でエグゼクティブオブジェクトを作成すると、「「エグゼクティブ」の暗黙的に削除されたデフォルトコンストラクターへの呼び出しというエラーが表示されますmain.cpp
。解決方法がわかりません。
これはmain.cpp
次のとおりです。
#include <iostream>
#include <fstream>
#include "Executive.h"
using namespace std;
int main(int argc, const char * argv[])
{
Executive ex;
ifstream num("Lab01Polynomial.txt");
ifstream com("Lab01Directives");
ex.readFiles(num ,com);
num.close();
com.close();
return 0;
}
これはExecutive.h
次のとおりです。
#ifndef lab1_eecs_Executive_h
#define lab1_eecs_Executive_h
#include <fstream>
#include "Polynomial.h"
class Executive{
private:
static const int MAX_DEGREE = 20;

double coeff[MAX_DEGREE];
Polynomial p[MAX_NUM_POLYNOMIALS];
public:
void readFiles(std::istream &inpNumber, std::istream &inpInstructions);
};
#endif
これはExecutive.cpp
次のとおりです。
#include "Executive.h"
#include <fstream>
#include <iostream>
#include "Polynomial.h"
using namespace std;

次のとおりです。
