What is a long int?

A long int is a signed integral type that is at least 32 bits, while a long long or long long int is a signed integral type is at least 64 bits. This doesn’t necessarily mean that a long long is wider than a long . Many platforms / ABIs use the LP64 model – where long (and pointers) are 64 bits wide.

What is 32-bit number?

Integer, 32 Bit: Signed Integers ranging from -2,147,483,648 to +2,147,483,647. Integer, 32 Bit data type is the default for most numerical tags where variables have the potential for negative or positive values.

What is 32-bit in 32-bit processor?

1. 32-bit is a type of CPU architecture that is capable of transferring 32 bits of data per clock cycle. … In more technical terms, this means processors can work with 32-bit binary numbers (decimal number up to 4,294,967,295). Anything larger and the computer would need to break the data into smaller pieces.

Why int is 2 or 4 bytes?

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 32-bit and 64 bit integer?

A 32 bit Signed Integer can house a number from −2,147,483,648 to 2,147,483,647 Unsigned: 0 to 4,294,967,295. A 64 bit Signed Integer can house a number from −9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Unsigned: 0 to 18,446,744,073,709,551,615.

Is int always 4 bytes?

Nowadays in most of compilers int is of 4 bytes. If you want to check what your compiler is using you can use sizeof(int) .
