Write a function that converts a decimal number to its corresponding octal number. The program reads in a decimal number, calls the function to implement the number conversion, the output corresponding octal. Sample Input9274Sample Output22072Sample Input -Sample Output22Code one;#include #include using namespace Std;int main (){int n;CIN >> N;printf ("%o\n", N);
, take the IP address of "61.175.232.30" as an example, the IP address is converted to a number string method as follows: First convert "61.175.232.30" to hexadecimal "3d.af.e8.1e", then remove the decimal point and change to "3dafe81e", Finally converts this hexadecimal number to decimal "1034938398", then "61.175.232.30" becomes "1034938398".

This article describes how C + + implements a hexadecimal string conversion to a decimal integer. Share to everyone for your reference. The implementation method is as follows:
* * Converts a string of hexadecimal digits (including an optional prefix of 0x or 0X) to an integral value equivalent to it/* #include

Recently, some tasks related to IP address translation have been encountered due to the working relationship. Here is a summary:
1. about converting unsigned int to dot decimal:
(1) first define a struct in_addr myaddr; such a struct, in_addr is generally a 32-bit unsigned long, where every 8 bits represent a value in an IP address bit ..
(2) myaddr = p_net_para-> ip_address; the unsigned int used in the program is paid to myaddr.
(3), inet_ntoa (

Stack is undoubtedly the best choice and the best place to reflect the advantages of stack for the conversion between hexadecimal systems in digital systems.
The following is a simple conversion between decimal numbers to 2, 8, and 16 in C:(Of course, CLR also has a simpler method, that isConvert.Tostring(IntValue,IntTobase), value is the
