在C++中将类向量导出为.dat

void exportToDat(const VectorClass& vec) {
    ofstream file("data.dat", ios::binary);
    if (!file) {
        cout << "Failed to open file!" << endl;
        return;
    }
    // 写入数据到文件
    // ...
}

file.write(reinterpret_cast<const char*>(vec.data), sizeof(vec.data));

file.close();

#include <iostream>
#include <fstream>

using namespace std;

class VectorClass {
public:
    int data[3] = {1, 2, 3};
};

void exportToDat(const VectorClass& vec) {
    ofstream file("data.dat", ios::binary);
    if (!file) {
        cout << "Failed to open file!" << endl;
        return;
    }
    file.write(reinterpret_cast<const char*>(vec.data), sizeof(vec.data));
    file.close();
}

int main() {
    VectorClass vec;
    exportToDat(vec);
    return 0;
}
