本文将介绍如何使用C++编写一个程序,实现将二进制数转换为八进制数,以及将八进制数转换为二进制数的功能。
#include <iostream>
#include <string>
#include <cmath>
int binaryToOctal(int binaryNumber) {
int octalNumber = 0, decimalNumber = 0, count = 0;
while(binaryNumber != 0) {
decimalNumber += (binaryNumber % 10) * pow(2, count);
++count;
binaryNumber /= 10;
}
count = 1;
while(decimalNumber != 0) {
octalNumber += (decimalNumber % 8) * count;
decimalNumber /= 8;
count *= 10;
}
return octalNumber;
}
int main() {
int binaryNumber;
std::cout << "Enter a binary number: ";
std::cin >> binaryNumber;
int octalNumber = binaryToOctal(binaryNumber);
std::cout << "Octal number: " << octalNumber << std::endl;
return 0;
}
以上程序实现了将输入的二进制数转换为对应的八进制数,并输出结果。
#include <iostream>
#include <string>
#include <cmath>
int octalToBinary(int octalNumber) {
int binaryNumber = 0, decimalNumber = 0, count = 0;
while(octalNumber != 0) {
decimalNumber += (octalNumber % 10) * pow(8, count);
++count;
octalNumber /= 10;
}
count = 1;
while(decimalNumber != 0) {
binaryNumber += (decimalNumber % 2) * count;
decimalNumber /= 2;
count *= 10;
}
return binaryNumber;
}
int main() {
int octalNumber;
std::cout << "Enter an octal number: ";
std::cin >> octalNumber;
int binaryNumber = octalToBinary(octalNumber);
std::cout << "Binary number: " << binaryNumber << std::endl;
return 0;
}
以上程序实现了将输入的八进制数转换为对应的二进制数,并输出结果。
以上两个程序可作为一个辅助工具,帮助开发人员在需要进行二进制与八进制数之间转换时,提供方便快捷的解决方案。
