Shorthand if?

Question

C++ / C#

return  a.size() == b.size() ? a < b : a.size() < b.size();

Good day, can you tell me how to write this with the usual *if with else*

Answer 1

This is a ternary operator.
In expanded form it will be like this:

if (a.size() == b.size()) {
    return a < b;
} else {
    return a.size() < b.size();
}
