構造体の配列 - データを引っ張らない関数

Question

私はBscCSを勉強していますので、プログラミングの概念に精通していますが、構造体と構造体の配列についているようです。

並列配列を構造体の配列に変換する必要があります。私はこれをしましたが、何らかの理由で情報が適切に関数に送られず、プログラムがクラッシュしています。

私が紛失しているものがある場合は、私が間違っている場所を特定するのに役立つでしょうか？私は答えのための正確なコード、ちょうどいくつかの指導を必要としません。コードは次のとおりです。

#define SIZE 3 
struct Employee { 

string firstName[SIZE]; 
string lastName[SIZE]; 
int id[SIZE]; 
int hoursWorked[SIZE]; 
int payRate[SIZE]; 
int stat[SIZE]; 

}; 

//Functions 
int menu(); 
void printReport(Employee & employees); 
void search(Employee & employees); 
void calculatePay(Employee & employees); 
void orderByLastName(Employee & employees); 
void orderByid(Employee & employees);

void printInactive(Employee & employees); 

//Display Main Menu

あなたのプログラムを実行しましたが、コンパイラが意図せずにコンパイルをやめようとする前に、20を超えるエラーが発生しました。それらのすべては、cout、cin、string、およびsetwを使用してコード行に接続されています。これを修正するには、stdネームスペースでこれらのキーワードを使用する必要があります。また、iostreamヘッダーファイル（#include <iostream>）を含める必要があります。これらすべてのキーワードの前にstd::と書くことができます（つまり、std::cout）、またはプリプロセッサー（using namespace std;）で名前空間を宣言することができます。また、std::setwの場合は、iomanipヘッダーファイル（#include <iomanip>）を含める必要があります。その後、メニュー関数には引用符がなく、メイン関数の最後にはカッコがありません。 （宣言に構造体メンバのサイズを初期化するのにもいくつかの問題がありますが、私はそれをあなたに任せます）。
