How many bytes does int occupy?

In a general computer, int occupies 4 bytes, 32 bits, and the data range is -2147483648~2147483647[-2^31~2^31-1]

In previous microcomputers , int occupies 2 bytes, 16 bits, the data range is -32768~32767[-2^15~2^15-1]

Use printf to output the number of bytes occupied by int:

printf("%d",sizeof(int));

In addition to the int type, there are also short, long, and long long types that can represent integers.

unsigned int represents an unsigned integer, the data range is [0~2^32-1]

What is int?

int is a data type. In programming languages ​​(C, C, Java, etc.), INT is an identifier used to define integer type variables.

Introduction to Bytes:

Byte is a unit of measurement used by computer information technology to measure storage capacity. It also represents a unit of measurement in some computer programming languages. Data types and language characters.

One byte stores an 8-bit unsigned number, and the stored value range is 0-255. Like characters, byte type variables only require one byte (8 bits) of memory space to store.
