How do I avoid format string vulnerabilities with std::format?

Format string vulnerabilities can lead to serious security issues in applications. C++ offers the `std::format` function for safe string formatting, which helps to mitigate these risks by enforcing type safety and avoiding the dangers associated with traditional C-style string formatting.

#include <iostream>
#include <format>

int main() {
    int value = 42;
    std::string result = std::format("The answer is: {}", value);
    std::cout << result << std::endl;
    return 0;
}
    

` block with syntax highlighting class `hljs language-php`, which is appropriate if you intend to provide the code in a PHP context (you might want to adjust to `language-cpp` if the focus is purely on C++ code).
