short integer range

Today I will review the variables and basic types of C ++, and then look at the integer. Generally, the data type that represents an integer is called an integer, but in fact, an integer in C ++ includes an arithmetic type that represents an

There are four kinds of integer types in Java, which are byte short int long, where byte is only one byte 0 or 1, which is not explained in detail here. The other three types are as follows: 1,Basic type: Short bits number: 16Packing class:

Short shaping on 32-bit PCs is 2 bytes, each byte is 8 binary bits, a total of 16 bits 16 bits, can represent the number of numbers is 0 ~ 2^16-1, that is 0 ~ 65535 a total of 65,536, if the positive and negative integer each half, That is a

1. Brief Introduction The range of Integer type was asked two days ago, and it was definitely despised. It looks good to come back. Here is a summary. 2. unsigned integer On a 32-bit general machine, unsigned short int (2 bytes), unsigned int (4

First, analyze the characteristics of the basic data type, maximum and minimum values. 1, Basic type: int bits number: + Wrapper class: Java.lang.Integer Minimum: integer.min_value=-2147483648 (-2 of 31 Parties) Maximum value: integer.max_value=

The various symbolic constants are defined in the header file Climits (limits.h) in a macro definition to represent the range of various integer type representations, such as the maximum minimum value of int, the maximum minimum value of long, and

System and software security has always been a difficult problem in the security field and has a high learning threshold. Lab mavericks @ reallybobo offer us integer errors in easy-to-understand languages and how to cause

1. BackgroundBefore the end of the day, the database has a temporary table cert_display_tmp used to do the interface display, the table data is from T_cert_sample, Ying said the data is incorrect, and then manually perform the update function,
