定義於標頭檔案 <experimental/filesystem>
path operator/( const path& lhs, const path& rhs );		(檔案系統 TS)

連線兩個路徑。實際返回 path(lhs) /= rhs。

引數

lhs, rhs

要連線的路徑

返回值

路徑連線的結果。

異常

noexcept 規範：

示例

執行此程式碼

#include <experimental/filesystem>
#include <iostream>
namespace fs = std::experimental::filesystem;
 
int main()
{
    fs::path p1 = "C:Users";
    std::cout << "\"C:\" / \"Users\" == " << p1 << '\n';
    fs::path p2 = "batman";
    fs::path p3 = p1 / p2; // inserts fs::path::preferred_separator, '\' on Windows
    std::cout << "\"C:\" / \"Users\" / \"batman\" == " << p3 << '\n';
}

輸出

"C:" / "Users" == "C:Users"
"C:" / "Users" / "batman" == "C:Users\batman"
