int and long

The data model determines the correspondence between the basic data type and the data width in C language. The 32-bit model we use is called ILP32, while 64-bit models have three kinds: LP64, LLP64, and ILP64. In a 64-bit model, the pointer must be 6

Today in the time stamp of the conversion program to find out how to write the wrong, only to find the originalLong A1 = 10;This code does not directly transform 10 into a long, allocated memory or int lengthNeed to write long a1 = 10L;The errors

Write a program to determine the ranges of char, short, Int, and long variables, both signed and unsigned, by printing appropriate values from standard headers and by direct computation. harder if you compute them: Determine the ranges of the

Conversion source code between byte and INT in Java: // Mutual conversion between byte and INT public static byte inttobyte (int x) {return (byte) x;} public static int bytetoint (byte B) {// Java always treats byte as a byte; we can binary it and 0

Bo Master this time to write some C program code, because before the C is not a lot of understanding, it encountered a lot of bottlenecks, of course, there are many interesting methods can be used to solve these problems, the following problem is

A problem occurs when a program running properly on a 32-bit machine fails on a 64-bit machine. So I found this article about transplantation and took a good look. Original post address: http://queniao.blog.51cto.com/10636/126564 In fact, there is

1. The integer types in C language include char, short, Int, long, etc. The following section describes the C language's requirements for the length of each data type:(A). The short and long types have different lengths.(B) The Int type is usually

64-bit programming in front of the 32-bit world in the new era Author: Xie Qidong Source: topic network responsibility Editor: Ark 　　Write portable code for 16, 32, and 64-bit Architectures Compared with 16-bit, 32-bit means faster programs, more

For ix86 programming, sometimes it is necessary to change from the real mode to the protection mode (for example, to access extended memory in the DOS era, or to write pilot code, of course, if you program in a 32-bit operating system, you won't be

Reading Tips: with the advent of a low-cost 64-bit platform, coupled with the falling price of memory and hard disk, it is undoubtedly a great effort for 32-bit programs to port 64-bit hardware, those scientific operations, databases, and programs

In general, the data types in Python are grouped into the following categories: Number (numeric) includes Int,long,float,complex string (string) such as: Hello, "Hello", and hello list (list) for example: [[+] , [1,2,3,[1,2

1. Implicit conversion c is implicitly converted in the following four scenarios: 1, in arithmetic expressions, the low type can be converted to a high type. 2 . In an assignment expression, the value of the right expression is automatically

Yesterday saw a topic: calculate 1234!, can't use the BigInteger classIt is well known that factorial data can be very large, and the commonly used int and long types are not sufficient at all. Generally think of only BigInteger class, but the topic
