Question

C++ Please

Write a program that asks the user for a file name. Assume the file contains a series of
numbers, each written on a separate line. The program should read the contents of the
file into an array and then display the following data:
• The lowest number in the array
• The highest number in the array
• The total of the numbers in the array
• The average of the numbers in the array
If you have downloaded this book’s source code from the companion Web site, you
will find a file named numbers.txt in the Chapter 07 folder. You can use the file to
test the program. (The companion Web site is at www.pearsonhighered.com/gaddis .)

Explanation / Answer

#include<iostream.h>
#include<stdlib.h>
#include<fstream.h>

int main()
{

       int a[100];
       int i=0,j=0, sum=0,av,min,max,odd=0,ev=0;

       ifstream in("numbers.txt");

       while(!in.eof())
       {
           in>>a[i];
           sum=sum+a[i];
           i++;
          
       }

       av=sum/i;

       min=a[0];
       j=0;
       while(j<=i)
       {
           if(a[j]<min)
           min=a[j];
           j++;
       }
       //i=0;
       max=a[0];
       j=0;
       while(j<=i)
       {
           if(a[j]>max)
           max=a[j];
           j++;
       }

       cout<<"Sum is"<<sum<<endl;
       cout<<"Average is"<<av<<endl;
       cout<<"Highest value is"<<max<<endl;
       cout<<"Minimum number"<<min<<endl;
       system("pause");
       return 0;
}
