Why sizeof int is 4?
So the reason why you are seeing an int as 4 bytes (32 bits), is because the code is compiled to be executed efficiently by a 32-bit CPU.
If the same code were compiled for a 16-bit CPU the int may be 16 bits, and on a 64-bit CPU it may be 64 bits..
How many bytes is a float?
4 bytesSingle-precision values with float type have 4 bytes, consisting of a sign bit, an 8-bit excess-127 binary exponent, and a 23-bit mantissa.
What is a real number in Java?
In mathematics, a real number can be any value along the continuum, such as 4.2 or pi. The integers are a subset of the real numbers. Here are the Java primitives. … An int in Java uses 32 bits and gets you from -2,147,483,648 to 2,147,483,647. The other integral types are similar but with varying numbers of bits.
How big is an unsigned long?
32 bitsUnsigned 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).

Is long 32 bit or 64 bit?
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 a short?
16 bitsIn practice, char is usually 8 bits in size and short is usually 16 bits in size (as are their unsigned counterparts).
What is a CDO big short?
A key instrument of this complex short was a collateralized debt obligation, or CDO. A CDO is a sort of mortgage-backed security on steroids. Whereas, MBS are only made up of mortgages, CDOs can be made up of a diverse set of assets—from corporate bonds to mortgage bonds to bank loans to car loans to credit card loans.
What is range of data type?
Range means the maximum and minimum value that can be stored inside the variable of a given type. For example if you have unsigned char and if we assume that the size of the datatype is 8 bits then you can store values ranging from 0 – 2^8-1 i.e. 0-255 inside it.

Why int is 2 or 4 bytes?
The size of an int is really compiler dependent. Back in the day, when processors were 16 bit, an int was 2 bytes. Nowadays, it’s most often 4 bytes on a 32-bit as well as 64-bit systems. Still, using sizeof(int) is the best way to get the size of an integer for the specific system the program is executed on.
Is big short a true story?
The story chronicles the work of hedge fund manager Michael Burry (portrayed by Christian Bale), who recognizes that the U.S. housing market of the early 21st century is virtually an asset bubble inflated by high-risk loans. … (Baum was based on real-life hedge fund manager Steve Eisman.
Did Mark Baum make money?
He made a fortune when his firm FrontPoint Partners bet against subprime mortgages — as much as $1 billion, The Guardian reported. He was subsequently played in the film adaptation of the book by Steve Carell — albeit with his name changed to Mark Baum.
How many bits is a short?
16 bitsThe size of the short type is 2 bytes (16 bits) and, accordingly, it allows expressing the range of values equal to 2 to the power 16: 2^16 = 65 536. Since the short type is a signed one, and contains both positive and negative values, the range of values is between -32 768 and 32 767.
What is short data type?
short: The short data type is a 16-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive). As with byte , the same guidelines apply: you can use a short to save memory in large arrays, in situations where the memory savings actually matters.
How big is int32?
Int32 represents 32-bits (4-bytes) signed integer. Int32 occupies 32-bits (4-bytes) space in the memory. As per the 4-bytes data capacity, an Int32’s value capacity is -2147483648 to +2147483647.
Why size of pointer is 8 bytes?
The 8-byte count taken up by pointers is crucially exclusive to 64-bit machines, and for a reason – 8 bytes is the largest possible address size available on that architecture. Since one byte is equal to eight bits, 64 bits / 8 = 8 represents the size of a pointer.
