Question

Design a program that lets the user enter the total rainfall for each of 12 months into an array. The program should calculate and display the total rainfall for the year, the average monthly rainfall, and the months with the highest and lowest amount.

PLEASE MODULARIZED THE CODE  

PLEASE USE C PROGRAMMING AND ADD PSEUDOCODE

Answer 1

CODE:

// including stdio library
#include <stdio.h>
float total_rainfall(float a[]);
int get_max(float *a);
int get_min(float *a);
//Main function
int main () {
// declaring array with size 12 to store rainfall values of 12 months
float arr[12],total=0,min,max;
int max_index,min_index;
// loop to input values from user to the array
for (int i = 0; i < 12; i++)
{
printf("Enter Total Rainfall for Month %d : ",i+1);
scanf("%f",&arr[i]);
}
//calling functio to get total rainfall
total = total_rainfall(arr);
// calling function to get maximum rainfall month
max_index = get_max(arr);
max = arr[max_index];
// calling function to get minimum rainfall month
min_index = get_min(arr);
min = arr[min_index];
//print total rainfall
printf("Total Rainfall for the year : %f\n",total);
// printing average monthly rainfall for 12 months
printf("The Average Monthly Rainfall : %f\n",total/12 );
// printing highest rainfall value and the month
printf("Month with Highest Rainfall %f is : Month %d\n",max,max_index+1);
// printing lowest rainfall value and the month
printf("Month with Lowest Rainfall %f is : Month %d\n",min,min_index+1);
}
// function to get total rainfall
float total_rainfall(float *a){
float total=0;
// Loop to calculate total rainfall of the year
for (int i = 0; i < 12; i++)
{
total = total + a[i];
}
return total;
}
// function for getting maximum month index
int get_max(float *a){
//Initially assume maximum value as first element and then check for remaining elements
// whether any element greater than this element or not
int max_month = 0;
// loop calculate maximum rainfall
for (int i = 1; i < 12; i++)
{
// if any element is maximum than current max value..
if(a[i]>a[max_month]){
// store which month have minimum rainfall
max_month = i;
}
}
return max_month;
}
// function for getting minimum month index
int get_min(float *a){
//Initially assume minimum value as first element and then check for remaining elements
// whether any element lesser than this element or not
int min_month = 0;
for (int i = 1; i < 12; i++)
{
// if any element is minimum than current min value..
if(a[i]<a[min_month]){
// store which month have minimum rainfall
min_month = i;
}
}
return min_month;
}

OUTPUT:

PSEUDOCODE:

//This program calculate and display
//the total rainfall for the year,
//the average monthly rainfall,
//and the months with the highest and lowest amount.

take an array of size 12
intially i is 0
for i less than 12{
   prompt "Enter rainfall value for month i"
   }

//Calculate total rainfall

set total to 0;
for every element in array{
   add array element total value
}

//Calculate maximum rainfall month

intitially set max_index to array first element index
for each element in array{
   if element in array greater than max index element
          and store month number as max index element
}

//Calculate minimum rainfall month

intitially set min_index to array first element
for each element in array{
   if element in array lesser than min index element
          and store month number as min element

diplay total rainfall value
display average rainfall by dividing total rainfall with 12
display maximum monthly rainfall month and the month
display minimum monthly rainfall month and the month
