How to use new operator

[BasicNewbie]

struct student
{
   char name[128];
   int age;
   int gender;
   int courseCode;
};

Sorry for my bad skills , for this code , how I use new operator to create a dynamic array of n student instances? N is an integer that I defined already .

[Moschops]

student* arrayOfStudents = new student[N];

thanks , easy to get what you mean for this code .

by the way , how I want to return the value of the new operator ? in the event the computer cannot allocate the requested memory . Erm , for some example , how should I write the code to check if the new actually succeeded?

sorry .. still in progress of structure since I still having diploma..

If new fails it throws an exception.

try
{
	student* arrayOfStudents = new student[N];
}
catch (std::bad_alloc& e)
{
	std::cout << "The allocation failed!" << std::endl;
}

The first version allocates size bytes of storage space, aligned to represent an array object of that size (or less, if the implementation uses array overhead), and returns a non-null pointer to the first byte of this block. On failure, it throws a bad_alloc exception.

@peter , thanks again . this is the way to check it right?

@moschops , i read the things already , so if I wan to delete the dynamic allocated array that i create in

student* arrayOfStudents = new student[n]

how i delete is

delete[] arrayOfStudents

right?
