Does `int` preserve the size?

[short shard]

lets say i have the following

typedef struct STRUCT_FOO {
    int a;
} foo;

void main() {
    long long x = do_something_large();
    foo f = { x };
}

will f.a still work as a long long, or is it now 32 bit?

when creating f, x is narrowed to the size of an int, so the value might not be preserved

it doesn't actually matter whether the int is in a struct or not, you would get the same effect with

long long x = do_something_large();
int f = x;

your compiler can warn you when a narrowing conversion happens, but only when compiling as C++

clang-tidy might catch it otherwise, not sure
