Using dynamically-allocated (i.e. [[Heap]]) memory:
<lang cpp> const int n = 10;
try {
int* myArray = new int[n];
myArray[0] = 1;
myArray[1] = 2;
delete[] myArray;
myArray = NULL;
} catch (std::bad_alloc a) {
std::cerr << "allocation failed" << std::endl;
}</lang>
Using fixed (i.e. [[System stack|Stack]]) memory:
<lang cpp> int myArray2[10] = { 1, 2, 0}; /* 3..9 := 0 */</lang>
Using boost::array
<lang cpp> boost::array<int,3> myArray2 = { 1, 2, 0}; </lang>
<nowiki>{{libheader|STL}}</nowiki>
<lang cpp> // STL
std::vector<int> myArray3(10); // make array with 10 elements, initialized with 0
myArray3[0] = 1; // set first element to 1
myArray3[1] = 2; // set second element to 2
myArray3.push_back(11); // append another element with value 11
myArray3.push_back(12); // append another element with value 12
// now myArray has 12 elements: 1, 2, 0, 0, 0, 0, 0, 0, 0, 0, 11, 12
