Utxcpp Fast Guide. Utxcpp Fast Tutorial.

Include Utxcpp Headers

You just use one header to include utxcpp library:

#include <utxcpp/core.hpp>

1. utx::print and utx::printnl: Print Something Out

utx::print and utx::printnl are convenient way to print something out, which do not need you to worry about data types.

utx::print will add a newline at the end, but utx::printnl does not.

Example

#include <utxcpp/core.hpp>

int main() {
	utx::print(2, '+', 3, "is", 2+3);
	utx::printnl(2, '+', 3, "is", 2+3);
	utx::print(2, '+', 3, "is", 2+3);
	utx::printnl(2, '+', 3, "is", 2+3);
}

The result will be:

2 + 3 is 5
2 + 3 is 5 2 + 3 is 5
2 + 3 is 5

Another Example

#include <string>
#include <utxcpp/core.hpp>

int main() {
	utx::print("Hello, No.", 3, "World!");
	std::string name;
	utx::printnl("Please Input Your Name:");
	std::getline(std::cin, name);
	utx::print("\nYour name is", name);
}

Possible Result:

Hello, No. 3 World!
Please Input Your Name: Boost Software

Your name is Boost Software

Hello, No. 3 World!
Please Input Your Name: ^C

Hello, No. 3 World!
Please Input Your Name: ^D
Your name is

2. Utxcpp Types for smoothly programming

Utxcpp provides the basic data types for convenient smoothly programming.

Basic Types

Example

utx::i32 a = 9;
utx::i32 b = -42;
utx::u8 c = 255;
utx::u64 d = 337;

utx::print(a, b, (utx::u16)c, d);

utx::print(utx::i8_max, utx::i8_min, utx::u64_max, utx::i32_max, utx::i32_min);

Ext Integral Types

Example

utx::ext::u24 a = 97; // 24 bit unsigned integral type.
utx::print(a);

utx::ext::u24 b = 0xA475FF;
utx::print(b);

utx::ext::i56 c = -100; // 56 bit signed integral type.
utx::print(c);

Create Your Own Ext Integral Types

Example

using my_i59 = utx::ext::ext_integral_type<utx::i64, 59>; // 59 bits
using my_u57 = utx::ext::ext_integral_type<utx::u64, 57>; // 57 bits

my_i59 a = 332;
my_u57 b = 233;
utx::print(a, b); // 332 233

// 59 59 57 57
utx::print(a.bits(), my_i59::bits(), b.bits(), my_u57::bits());
