このコードを最適化するにはどうしたらよいですか？私はvectorをcoutに使用できますか？

Question

string str; 

    str = "  General Knowledge Test  "; 

    cout << string(39, ' ') << string (37 , '-') << "\n"; 

    cout << string(39, ' ') << "|" << str<< "|\n "; 

    cout << string(38, ' ') << string (37 , '-') << "\n"; 

    cout << string(39, ' ') << "|"<< string (35 , ' ') << "|"<< "\n"; 

    cout << string(39, ' ') << "|" << " > Pentru a continua apasa 'k'  |\n "; 

    cout << string(38, ' ') << "|" << " > Pentru ajutor apasa 'a'   |\n "; 

    cout << string(38, ' ') << "|" << " > Pentru raspunsuri apasa 'r'  |\n "; 

    cout << string(38, ' ') << "|" << " > Pentru high score apasa 'h'  |\n "; 

    cout << string(38, ' ') << "|" << " > Pentru a iesi apasa 'q'   |\n "; 

    cout << string(38, ' ') << "|"<< string (35 , ' ') << "|"<< "\n"; 

    cout << string(39, ' ') << string (37 , '-') << "\n\n";

あなたは、静的出力の可読性と保守性を向上させるためにリテラル生の文字列を使用することができます。

#include <iostream> 
#include <string> 


int main(){ 
    std::string str = 
R"(          ------------------------------------- 
             |  General Knowledge Test  | 
             ------------------------------------- 
             |         | 
             | > Pentru a continua apasa 'k'  | 
             | > Pentru ajutor apasa 'a'   | 
             | > Pentru raspunsuri apasa 'r'  | 
             | > Pentru high score apasa 'h'  | 
             | > Pentru a iesi apasa 'q'   | 
             |         | 
             -------------------------------------)"; 
    std::cout << str; 
} 

live demoを参照してください。もちろん

あなたもstd::vector<std::string>を使用することができます（それは必ずしも最適ではありません）：

#include <iostream> 
#include <iomanip> 
#include <string> 
#include <vector> 

int main(){ 
    std::vector<std::string> strs { 
"-------------------------------------", 
"|  General Knowledge Test  |", 
"-------------------------------------", 
"|         |", 
"| > Pentru a continua apasa 'k'  |", 
"| > Pentru ajutor apasa 'a'   |", 
"| > Pentru raspunsuri apasa 'r'  |", 
"| > Pentru high score apasa 'h'  |", 
"| > Pentru a iesi apasa 'q'   |", 
"|         |", 
"-------------------------------------" 
}; 
    for(auto str : strs) { 
     std::cout << std::setw(70) << std::right << str << '\n'; 
    } 
} 

は、ここで再びlive demoです。
