Question

C++ need #7 and #8

6. Write code that does the following: Opens an output file with the filename Numbers.txt, uses a loop to write the numbers 1 through 100 to the file, and then closes the file. ofstream outputFile("Numbers.txt"); for(int number = 1; number <= 100; number++) outputFile<< number << endl; outputFile.close();

7. Write code that does the following: Opens the Numbers.txt file that was created by the code you wrote in question 6, reads all of the numbers from the file and displays them, and then closes the file.

8. Modify the code that you wrote in question 7 so it adds all of the numbers read from the file and displays their total.

Answer 1

Answer 7:

#include <iostream>

#include <fstream>

using namespace std;

int main()

{

fstream inputFile;

int num;

//opening the file

inputFile.open("Numbers.txt");

if (inputFile.fail()){

cout << "File open error....";

return 0;

}

//reading the numbers from user and storing in the array

while (!inputFile.eof()){

inputFile >> num;

cout<<num<<" ";

}

return 0;

}

Answer 8:

#include <iostream>

#include <fstream>

using namespace std;

int main()

{

fstream inputFile;

int num,total=0;

//opening the file

inputFile.open("Numbers.txt");

if (inputFile.fail()){

cout << "File open error....";

return 0;

}

//reading the numbers from user and storing in the array

while (!inputFile.eof()){

inputFile >> num;

total+=num;

}

cout<<"Total : "<<total;

return 0;

}
