How to make strings faster - Most optimized

#include <iostream>
#include <string>

static uint32_t s_AllocCount = 0;

void* operator new(size_t size)
{
    s_AllocCount++;
    std::cout << "Allocating " << size << " bytes\n";

    return malloc(size);
}

void PrintName(std::string_view name) // No need for const reference
{
    std::cout << name << std::endl;
}

int main()
{
    const char* name = "Yan Chernikov"; // Changed from string to const char*

#if 0
    std::string firstName = name.substr(0, 3);
    std::string lastName = name.substr(4, 9);
#else
    std::string_view firstName(name, 3); // Removed c_str()
    std::string_view lastName(name + 4, 9); // Removed c_str()
#endif

    PrintName("Cherno"); // Also no allocation since PrintName is std::string_view
                        // Changing back to std::string will give an allocation
    PrintName(firstName);
    PrintName(lastName);

    std::cout << s_AllocCount << " allocations" << std::endl;
    std::cin.get();
}
