Is it possible to pass a struct to a function without creating a variable? [duplicate]

Question

In C++ this code is valid

struct foo{
    int x;
};

int bar(foo f);

bar({1});

However I get an error when I try to do something similar in C. Is there way a to pass a struct to a function without actually creating a variable for it?

Answer 1

You need a compound literal for this:

bar((struct foo){1});
