Question

(1) Prompt the user to enter five numbers, being five people's weights. Store the numbers in an array of doubles. Output the array's numbers on one line, each number followed by one space. (2 pts) Ex: Enter weight 1: 236 Enter weight 2: 89.5 Enter weight 3: 142 Enter weight 4: 166.3 Enter weight 5: 93 You entered 236.000000 89.500000 142.000000 166.300000 93.000000 (2) Also output the total weight, by summing the array's elements. (1 pt) (3) Also output the average of the array's elements. (1 pt) (4) Also output the max array element. (2 pts) Remaining 4 points will consist of: formatting 2pts and comments 2pts Ex: Enter weight 1: 236 Enter weight 2: 89.5 Enter weight 3: 142 Enter weight 4: 166.3 Enter weight 5: 93 You entered: 236.000000 89.500000 142.000000 166.300000 93.000000 Total weight: 726.800000 Average weight: 145.360000 Max weight: 236.000000

Need a basic program in C using the instructions above. Thanks.

Program:

#include <stdio.h>

int main(void) {
   // your code goes here
  
   //create a double array with name weight and size 5
  
   double weight[5];
  
   //create a variable sum that stores the value of the sum of weights
   //initialise it with 0
  
   double sum = 0;
  
   //create a variable to store maximum value of weight
   //initialise it with -1
  
   double max = -1;
  
  
   for(int i=0;i<5;i++){
      
       //taking the input
      
       printf("Enter weight %d: ",i+1);
       scanf("%lf",&weight[i]);
       printf("\n");
      
       //updating the sum variable or adding current weight to previous sum
       sum += weight[i];
      
       //checking if current weight is greater than max
       //if it's greater put value of current weight in max
      
       if( weight[i] > max ){
           max = weight[i];
       }
   }
  
   //printing the weights in single line
  
   printf("\nYou entered: ");
      
   for(int i=0;i<5;i++){
       printf("%lf ",weight[i]);
   }
  
   printf("\n");
  
   //printing the total weight
  
   printf("Total weight: %lf\n",sum);
  
   //average weight = total weight / number of weights
  
   double average_weight = sum / 5 ;
   printf("Average weight: %lf\n",average_weight);
  
   //printing the maximum weight
  
   printf("Max weight: %lf",max);
  
   return 0;
}

Example Output:

Enter weight 1: 236
Enter weight 2: 89.5
Enter weight 3: 142
Enter weight 4: 166.3
Enter weight 5: 93

You entered: 236.000000 89.500000 142.000000 166.300000 93.000000
Total weight: 726.800000
Average weight: 145.360000
Max weight: 236.000000
