std::isgraph

namespace std {
  int isgraph(int ch);
}

概要

ch が図表文字（空白を除く表示文字）かどうかを判定する（判定はロケールの影響を受ける）。

戻り値

ch が図表文字と判定されれば非ゼロを、そうでなければゼロを返す。

例

#include <cctype>
#include <iostream>

int main() {
    std::cout << "isgraph('A') = " << std::isgraph('A') << std::endl
              << "isgraph('a') = " << std::isgraph('a') << std::endl
              << "isgraph('Z') = " << std::isgraph('Z') << std::endl
              << "isgraph('z') = " << std::isgraph('z') << std::endl
              << "isgraph('3') = " << std::isgraph('3') << std::endl
              << "isgraph('.') = " << std::isgraph('.') << std::endl
              << "isgraph(' ') = " << std::isgraph(' ') << std::endl
              << "isgraph('\\n') = " << std::isgraph('\n') << std::endl
              << "isgraph('0x0f') = " << std::isgraph(15) << std::endl;
}
