Values in C++

C++ has various value types including strings, integers, floats, booleans, etc. Here are a few basic examples.

#include <iostream>
#include <string>

int main() {
    // Strings, which can be added together with +.
    std::cout << "cpp" + "lang" << std::endl;

    // Integers and floats.
    std::cout << "1+1 = " << 1+1 << std::endl;
    std::cout << "7.0/3.0 = " << 7.0/3.0 << std::endl;

    // Booleans, with boolean operators as you'd expect.
    std::cout << std::boolalpha;
    std::cout << (true && false) << std::endl;
    std::cout << (true || false) << std::endl;
    std::cout << (!true) << std::endl;

    return 0;
}

To run the program, save it as values.cpp, compile it, and then execute the resulting binary:

$ g++ -std=c++11 values.cpp -o values
$ ./values
cpplang
1+1 = 2
7.0/3.0 = 2.33333
false
true
false

In this C++ version:

1. We include the necessary headers: <iostream> for input/output operations and <string> for string manipulation.

2. The main() function is the entry point of the program.

3. We use std::cout for output instead of fmt.Println.

4. String concatenation is done with the + operator, similar to the original.

5. For boolean output, we use std::boolalpha to print true and false instead of 1 and 0.

6. The program returns 0 at the end to indicate successful execution.

Note that C++ uses << for stream insertion and std::endl for line breaks. The syntax for arithmetic operations and boolean logic remains the same as in the original example.
