Question

Greetings everyone, i have this assignment in "C" LANGUAGE and im trying to use three loops in a array but im missing one loop. here are the instructions.

Write a small program that:

fills an array of doubles with user input,

prints the doubles on the screen in a column,

adds up all the doubles in the array

prints the sum onto the screen.

- You must use at least 3 functions
- Declare an array of doubles of size 12.
- Prompt the user for how many doubles they want to enter <= 12.
- Use a loop to read the doubles into the array from the keyboard.
- Use a loop to print the array onto the screen in a column.
- Use a loop to add up all the items in the array and store the sum
- print the sum onto the screen

Please help me and it is in program C not C++.

Thank you

Explanation / Answer

// C code
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>

double calculateSum(double doubleArray[],int n)
{
   int i;
   double sum=0;
   // Use a loop to add up all the items in the array and store the sum
   for(i=0;i<n;i++)
   {
   sum=sum+doubleArray[i];
   }
   return sum;
}

// Use a loop to print the array onto the screen in a column.
void displayArray(double doubleArray[],int n)
{
   int i;
   printf(" Double Array: ");
   // Use a loop to print the array onto the screen in a column.
   for(i=0;i<n;i++)
   {
   printf("%lf ",doubleArray[i]);
   }
}

int checkSize(int n)
{
   if(n >= 1 && n <= 12)
       return 1;
   else
       return 0;
}

int main()
{
   // Declare an array of doubles of size 12.
   double doubleArray[12];

   // Prompt the user for how many doubles they want to enter <= 12.
   int n,i;

   while(1)
   {
       printf("How many doubles you want to enter.(less than equal to 12): ");
       scanf("%d",&n);

       if(checkSize(n) == 1)
           break;
       else
           printf("Invalid Input ");
   }

   // Use a loop to read the doubles into the array from the keyboard.
   printf("Enter the doubles ");
   for(i=0;i<n;i++)
   {
   scanf("%lf",&doubleArray[i]);
   }

   displayArray(doubleArray,n);

   double sum=calculateSum(doubleArray,n);
  
   printf(" Array sum:%lf ",sum);

   return 0;
}

/*
output:

How many doubles you want to enter.(less than equal to 12): 20
Invalid Input
How many doubles you want to enter.(less than equal to 12): 5
Enter the doubles
1
2
3
4
2

Double Array:
1.000000
2.000000
3.000000
4.000000
2.000000

Array sum:12.000000
