Calculate the Increase or Decrease in The Annual Income Of a Company For Each Year
The program should start by asking the user to enter the company’s annual income for each year starting from year 2000 till 2009. Income must be taken in million. Implementation of following user defined functions are mandatory for this program:
A function
GetAnnualIncome(), which will take and store the income for each year in an input array. The input entered by user should be integer only. The input array should be passed as argument to the function. While taking the input, if annual income entered by the user is a negative value, the program should prompt the user to enter the income again for that year.
A function
CalcIncChange(), which will take two arrays as its arguments. This function will calculate the increase or decrease in the annual income of the company for each year by subtracting the current year income from the income of previous year. For example, to calculate income increase or decrease for year 2001, the following formula can be used:
Income increase or decrease for year 2001 = Income of Year 2001 – Income of Year 2000
Income of year 1999 = 1000 million
The increase or decrease in the income for each year will be stored in another array.
Calculated increase or decrease in the income for each year should also be displayed on the screen. A function CalcChangePercent(), will calculate the percentage of income increase or decrease for each year and then will display this calculated percentage on the screen. The function will take array as its argument and calculates the percentage for each year using the formula given below:
Income increase or decrease in percentage for year 2001 = (Income increase or decrease for year 2001 / Income of Year 2000) * 100
After calculating the percentage for each year, it should be displayed on the screen as well. A function IncDecYears(), will be used to display the years in which the company income increased and years in which company income decreased.
A function MaxIncDecYears(), will take a pointer to an array and by using pointer arithmetic, displays only those two years in which the company faced maximum increase and maximum decrease in its income.
