Question

You are required to write an interactive program that prompts the user for seven (7) real numbers and performs the following tasks:

1. Reads and stores the numbers into one-dimensional array called A.
2. Calculates the sum of the numbers.
3. Find the average of the numbers.
4. Finds the smallest value of the numbers.
5. Prints all the results with proper headings.

Program requirements:

-     The program must contain at least five functions using necessary parameters. These functions should read the data, perform the above tasks, and print the results.

-     The program must be fully documented.

-    You must submit a properly labeled output. .

-     Test your program for different values using real numbers.

Please submit with through comments & spacings/indentations from the source code.

Answer 1

#include <iostream>
using namespace std;
void read_array(float arr[])
{
for(int i=0;i<7;i++)
cin>>arr[i];
}
void print_array(float arr[])
{
for(int i=0;i<7;i++)
cout<<arr[i]<<" ";
}
float compute_sum(float arr[])
{
float sum=0;
for(int i=0;i<7;i++)
sum=sum+arr[i];
return sum;
}
float find_average(float arr[])
{
float sum=0;
for(int i=0;i<7;i++)
sum=sum+arr[i];
return sum/7;
}
float find_min(float arr[])
{
float min;
min=arr[0];
for(int i=1;i<7;i++)
if(arr[i]<min)
min=arr[i];

return min;
}

int main()
{
float arr[7],sum,average,small;
cout<<"Enter seven real numbers : "<<endl;
read_array(arr);
cout<<"THE CONTENTS OF ARRAY:"<<endl;
print_array(arr);

sum=compute_sum(arr);
cout<<"\nSum = "<<sum<<endl;
  
average=find_average(arr);
cout<<"Average = "<<average<<endl;

small=find_min(arr);
cout<<"Smallest = "<<small<<endl;
return 0;
}//end main

input Enter seven real numbers : 4.3 3.5 6.7 8.9 2.1 3.2 6.7 THE CONTENTS OF ARRAY: 4.3 3.5 6.7 8.9 2.1 3.2 6.7 Sum =35.4 Average =5.05714 Smallest = 2.1 . Program finished with exit code 0 Press ENTER to exit console.
