables are extended size variables for number storage, and store 32 bits (4 bytes). Unlike standard longs unsigned longs won’t store negative numbers, making their range from 0 to 4,294,967,295 (2^32 – 1).
What is the size of an unsigned long on a Mac?
One is a Mac with an intel core 2 Duo Processor and other is a quad-core Intel Xeon Processor running Ubuntu 10.5. They are both 64-bit processors. On the mac, the size of an unsigned long is 4 bytes and the size of an unsigned long long is 8 bytes.
What is the range of an unsigned long variable?
Unsigned long variables are extended size variables for number storage, and store 32 bits (4 bytes). Unlike standard longs unsigned longs won’t store negative numbers, making their range from 0 to 4,294,967,295 (2^32 – 1).
What is the size of a long long in C++?
The C++ standard simply states that sizeof (int) >= sizeof (long) >= sizeof (long long). ISO C++ 1998 does not support long long. ^Whoops, yeah that’s right.
