C++N4910:2022 Standard Working Draft on ISO/IEC 14882(0) sample code compile list

C++コード断片をコンパイルできる形にしようとしている。

直したコードは、できれば整形して見やすくしたい。

残念だったのは、規定値でnamespaceを構造的にしないことかもしれない。

9.8.2.1 General [namespace.def.general] C++N4910:2022 (115) p228.cpp

算譜(source code)

p228.cpp
// C++N4910 Committee Draft, Standard for Programming Language C++

const char * n4910 = "9.8.2.1 General [namespace.def.general] C++N4910:2022 (115) p228.cpp";

#include <iostream>
#include <cstdio>
#include <cstdlib>
#include <cstring>
#include <cassert>
#include <coroutine>
#include <vector>
#include <complex>
#include <map>

using namespace std;

// Example 1
namespace Outer {
int i;
namespace Inner {
void f() {
    i++;    // Outer::i
}
int i;
void g() {
    i++;    // Inner::i
}
}
}
// [Example 2 :
namespace A::inline B::C {
int i2;
}
// The above has the same effect as:
namespace A2 {
inline namespace B2 {
namespace C2 {
int i2;
}
}
}
int main() {
    cout  <<  n4910 << endl;
    return EXIT_SUCCESS;
}
