Write a program that outputs inflation rates for two successive years and whether the

inflation is increasing or decreasing. Ask the user to input the current price of an item and

its price one year and two years ago. To calculate the inflation rate for a year, subtract the

price of the item for that year from the price of the item one year ago and then divide the

result by the price a year ago. Your program must contain at least the following

functions: a function to get the input, a function to calculate the results, and a function to

output the results. Use appropriate parameters to pass the information in and out of the

function. Do not use any global variables. (check for input failure)(C++)

each function has a brief description

Use proper indentation in main function

Use proper indentation in if /switch statements

Use proper indentation in while/do-while/for statements

Use proper indentation for function declarations

Identifiers have meaningful names

Appropriate variable declarations (no global variables)

function for reading the prices

function for calculating the inflation rates

function for displaying message for increasing/decreasing inflation rate

Do not accept a number less than or equal to zero for the prices

proper use of parameters

main function consists of only function calls NOTE: there should be no loops or if statements in the main

Calculations are correct

Program runs without modification

Error message for invalid price

Output message for increasing/decreasing inflation rate
