Written in C++

Declare the following prototypes :

void getPrices(double& current, double& priceOneYAgo, double& priceTwoYAgo);

void calculateInflation(double currentP, double priceOneYAgo, double priceTwoYAgo,

double& infCurrentY, double& infOneYAgo);

void printResult(double infCurrentY, double infOneYAgo);

In the mainline :

Declare variables for inputted values and the outputted values

Set manipulators so the scores are outputted with 2 decimal positions.

Call the getPrices function.

Call the calculateInflation function.

Call the printResult function.

End program.

After the mainline :

Define the functions :

getPrices function

Prompt user for prices and and accept them

calculateInflation function :

Calculate current year inflation rate and place it in a reference parameter

Calculate a year ago inflation rate and place it in a reference parameter

printResult function : Output per the sample executions shown below

Sample Executions :

Sample 1:

Enter the current price of the item: 100

Enter the price of the item one year ago: 80

Enter the price of the item two years ago: 40

Current year inflation: 0.25

Inflation one year ago: 1.00

Inflation is not increasing.

Sample 2:

Enter the current price of the item: 150

Enter the price of the item one year ago: 100

Enter the price of the item two years ago: 80

Current year inflation: 0.50

Inflation one year ago: 0.25

Inflation is increasing.
