#include <iostream>using namespace std;void main(){    int a = 010, b = 10, c = 0X10;//以0开头的数是八进制数，0X开头的是16进制数.    //以十进制显示数据;    cout << "DEC：" << endl;    //cout << dec;//要不要都可以，默认输出时以十进制输出;    cout << "a= " << a<<endl;    cout << "b = " << b<<endl;    cout << "c = " << c<<endl;    cout << endl;    cout << "OCT" << endl;    cout << oct;             //指定八进制输出    cout << "a= " << a << endl;    cout << "b = " << b << endl;    cout << "c = " << c << endl;    cout << endl;    cout << "HEX" << endl;    cout << hex;           //指定十六进制输出    cout << "a= " << a << endl;    cout << "b = " << b << endl;    cout << "c = " << c << endl;    //八，十和十六进制数混合运算并输出    cout << "a+b+c=";    cout << dec;    cout << a + b + c << endl;    //测试八，十和十六进制输入以及输出    cout << "DEC:a="; cin >>dec>> a;    cout << "OCT:b="; cin >>oct>>b;    cout << "HEX:a="; cin >>hex>>c;      //全部指定为八进制输出    cout <<oct<< "a=" << a << endl;    cout <<oct<< "b=" << b << endl;    cout <<oct<< "c=" << c << endl;}

这是写的一个小的代码程序，有什么不懂得欢迎咨询，大家一起讨论，共同进步。
