Answer:
See Explaination
Explanation:
#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
// namespace std
using namespace std;
// start of the main function
int main() {
// setting precision to 2 decimal point
cout << fixed << setprecision(2) << endl;
// variable declration
int i, count = 0;
int min, max, value, arr[100];
double sum = 0;
double Avg;
// file object creation
ifstream infile;
string file;
// input the file name to read
cout << "Please enter the name of the file to read numbers for Number "
"Analysis program "
<< endl;
getline(cin, file);
infile.open(file.c_str());
// check if file exist or not
// and loop untill you get correct file name
// if you do not want to loop again and again then
// simply return 0; from code
if (infile.fail()) {
cout << "Error opening the file." << endl;
return 0;
// cout << "Please enter the name of the file to read numbers for Number "
// "Analysis program "
// << endl;
// getline(cin, file);
// infile.open(file.c_str());
}
// start reading the data from the file
while (infile >> value) {
arr[count] = value;
count++;
}
// initialize min max to arr[0]
min = max = arr[0];
// find the lowest element
for (i = 0; i < count; i++) {
if (arr[i] < min) {
min = arr[i];
}
}
for (i = 0; i < count; i++) {
// find the highest element
if (arr[i] > max) {
max = arr[i];
}
}
for (i = 0; i < count; i++) {
// calculate sum
sum = sum + arr[i];
}
Avg = sum / count;
// display output
cout << "The highest value is " << max << endl;
cout << "The lowest value is " << min << endl;
cout << "The sum of the numbers is " << sum << endl;
cout << endl;
cout << "The average of the numbers is " << Avg << endl;
return 0;
} // end of the main program
