Thread: printing array

In c++.. you'll know the number of elements in an array because:


1) you will have to initially declare the size of a static array

for example: int array[5]; will have 6 elements.




2) if you are using a dynamic array, you can just keep track of the array size each time you resize the array.

int *array;

int size = 50;

array = new int[size];





3) if you are using a vector, just use the size( ) function.

example: int size = array.size( ); //will return the current size of the array and store into an integer variable named, 'size'
