6.1 Why do we need octal and hexadecimal? In programming, we usually use 10 hexadecimal notation ...... C/C ++ is a high-level language. For example: Int A = 100, B = 99; However, because the representation of data in a computer exists in binary format, sometimes binary can be used to solve the problem more intuitively. However, the binary number is too long. For example, intType occupies 4 bytes, 32 bits. For example, if the value is 100, the value

octal and hex are used in thisDerived from the relationship, that is, a three-bit binary representation of an octal, with a four-bit binary representation of a hexadecimal number.Next, remember 4 numbers 8, 4, 2, 1 (23=8, 22=4, 21=2, 20=1). Now let's practice the conversion between binary and octal.(1) binary into octalMethods: Take the Triad method, that is, fr

Binary, octal, decimal, hexadecimal conversion, binary hexadecimal1. Preface The most boring thing during each holiday is that you don't want to get up or eat. Founder just doesn't want to move, lie in bed, watch the mobile phone, and brush QQ space bored. Although few people are playing QQ space now, however, this kind of habit has never changed until now, and the QQ on the computer is suddenly flashing. I know it's the QQ message sent by Uncle Ding,

In programming, we usually use 10 hexadecimal notation ...... C/C ++ is a high-level language. For example: Int A = 100, B = 99; However, because the representation of data in a computer exists in binary format, sometimes binary can be used to solve the problem more intuitively. However, the binary number is too long. For example, the int type occupies 4 bytes and 32 bits. For example, if the value is 100, the value expressed in the binary number of the int type is: 0000 0000 0000 0000 0110 0100

binary, need to be divided into integers and two parts of the fractional conversion2) When converting integers, the use of the addition of 2 to the remainder method, and the conversion of decimals, with the use of 2 rounding method3) Note the direction of their readingsso we can derive from the above method that the decimal number 168.125 is converted to binary 10101000.001, or the decimal number is converted to a binary number of approximately equal to 10101000.0111. (3) binary conversion to d

C/C ++ Expression of the octal number in 1Expression of the. octal number C/C ++How does one express an octal number in a language? If the number is876,We can conclude that it is not an octal number, because it is impossible to generate7The Arabic numerals above. But if the number is123Yes567, Or12345670Is it

the island, after all, someone else's Japanese level, if not to the heart also can't get through.Or as usual, eating a copy of the hand, discussing what we have been doing in the company recently, an unintentional conversation, he asked me to know what is binary, I said know, he went on to ask, do you know how to use it, I said don't know, don't use binary, still can't write code? Said so much after all, Uncle Ding, still so cool, only blame oneself learn and not fine, so have this article.Bina

OverviewIn fact, the X-decimal algorithm is similar, but if it is in the form of characters, they are a little different. The use of pointers and arrays is different. Here is a demonstration of the octal format of an array of character types into decimal:1#include 2#include 3#include 4 5#define MAX 106 7Initializes the array to octal.8 void9Init (char *octal) {Te

Original article: Is0 a decimal literal or an octal literal? Translation: C ++Is 0 decimal or octal? Translator: justjavac In C ++, is 0 decimal or octal? Even in any number of input systems, 0 has only one value, that is, "zero". The reason for asking this question is purely idle. He recently discussed the topic about data with his friends. He said that eight-d
