Question

Write a program that scores the total rainfall for each of 12 months into an array double. A sample array definition is shown below double thisYear[] = {1.6, 2.1, 1.7, 3.5, 2.6, 3.7, 3.9, 2.6, 2.9, 4.3, 2.4, 3.7};

The program should have the four functions to calculate the following 1. The total rainfall for the year 2. The average monthly rainfall 3. The month with most rain 4. The month with least rain
Output:


What to deliver? Your .cpp file including: pseudocode in the beginning of the code, code with other appropriate comments and output at the bottom of your program. Code: 60 points pseudocode: 20 points, Comments: 10 points, output: 10 points


Total Points (100 pts)
The total rainfall for this year is 35 The average rainfall for this year is 2.91667 The month with the highest amount of rain is 10 with 4.3 inches. The month with the lowest amount of rain is 1 with 1.6 inches.

Extra credit: 10 points Instead of initializing the array as above, read the values for the array ‘thisYear[]” from the attached input file rainfall.txt. First read in the values from the array and then do the same as above. Submit that as second problem.

Output: Here’s how the output should look:


1.6 2.1 1.7 3.5 2.6 3.7 3.9 2.6 2.9 4.3 2.4 3.7 The total rainfall for this year is 35 The average rainfall for this year is 2.91667 The month with the highest amount of rain is 10 with 4.3 inches. The month with the lowest amount of rain is 1 with 1.6 inches.

/*
PSEUDOCODE:-

Pseudo code of program

totalRain(){
calculate sum of all values in array
returns the sum
}
  
averageRain(){
calculate average of elements in array
returns the average
}
  
leastRain(){
consider the first number to be minimum
for each of the rest of the number
if it is minimum then the current minimum
assign to minimum
assign index of minimum
returns index of minimum element
}
  
mostRain(){
consider the first number to be maximum
for each of the rest of the number
if it is larger then the current maximum
assign to maximum
assign index of maximum
returns index of maximum
}

{
In the main function

print elementsof array
print"The total rainfall for this year is " and call totalRain()
print"The average rainfall for this year is "and call averageRain()
Call mostRain() and store the value return in indexmost
print"The month with the highest amount of rain is "
and print indexmost and value stored in indexmost
Call leastRain() and store the value return in indexLeast
print"The month with the least amount of rain is "
and print indexLeastand value stored in indexLeast
}

CODE OF THE GIVEN PROGRAM:-

double averageRain(double arr[],int n){

}

//function to calculate least rain
int leastRain(double arr[],int n){
