c++ - This struct is defined, so why does the function think it isn't? -

new c++. making simple struct/array program. why can't pass array of structs intend here?

int numgrads(); int main() { struct pupil { int id; bool isgrad; }; const size_t size = 2; pupil s1, s2; pupil students[size] = { { 123, true }, { 124, false } }; numgrads(students, size); std::cin.get(); homecoming 0; } int numgrads(student stu[], size_t size){ }

i appreciate must passing either reference or value, certainly if i've defined in main(), shouldn't getting error parameter of numgrads?

student defined in main(). define outside of main it's in same scope numgrads:

struct pupil { int id; bool isgrad; }; int main() { ... }

c++ arrays parameters struct undefined
