C++ 멀티 라인 문자열이 예상대로 작동하지 않습니다.

Question

Windows에서 응용 프로그램의 배너를 만들려고합니다.

// C Libraries: 
#include <string> 
#include <iostream> 
#include <algorithm> 

// Namespaces: 
using namespace std; 

const char *BANNER[] = R"BANNER(
      .-') _        .-') 
      ( OO))       (OO). 
,--. ,--./ '._ ,-.-') ,--.  ,-.-') (_)---\_) 
| | | | |'--...__)| |OO) | |.-') | |OO)/ _ | 
| | | .-')'--. .--'| | \ | | OO) | | \\ :` `. 
| |_|(OO) | | | |(_/ | |`-' | | |(_/ '..`''.) 
| | | `-'/| | ,| |_.'(| '---.',| |_.'.-._) \ 
(' '-'(_.-' | | (_| | |  |(_| | \  /
`-----'  `--' `--' `------' `--' `-----')BANNER"; 

char* getCmdOption(char ** begin, char ** end, const std::string & option) 
{ 
    char ** itr = find(begin, end, option); 
    if (itr != end && ++itr != end) 
    { 
     return *itr; 
    } 
    return 0; 
} 

bool cmdOptionExists(char** begin, char** end, const std::string& option) 
{ 
    return find(begin, end, option) != end; 
} 

int main(int argc, char * argv[]) 
{ 
    printf("%s\n", BANNER); 

    if(cmdOptionExists(argv, argv+argc, "-h")) 
    { 
     cout << "Help Menu"; 
    } 


    if (cmdOptionExists(argv, argv + argc, "-a")) 
    { 
     cout << "Adobe"; 
    } 

    return 0; 
} 

난 당신이 여러 줄 문자열을 생성하는 구문 R"(<string here>)"; 또는 R"BANNER(<string here>)BANNER";를 사용할 수있는 다중 스레드 및 여러 웹 사이트에서 읽었습니다. 그러나 나는 다음과 같은 오류가 얻을이 코드를 컴파일에 도착했을 때 :

내가 여러 줄 문자열을 만들 수없는 지점에 잘못하고 있어요 무엇을?

나는 또한 시도했다 : cout << BANNER과 같은 출력을 얻을. 내게는 to many characters in constant 오류가 의미가 없습니다. 큰 광경을 본 적이 있기 때문에, 예를 들어 here을 참조하십시오.

Answer 1

문제는, 또한

const char *BANNER = R"BANNER(

해야

const char *BANNER[] = R"BANNER(

[]을 넣어 C++ 11 이상을 사용하는 것입니다. g ++에서 나를 위해 -std=c++11으로 작동합니다.
