怎么建立文件夹

如何建立文件夹
请问如何在一个由键盘输入名称的文件夹下建立一个子文件夹


[解决办法]
char *path = new char(10);
cin> > path;
_mkdir(path);
[解决办法]
// crt_makedir.c

#include <direct.h>
#include <stdlib.h>
#include <stdio.h>

int main( void )
{
if( _mkdir( "\\testtmp " ) == 0 )
{
printf( "Directory '\\testtmp ' was successfully created\n " );
system( "dir \\testtmp " );
if( _rmdir( "\\testtmp " ) == 0 )
printf( "Directory '\\testtmp ' was successfully removed\n " );
else
printf( "Problem removing directory '\\testtmp '\n " );
}
else
printf( "Problem creating directory '\\testtmp '\n " );
}
