Question

嗨我有以下代码，我想通过for循环创建所有可能的变量来查看字符串列表，我在理解如何打印字符串时遇到问题，包括所有＆＃34;＆＃34;而且，像这样的东西：

 "","""polo-M-GRE""","polo-M-GRE","Products","Unit",0,"","","","Size","Medium",0,0.0,0.0,0.0,"","","","","",""
"","","","","","","","","","Colour","TTR",0,0.0,0.0,0.0,"","","","","",""

欢迎任何帮助，谢谢。

#include <cstdlib>
#include <iostream>
#include <string>
using namespace std;

/*
 * 
 */
int main(int argc, char** argv) {

    string size_attr[] = {"Extra Small","Small","Medium","Large","Extra Large"};
    string size_abv[]={"XS","S","M","L","XL"};
    string color_attr[]={"Red","Green","Blue","Black","White"};
    string color_abv[]={"RED","GRE","BLU","BLA","WHI"};
    for (int i = 0; i <= (sizeof (size_attr) / sizeof (*size_attr)); i++) {
        for (int y = 0; y <= 4; y++) {
            cout << "\"\""",""""polo-M-RED""","polo-M-RED","Products","Unit",0,"","","","Size","Medium",0,0.0,0.0,0.0,"","","","","",""
"","","","","","","","","","Colour","Red",0,0.0,0.0,0.0,"","","","","",""<< endl;
        }
    }
       return 0;
}

我认为您要输出size_attr[]和color_attr[]。查找最后cout<<，即转义字符。

#include <cstdlib>
#include <iostream>
#include <string>
using namespace std;
int main(int argc, char** argv) {

    string size_attr[] = {"Extra Small","Small","Medium","Large","Extra Large"};
    string size_abv[]={"XS","S","M","L","XL"};
    string color_attr[]={"Red","Green","Blue","Black","White"};
    string color_abv[]={"RED","GRE","BLU","BLA","WHI"};

    //"","""polo-M-GRE""","polo-M-GRE","Products","Unit",0,"","","","Size","Medium",0,0.0,0.0,0.0,"","","","","","" "","","","","","","","","","Colour","TTR",0,0.0,0.0,0.0,"","","","","",""
    for (int i = 0; i < (sizeof (size_attr) / sizeof (*size_attr)); i++)
    {
        for (int y = 0; y <= 4; y++)
        {
//          cout <<"\"\",\"\"\"polo-M-RED\"\"\",\"polo-M-RED\",\"Products\",\"Unit\",0,\"\",\"\",\"\",\"Size\",\"Medium\",0,0.0,0.0,0.0,\"\",\"\",\"\",\"\",\"\",\"\" \"\",\"\",\"\",\"\",\"\",\"\",\"\",\"\",\"\",\"Colour\",\"Red\",0,0.0,0.0,0.0,\"\",\"\",\"\",\"\",\"\",\"\""<< endl;
            cout <<"\"\",\"\"\"polo-M-RED\"\"\",\"polo-M-RED\",\"Products\",\"Unit\",0,\"\",\"\",\"\","<<size_attr[i]<<",\"Medium\",0,0.0,0.0,0.0,\"\",\"\",\"\",\"\",\"\",\"\" \"\",\"\",\"\",\"\",\"\",\"\",\"\",\"\",\"\",\"Colour\",\""<<color_attr[y]<<"\",0,0.0,0.0,0.0,\"\",\"\",\"\",\"\",\"\",\"\""<<endl;
        }
    }

    //Output escape characters
    cout<<" \" ' < > , . ~ ! @ # $ % ^ & * ( ) _ + - = [ ] { } : ; ? / | \\"<<endl;
    return 0;
}

结果：

Printed Screen Outputs - Console

转义c ++和for循环中的字符
