Using the assignment
operator (=) to initialize an array (the
"drudge" method):
|
// this process
could be time consuming (drudgery)
// if a large number of elements are being used
apvector
<double> prices(3);
prices[0] = 19.95;
//filling one element at a time
prices[1] = 29.95;
prices[2] = 42.5;
Note: Unlike Standard C++
arrays, apvector class does NOT let you initialize the elements with a LIST of
different values.

|
Using a for loop and cin
to initialize an array: |
apvector <int>
nums(10);
for(int count = 0; count < 10; count++)
{
cout<<"Please enter a number.....";
cin>>nums[count];
// looping process fills elements
}
|
|
Declare a vector and establish a
"fill" value for all elements: |
// declares apvector
"values" to contain 100 doubles
// and sets all elements equal to 99.9.
apvector <double>
values (100, 99.9);
|
|
Declare an array of strings: |
// be sure all
necessary headers are present
apvector <apstring> names(25);
