Void calculateCostint count, float& subTotal, float& taxCost) ;
Float tax = 0.0,
SubTotal = 0.0;
CalculateCost15, subTotal,tax) ;
Cout << "The cost for 15 items is " << subtotal
<< ", and the tax for " << subTotal << " is " << tax << endl;
//end of fragment
Void calculateCostint count, float& subTotal, float& taxCost)
{
If count < 10)
{
SubTotal = count * 0.50;
}
Else

Methods that call themselves with altered parameters to solve a problem, often used in programming for tasks like sorting and searching.

Infinite Recursion

A coding error where a function repeatedly calls itself without a terminating condition, leading to a stack overflow.

Order of Magnitude

An order of magnitude is a term used to express the scale or size of a quantity, typically in powers of ten, to compare approximate values or changes.

Binary Search Algorithm

An efficient algorithm for finding a target value within a sorted array by repeatedly dividing in half the portion of the list that could contain the target.
