学习C++过程中遇到的问题

Question

求解

#include<iostream>

using namespace std;

int main(void){
    int n,m,count=0;
    cin >> n;

    m=n;
    for(int i=0;;i++){
        m/=2;
        count++;
        if(m==0){
            break;
        }
        
    }
    int x=0;
    
    while(true){
        m=n%2;
        n/=2;
        x++;
        if(n!=0&&m==1){
            cout << "2(" << count-1-x << ")+" ;
        }
        if(n==0){
            if(m==1){
                cout << "2(0)" ;
                break;
            }
            else
                break;
        }   
    }
    return 0;
}

不知道错在哪里

Answer 1

#include <iostream>
#include <string>
using namespace std;

string toPowerOfTwo(int n) {
    string res = "";
    int power = 0;
    while (n > 0) {
        if (n % 2 == 1) {
            if (!res.empty()) {
                res = "+" + res;
            }
            res = "2(" + to_string(power) + ")" + res;
        }
        n /= 2;
        power++;
    }
    return res;
}

int main() {
    int n;
    cin >> n;
    cout << toPowerOfTwo(n) << endl;
    return 0;
}
