Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:

The following code is a C++ program that calculates the state and county sales tax for a given amount of purchase. The user is prompted to enter the amount of purchase and the program uses this value to calculate the state sales tax (5%) and the county sales tax (2.5%). The program then calculates the total sales tax (sum of the state and county sales tax) and the total order amount (sum of the amount of purchase and the total sales tax). Finally, the program displays the results including the amount of purchase, state and county sales tax, total sales tax, and total order amount, formatted as currency with two decimal places and a thousands separator. The program uses the cin stream to get the amount of purchase from the user, the cout stream to display the results, and the fixed and setprecision manipulators to format the numbers.
