こんにちは、私は C++ が初めてで、dev-c++ で C++ コードの構造をテストしています。しかし、コンパイルしてエラーを出すことはありません。dev-c++ のプリプロセッサ ディレクティブで .h 拡張子を使用するとうまく機能します。だから私はそうは思わない.h拡張子の問題を抱えている
#include<iostream.h>
#include<conio.h>
#include<iomanip.h>
struct car
{
const int MAX=10;
char model[MAX];
char spare_part[MAX];
float cost;
}
int main()
{
car BMW ;
BMW.model[MAX]="SLR-8 S";
BMW.spare_part[MAX]="SILENCER";
BMW.cost=175.56F;
cout << setw(50) << "\n\n WELCOME TO SHOWROOM" << endl << endl;
cout << "CAR MODEL: " << BMW.model[MAX] << endl;
cout << "SPARE PART: " << BMW.spare_part[MAX] << endl;
cout << "COST OF PRODUCT: " << BMW.cost[MAX] << endl;
return 0;
}
コンパイラ ログは次のとおりです。
