Question

Complete the implementation of the array_stats function. This activity will help you learn how to use counter controlled loops, arrays, global variables, and traversing an array to summarise the contents. This program populates array val with floating point numeric values which are obtained by scanning standard input. At most the first 32 items will be stored in the array, however if fewer than that number are available, then all the available data will be stored. The number of items scanned is saved, and we traverse the array to compute the mean, minimum, and maximum of the items which were read in The general design of your program is as follows: • Global variables: val: an array with capacity to hold 32 values of type double. val_count: an int which is used to remember how many values have been scanned. val_mean: a double precision floating point value which is used to store the mean of the items which have been scanned. val_min: a double precision floating point value which is used to store the minimum of the items which have been scanned. val_max: a double precision floating point value which is used to store the maximum of the items which have been scanned. • Parameters: array_stats expects no arguments. • Returns: array_stats produces no result i.e. the return type is void). • Process: The program should follow the algorithm of introduced in a previous formative exercise to fetch the input data and save it in the array- Where the earlier exercise computed the sum of the input values, this program will be adapted to compute the arithmetic mean of the input values. . In addition to the mean, calculate the minimum and maximum values that appear in the list. The steps required to calculate the maximum value from a list are almost identical to those require to calculate the minimum value. • To calculate the minimum value of a list of items {Xi i=0,..,N-1} = {XⓇ, X1, ..., XN-1}: • Let min • Xa. • For i = 1,..., N-1: if Xi < min then let min - Xi. It is meaningless to compute the mean, minimum, or maximum, of an empty set, so we add the following rule: . If the number of items in the list is 0. then mean = minimum = maximum - 0.

Use the C programming language to complete

#include <stdio.h>
#include <stdlib.h>
#include <float.h>

// Declare Global variables here.

void array_stats() {
// Insert your solution here.
}

#include <stdlib.h>
#include <time.h>

int main() {
// Simulate the test setup process.
srand( time( NULL ) );
for ( int i = 0; i < 32; i++ ) {
val[i] = rand();
}
val_count = rand();
val_mean = rand();
val_min = rand();
val_max = rand();

// Call submitted code.
array_stats();

// Display contents of array val.
for (int i = 0; i < val_count; i++) {
printf("%f ", val[i]);
}

printf("\n");
printf("Item count: %d\n", val_count);
printf("Item mean : %f\n", val_mean);
printf("Item min : %f\n", val_min);
printf("Item max : %f\n", val_max);

return 0;
}

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <float.h>

double val[32];
int val_count=0;
double val_mean=0.000000;
double val_min=0.000000;
double val_max=0.000000;

void array_stats() {
int i;

   val_min=val[0];
for(i=0;i<32;i++)
{   
if(i<32)
{
val_mean=val_mean+val[i];
}
if(val[i]<val_min)
val_min=val[i];
if(val[i]>val_max)
val_max=val[i];

val_count++;
}
  
if(val_count>32)
val_mean=val_mean/32;
else
val_mean=val_mean/val_count;
  
}

#include <stdlib.h>
#include <time.h>

int main() {
  
srand( time( NULL ) );
int i;
for ( i = 0; i <32 ; i++ ) {
val[i] = rand();
}

// Call submitted code.
array_stats();

// Display contents of array val.

for ( i = 0; i < val_count; i++) {
printf("%f ", val[i]);
}
  
printf("\n");
printf("Item count: %d\n", val_count);
printf("Item mean : %f\n", val_mean);
printf("Item min : %f\n", val_min);
printf("Item max : %f\n", val_max);

return 0;
