C++ 第40课转进制

#include <iostream>
#include <string>
using namespace std;
int main() {
    /*string a;
    int p = 1;
    int s = 0;
    cout<<"请输入一个二进制数:";
    cin>>a;
    for(int i = a.length()-1;i>=0;i--){
        int x = a[i]-'0';
        s += x*p;
        p *= 2;
    }
    cout<<s<<endl;
    */
    int a[10],n,i; 
	cout<<"请输入一个十进制数:";     
    cin>>n;    
    for(i=0;n>0;i++){    
        a[i] = n%2;    
        n = n/2;  
    }     
    for(i=i-1;i>=0;i--){    
        cout<<a[i];    
    }
    return 0;
}
