1つの機能が別の機能を終了したらどうすればよいですか？

Question

私には問題があります。私は、定期的な電卓と形状の面積と周囲のファインダーを作ろうとしています。それは組み合わせです。私はShapeのAreaとPerimeter Finderで始まらなかった。これは私のmain.cppです。

#include <iostream> 
#include <string> 
#include "AAPO.h" // Its a Header File. 

using namespace std; 

void Calculators_Operation(); 

int main() 
{ 
    string opera; 
    cout << "Do you want Arithmetic Calculator or Area and Perimeter Calculator" 
    << endl; 

    cin >> opera; 
    if (opera == "Arithmetic Calculator" or "arithmetic calculator" or "AC") 
    { 
     Calculators_Operation(); 
    } 
    return 0; 
} 

これは私の操作の選択です。

#include <iostream> 
#include <string> 
#include "Arithmetic Chooser.h" 

using namespace std; 

void Calculators_Addition(); 
void Calculators_Subtraction(); 
void Calculators_Multiplication(); 
void Calculators_Division(); 

void Calculators_Operation() 
{ 
    string answera; 
    cout << "What Operation do you Want?" << endl; 
    cin >> answera; 
    if (answera == "Addition" or "addition" or "+"); 
    { 
     Calculators_Addition(); 
    }; 
    if (answera == "Subtraction" or "subtraction" or "-"); 
    { 
     Calculators_Subtraction(); 
    }; 
    if (answera == "Multiplication" or "multiplication" or "*" or "x" or "X") 
    { 
     Calculators_Multiplication(); 
    }; 
    if (answera == "Division" or "division" or "/") 
    { 
     Calculators_Division(); 
    }; 
    return; 
} 

これは私のAAPO.hです。

#define AAPO_H_INCLUDED 

void Calculators_Operation(); 

#endif // AAPO_H_INCLUDED

今問題は、加算が終了すると減算が開始されることです。減算後、乗算。乗算後、除算。その後、プログラムは終了します。ごめんなさい。そのちょうど私はプログラミングに新しいです（1ヶ月のように）。

Answer 1

あり改善するための多くのものは、（それらのいくつかはすでにコメントで述べた）ですが、あなたの質問に正確な答えは次のとおりです、あなたはCalculators_Operation（）関数本体であなたのif文の行の後にセミコロンいる

• if文が役に立たず、あなたの "操作"関数が毎回呼び出されています（あなたがすでに気づいたもの）。
• あなたは（answera == "addition"または "+"）を使用すると、誤ったやり方で "or"演算子を使用しますが、基本的には（（answera == "addition" or "+"））真

EDITを（hereを参照してください）： あなたの関数Calculators_Operationに変更することができる。

void Calculators_Operation() 
{ 
    string answera; 
    cout << "What Operation do you Want?" << endl; 
    cin >> answera; 

    if (answera == "Addition" || answera == "addition" || answera == "+") 
    { 
     Calculators_Addition(); 
    } 
    else if (answera == "Subtraction" || answera == "subtraction" || answera == "-") 
    { 
     Calculators_Subtraction(); 
    } 
    else if (answera == "Multiplication" || answera == "multiplication" || answera == "*" || answera == "x" || answera == "X") 
    { 
     Calculators_Multiplication(); 
    } 
    else if (answera == "Division" || answera == "division" || answera == "/") 
    { 
     Calculators_Division(); 
    } else { 
    cout << "Unknown operation entered!" << endl; 
    } 
}
