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.

Detailed explanation of the method of converting int type to bytes in PHP
Mar 06, 2024 pm 06:18 PM
Detailed explanation of the method of converting int type to byte in PHP In PHP, we often need to convert the integer type (int) to the byte (Byte) type, such as when dealing with network data transmission, file processing, or encryption algorithms. This article will introduce in detail how to convert the int type to the byte type and provide specific code examples. 1. The relationship between int type and byte In the computer field, the basic data type int represents an integer, while byte (Byte) is a computer storage unit, usually 8-bit binary data
C++ program to convert double type variable to int type
Aug 25, 2023 pm 08:25 PM
In C++, variables of type int can only hold positive or negative integer values; they cannot hold decimal values. There are float and double values available for this purpose. The double data type was created to store decimals up to seven digits after the decimal point. Conversion of an integer to a double data type can be done automatically by the compiler (called an "implicit" conversion), or it can be explicitly requested by the programmer from the compiler (called an "explicit" conversion). In the following sections, we'll cover various conversion methods. Implicit conversions The compiler performs implicit type conversions automatically. To achieve this, two variables are required - one of floating point type and the other of integer type. When we simply assign a floating point value or variable to an integer variable, the compiler takes care of all the other things
What is the value range of int32?
Aug 11, 2023 pm 02:53 PM
The value range of int32 is from -2 to the 31st power to 2 to the 31st power minus 1, that is, -2147483648 to 2147483647. int32 is a signed integer type, which means it can represent positive numbers, negative numbers, and zero. It uses 1 bit to represent the sign bit, and the remaining 31 bits are used to represent the numerical value. Since one bit is used to represent the sign bit, the effective number of int32 bits is 31.
How to convert int to string type in go language
Jun 04, 2021 pm 03:56 PM
Conversion method: 1. Use the Itoa() function, the syntax "strconv.Itoa(num)"; 2. Use the FormatInt() function to convert int type data into the specified base and return it in the form of a string, the syntax "strconv .FormatInt(num,10)".
How many numbers does java int have?
Mar 06, 2023 pm 04:09 PM
In Java, int is a 32-bit signed data type, and its variables require 32-bit memory; the valid range of the int data type is -2147483648 to 2147483647, and all integers in this range are called integer literals. An integer literal can be assigned to an int variable, such as "int num1 = 21;".
How many bytes does int occupy?
Jan 22, 2024 pm 03:14 PM
The number of bytes occupied by the int type may vary in different programming languages and different hardware platforms. Detailed introduction: 1. In C language, the int type usually occupies 2 bytes or 4 bytes. In 32-bit systems, the int type occupies 4 bytes, while in 16-bit systems, the int type occupies 2 bytes. In a 64-bit system, the int type may occupy 8 bytes; 2. In Java, the int type usually occupies 4 bytes, while in Python, the int type has no byte limit and can be automatically adjusted, etc.

Int in VB refers to a function that takes an integer. Its syntax is such as "int(x)", which means taking the largest integer not greater than x; functions similar to the int function include the Fix function, which deletes the decimal part and returns the remainder. the next integer.
How many bytes does int occupy?
Aug 11, 2023 pm 02:46 PM
int occupies 4 bytes, which means that an int variable can store an integer value ranging from -2,147,483,648 to 2,147,483,647. In some cases, it may also be 2 bytes or 8 bytes. Int is a commonly used Data types are used to represent integers. The appropriate data type needs to be selected according to the specific situation to ensure the correctness and performance of the program.
