As part of a homework problem, I'm trying to declare a new struct within the definition, but my new definition is an array, and I am only to define some of the values. For example:
#define STUDENTS 100
struct Test { int score; int grade;
} score[STUDENTS], ???
but I want to only initialize the first 5. Thanks!

Hi Because it is a homework, I should give you just few hints: 1. Use const types rather than macros: const int STUDENTS = 100; 2. The name of your array and one of its struct members are same: score. use different names. 3. You can intialize the first 5 array elements using array initilizers list almost in the same way as initializing array of integers: int a[100] = { 0, 1, 2, 3, 4 };

I assume your homework is a C++ assignment since you are posting here. Use std::vector<Test> instead of a C-style array, and make Test a class with a constructor.
(And if your teacher is not aware of the standard containers, quit the class and buy a good C++ book instead.)
