0xC0000005:访问冲突写入位置0xCDCDCDCD动态分配错误

根据PaulMcKenzie的建议，这就是它的滚动方式。使用模板对您来说可能有点多，但如果可以的话......否则，请分别创建名称和评分容器。但是，您需要维护重复的代码。

这个想法是将你所有的东西都保持某种顺序。请注意，现在内存管理在container中处理。

我放弃了处理std::cin和分数，但你应该更容易编码这些东西，而不会有很多绒毛。在那个，没有std::cin的情况下开发，这是浪费时间。你应该写，这样你就可以编辑和运行。

另外，摆脱using namespace std;的习惯 从长远来看，它会得到回报。

#define DEV
template<typename T>
struct container {
size_t size;
T* ar;
container(size_t size) :size(size) {
ar = new T[size];
}
~container() { delete[]ar; }
T& operator [](size_t pos) { return ar[pos]; }
};
using names_c = container<std::string>;
using scores_c = container<double>;
size_t inputData(names_c& names, scores_c& scores);
int main() {
container<std::string> names(2);
container<double> scoreSet(2);
auto size = inputData(names, scoreSet);
for (int i = 0; i < size; i++) {
std::cout << names[i] << endl;
}
}
size_t inputData(names_c& names, scores_c& scores) {
#ifdef DEV
size_t numStudents = 2;
names[0] = "tom";
names[1] = "mary";
#else
//do your std::cin stuff
#endif
return names.size;
}

我不打算去那里，但是。您可以扩展该概念，以便在容器中具有容器。更容易知道什么分数与哪个学生在一起。

struct student_type {
using scores_c = container<double>;
std::string name;
scores_c scores;
};
using student_c = container<student_type>;

我已经接受了您的代码，并对其进行了修改以使其正常工作。我已经删除了您的评论，并在我更改的行上放置了评论。

#include <iostream>
#include <string>
using namespace std;
int inputData( string *&names, double **&scores );
int main() {
string *names = nullptr;
double **scores = nullptr; // Changed to double ** so it's "2D"
// double **scoreSet = &score; // removed, this was unneeded and probably causing problems
int size = 0;
size = inputData( names, scores );
for ( int i = 0; i < size; i++ ) {
cout << *( names + i ) << endl;
}
}
int inputData( string *&names, double **&scoreSet ) {
int numStudents = 0;
cout << "How many students do you have in the system? ";
cin >> numStudents;
while ( numStudents <= 0 ) {
cout << "Invalid number of students. Please enter number of students: ";
cin >> numStudents;
}
names = new string[numStudents];
scoreSet = new double*[numStudents]; // allocate an array of pointers
// cin.ignore( 10000, 'n' ); // Removed from here, placed inside loop
for ( int i = 0; i < numStudents; i++ ) {
cin.ignore( 10000, 'n' ); // placed here so that it always clears before getting the name
int numTests = 0;
cout << "Enter the student's name: ";
getline( cin, names[i] );
cout << "Enter how many tests " << names[i] << " took: "; // simplified
cin >> numTests;
scoreSet[i] = new double[numTests]; // simpliefied left hand side
//cin.ignore( 10000, 'n' ); // not needed
for ( int j = 0; j < numTests; j++ ) {
cout << "Enter grade #" << j + 1 << ": ";
cin >> scoreSet[i][j]; // simplified
}
}
return numStudents;
}
