Why is size of int different?

Yes, it depends on both processors (more specifically, ISA, instruction set architecture, e.g., x86 and x86-64) and compilers including programming model. For example, in 16-bit machines, sizeof (int) was 2 bytes. 32-bit machines have 4 bytes for int .

What is the size of float in a 32-bit compiler?

What is difference between 32-bit and 64-bit operating system?

A 32-bit system can access 232 different memory addresses, i.e 4 GB of RAM or physical memory ideally, it can access more than 4 GB of RAM also. A 64-bit system can access 264 different memory addresses, i.e actually 18-Quintillion bytes of RAM.

What is size and range of float data type?

Floating-Point Types

Type	Storage size	Value range
float	4 byte	1.2E-38 to 3.4E+38
double	8 byte	2.3E-308 to 1.7E+308
long double	10 byte	3.4E-4932 to 1.1E+4932

Why do integers take 2 bytes?

So, size of int data type is 2 bytes means that the compiler uses two bytes to store a int value. The value can be anything; it can be zero or one hundred but two bytes would always be used to keep it in memory. Now each bit in binary can either be 0 or be 1. That means 1 bit can hold only two numbers: 0 and 1.

How many bytes float takes in C?

4 byte
Floating-Point Types

Type	Storage size	Precision
float	4 byte	6 decimal places
double	8 byte	15 decimal places
long double	10 byte	19 decimal places
