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:

Q1) How to use C code to write a C program segment that prompts and accepts the age and number of hours the customer has spent in the “FUNNY Theme Park”. Then, displays the charges based on the rates shown in Figure 2 below : Age Range Rate ( per hour)(RM)0-20 1.0021-50 3.50Above 50 2.00 (Figure 2) In your program, you have to make use of THREE(3) different defined constants for the value of rate per hour and declare the necessary variables.
C++ Programming
b) Wnite a C++ program, which uses a 'switch' statement to respond to different inputs from a user. The user may enter either 1, 2 or 3. If the input is 1, the program asks the user to input two numbers, which correspond to the length and width of a rectangle. The program then calculates the area of the rectangle and outputs the result by displaying the message "This is a rectangle. Its area is: Vvalue. If the input is 2, the program prints out the message "This is a triangle". If the input is 3, the program prints out the message "This is a circle"
