Arrays in C++

1. Definitions

Arrays are useful because they can be used in many ways to store large amounts of data in a structured way.

Arrays are essentially a way to store many values under the same name. You can make an array out of any data-type including structures and classes.

2. Example of array

Here is an example:

#include 

using namespace std;

int main()
{
int x;
int y;
int array[5][5]; // Declares an array 5x5

for ( x = 0; x <= 4 ; x++ ) {
for ( y = 0; y < 5; y++ )
array[x][y] = x + y; // Fill in the array .
}
cout<<"\t\n Array elements :\n"; 

for ( x = 0; x <= 4; x++ ) {
for ( y = 0; y < 5; y++ )
cout<<"["<<x<<"]["<<y<<"]= " << array[x][y] <<" ";
cout<<"\n";
}
cin.get();
}
