Defined in header <filesystem>
path operator/( const path& lhs, const path& rhs );		(since C++17)

Concatenates two path components using the preferred directory separator if appropriate (see operator/= for details).

Effectively returns path(lhs) /= rhs.

Parameters

lhs, rhs

-

paths to concatenate

Return value

The result of path concatenation.

Example

Run this code

#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;
int main() {
    fs::path p = "C:";
    std::cout << "\"C:\" / \"Users\" / \"batman\" == "
              << p / "Users" / "batman" << '\n';
}

Possible output:

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