C++ 存储cout的值

我有以下代码

#include <iostream>
#include <math.h>
#include <string>
#include <sstream>
using namespace std;
int main() {
int value
cout << "Input your number: " << endl;
cin >> value;
string s = to_string(value);
const int count = s.length();
int position = count;
for (int i = 1; i < count + 1; i++)
{
    int pwr = pow(10, position - 1);
    cout << ((value / pwr) + position) % 10;
    position--;
    value = value % pwr;
}

它能够输出我想要的值，但是有一个运行时故障2-变量“val”周围的堆栈已损坏。为什么会这样？

您可以使用类似vector的STL容器

#include <iostream>
#include <math.h>
#include <string>
#include <sstream>
#include <vector>

using namespace std;
int main() {
  int value;
  cout << "Input your number: " << endl;
  cin >> value;
  string s = to_string(value);
  const int count = s.length();
  int position = count;

  vector<int> outputs;

  for (int i = 1; i < count + 1; i++)
  {
    int pwr = pow(10, position - 1);
    outputs.push_back(((value / pwr) + position) % 10);
    cout << outputs.back();

    position--;
    value = value % pwr;
  }

  cout << endl;

  // iterate through the vector later
  for (auto i : outputs)
  {
    cout << i;
  }

  cin.get();
}

存储到vector，然后打印它

这并不难。因为你不知道结果的大小或数量，所以使用向量是很有用的

只需创建一个向量并返回您的结果，就可以不使用我们在@Wing Hang Khoo课程中没有学习过的代码。如何使用for循环将xx的值存储到变量中？我认为你应该放弃C++并接受jQuery。它内置了将值存储到变量中的for。谢谢，但不能使用我们在课堂上没有学过的代码。

#include <iostream>
#include <math.h>
#include <string>
#include <sstream>
#include <vector>

using namespace std;
int main() {
  int value;
  cout << "Input your number: " << endl;
  cin >> value;
  string s = to_string(value);
  const int count = s.length();
  int position = count;

  vector<int> outputs;

  for (int i = 1; i < count + 1; i++)
  {
    int pwr = pow(10, position - 1);
    outputs.push_back(((value / pwr) + position) % 10);
    cout << outputs.back();

    position--;
    value = value % pwr;
  }

  cout << endl;

  // iterate through the vector later
  for (auto i : outputs)
  {
    cout << i;
  }

  cin.get();
}

#include <iostream>
#include <math.h>
#include <string>
#include <sstream>
#include<vector>
#include<iterator>
#include<algorithm>

using namespace std;

int main() {
    int value;
    vector<int> results;
    cout << "Input your number: " << endl;
    cin >> value;
    string s = to_string(value);
    const int count = s.length();
    int position = count;
    for (int i = 1; i < count + 1; i++)
    {
        int pwr = pow(10, position - 1);
        auto val = ((value / pwr) + position) % 10;
        results.push_back(val);
        position--;
        value = value % pwr;
    }
    copy(results.begin(),results.end(),ostream_iterator<int>(cout," "));

}
