在C ++中的当前目录内创建多个文件夹

Question

I want to make some folders using a loop in current directory in c++. I have made a code but getting the following error.

cannot convert 'std::string {aka std::basic_string}' to 'const char*' for argument '1' to 'void CreateFolder(const char*)'

My code is:

 #include<iostream>
 #include<cstdio>
 #include<cstring>
 #include <windows.h>
 #include <cstdio>
 #include<cstdlib>
 #include<fstream>
 #include <sstream>
 using namespace std;

#define total 28

std::string to_string(int i) {
   std::stringstream s;
   s << i;
   return s.str();
}


void CreateFolder(const char * path)
{
    if(!CreateDirectory(path ,NULL))
    {
        return;
    }
}


main()
{
    string folder_name;
    string suffix = ".\\"; // for current directory

     for(int i=0;i<=total;i++)
    {
        folder_name=suffix+to_string(i);
        CreateFolder(folder_name);

    }

} 

How will I create those folders named 0,1... to 28?

You can not directly pass a std::string as char* . By using c_str() function you can retrieve the raw char* from std::string .

//std::string -> const char*
CreateFolder(folder_name.c_str());
