C++题目：整数内码

Answer 1

#include<iostream>
using namespace std;
int main()
{
    int i,j,n,num[50];
       
    bool exi = false;
    for(i=0;i<50;i++){
        if ( !(cin>>num[i]) )
        {
            break;
        }else{
            int code[32]={0};
            j=0;
            int b = num[i];
            if(b<0){
                b = 2147483648 - b;
                code[31] = 1;
            }
               
            while(b){
                if (b%2)
                {
                    code[j++] = 1;
                }else{
                    j++;
                }
                b /=2;
            }
            for (n=31;n>=0;n--)
            {
                cout<<code[n];
            }
            cout<<"  "<<num[i]<<endl;
        }
    }
