Now that we have Netbeans for C++ properly installed, we start off with a simple example on Array.
An array declaration has the form Name[D] where Name is the name being defined and D is the dimension of the array.
The dimension specifies the number of elements and must be greater than zero. And the dimension must be known at compile time.
#include <cstdlib> #include <iostream> using namespace std; int main(int argc, char** argv) { double height[] = {170, 172, 185}; cout << height[0] << endl; cout << height[2]; return 0; }
In line 8, we are naming the array as height and it’s dimension is 3. The first array value is accessible by height[0] as an array index will always start from 0.
