c++ - 将十六进制值存储在字符串 C++ 中

Question

例如:

char str[] = {0x1B, 0x54, 0x32, 0xFE, 0x88, 0x10, 0x34, 0x6F, 0x54};

但这是C风格。那么我如何在不使用 C 函数的情况下对 std::string 做同样的事情呢？

Answer 1

So how can i do same with std::string and without using C functions?

试试这个:

std::string str{0x1B, 0x54, 0x32, 0xFE, 0x88, 0x10, 0x34, 0x6F, 0x54};

或者这个:

using namespace std::literals::string_literals;

auto str = "\x1B5432FE8810346F54"s;

或者这个:

std::string str = "\x1B5432FE8810346F54";
