Programming Exercise C++ Instructions : 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; a function to output the results. Use appropriate parameters to pass the information in and out of the function. An example of the program output is shown below: Enter the current price of the item: 10 Enter the price of the item one year ago: 8 Enter the price of the item two years ago: 4 Current year inflation: 0.25 Inflation one year ago: 1.00 Inflation is not increasing. Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2. This is what I have so far not sure how to continue. Please Help, Thank you! #include #include #include using namespace std; int main() { double currentPrice; double priceOneYearAgo; double priceTwoyearsAgo; double infCurrentYear; double infOneYearAgo; cout << fixed << showpoint << setprecision(2); getPrices(currentPrice, priceOneYearAgo, priceTwoyearsAgo); calcualteInflation(currentPrice, priceOneYearAgo, priceTwoyearsAgo, infCurrentYear, infOneYearAgo); priceResult(infCurrentYear, infOneYearAgo); return 0; }
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.
Instructions :
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;
- a function to output the results.
Use appropriate parameters to pass the information in and out of the function.
An example of the program output is shown below:
Enter the current price of the item: 10
Enter the price of the item one year ago: 8
Enter the price of the item two years ago: 4
Current year inflation: 0.25
Inflation one year ago: 1.00
Inflation is not increasing.
Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.
