Answer:
The program in C++ is as follows:
#include <fstream>
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
string filename;
cout<<"Filename: ";
cin>>filename;
ifstream inFile(filename);
if(!inFile) {
cout << endl << "Cannot open file " << filename;
return 1; }
ofstream fout;
ifstream fin;
fin.open("invalid-numbers.txt");
fout.open ("invalid-numbers.txt",ios::app);
double sum = 0; int valid = 0; int invalid = 0;
double num = 0;
while(!inFile.eof()) {
inFile >> num;
if(num >= 0 && num<=110){ sum+=num; valid++; }
else{ invalid++;
if(fin.is_open()){
fout<<fixed<<setprecision(2)<<num<<"\n"; } } }
fin.close();
fout.close();
inFile.close();
cout<<"Total values: "<<valid+invalid<<endl;
cout<<"Invalid values: "<<invalid<<endl;
cout<<"Valid values: "<<valid<<endl;
cout<<"Average of valid values: "<<fixed<<setprecision(2)<<sum/valid<<endl;
double inv;
ifstream inFiles("invalid-numbers.txt");
while(!inFiles.eof()) {
inFiles >> inv;
cout<<inv<<"\n";
}
inFiles.close();
return 0;
}
