Conventions used

A block of code is set as follows:
int main() {
Frac f{ 5, 3 };
cout << format("Frac: {}\n", f);
}
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
for(uint64_t i{ 2 }; i < n / 2; ++i) {
if(n % i == 0) return false;
}
Any command-line input or output is written as follows:
$ ./producer-consumer Got 0 from the queue Got 1 from the queue Got 2 from the queue finished!
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
