Question
C++
Write a program that reads the total rainfall for each of 12 months into an array of float from a file named rain.txt. The program should calculate and display the total rainfall for the year, the average monthly rainfall, the highest amount of rainfall, and the lowest amount of rainfall. The file rain.txt contains the rainfall for each month in the year.
Program Requirements:
Implement the following functions in the program:
void readRainfall(float rainFall[])
The function reads the monthly rainfall from the file rain.txt and stores them in the array rainFall
void displayRainfall(float rainFall[], int months);
The months paramter is the number of months in a year. The function displays the output below based on the data in the file rain.txt.
Month Rainfall
1 12.00
2 5.00
3 6.00
4 2.00
5 7.00
6 8.00
7 10.00
8 13.00
9 6.00
10 5.00
11 0.00
12 1.00
float getTotalOfRainfall(float rainFall[], int months);
This function returns the total amount of rainfall. The months paramter is the number of months in a year.
float getAverageOfRainfall(float rainfall[], int months);
This function returns the average amount of rainfall. The months paramter is the number of months in a year.
int getHighestIndexOfRainfall(float rainFall[], int months);
This function returns the index of the array element that has the highest rainfall.
int getLowestIndexOfRainfall(float rainFall[], int months);
This function returns the index of the array element that has the lowest rainfall.
Output
Month Rainfall
1 12.00
2 5.00
3 6.00
4 2.00
5 7.00
6 8.00
7 10.00
8 13.00
9 6.00
10 5.00
11 0.00
12 1.00
The total rainfall is 75.00 inches.
The average amount of rainfall is 6.25 inches.
The largest amount of rainfall is 13.00 inches.
The smallest amount of rainfall is 0.00 inches.
