cpp integral type: std::integral

c++ integral type:

bool, char, char8_t, char16_t, char32_t, wchar_t, short, int, long, long long

signed

unsigned

std::integral:

template< class T >
concept integral = std::is_integral_v<T>; // (since C++20)

The concept integral<T> is satisfied if and only if T is an integral type.

c++ example

#include <concepts>	// std::integral
#include <iostream>

int main()
{
	std::integral auto x = 9;
	std::cout << x << std::endl;
}

Cheers, cpp/c++ !

const std::string greeting = "Cheers, c++!";

std::cout << greeting << std::endl;

std::cout << greeting.data() << std::endl;
