What is default int size?
int: By default, the int data type is a 32-bit signed two’s complement integer, which has a minimum value of -231 and a maximum value of 231-1.
What is size of int in C++?
The int and unsigned int types have a size of four bytes. However, portable code should not depend on the size of int because the language standard allows this to be implementation-specific. C/C++ in Visual Studio also supports sized integer types.
Is int always 32-bit?
int is always 32 bits wide. sizeof(T) represents the number of 8-bit bytes (octets) needed to store a variable of type T .
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.
What is an int 11?
in int(11), 11 is the display width of the integer column, unlike the characters columns where the number means number of character that can be stored. int(11) – The number in the parenthesis i.e () does not determines the max and min values that can be stored in the integer field.

What is bigger than an int?
If you need to hold an integer larger than the Integer data type can hold, you can use the Long data type instead. Long variables can hold numbers from -9,223,372,036,854,775,808 through 9,223,372,036,854,775,807. Operations with Long are slightly slower than with Integer .
