Code:
# include <iostream>
# include <fstream>
# include <iomanip>
# include <cstdlib> // needed for exit ()
using namespace std;
int main()
{
ifstream inFile;
ofstream outFile;
inFile.open("registration.txt"); // attempt to open the file for input Student ID first
{
char registration;
if (!inFile.fail()) // if it does not fail, the file exists
cout <<"A file exits by name Registration.txt.\n"
<<" Do you want to continue and overwrite it\n"
<<" with the new information (y or n): ";
cin >> registration;
if (tolower(registration) == 'n')
{
cout << " File cannot be overwritten." << endl;
exit (1); // Terminate program execution
}
}
outFile.open("registration.txt"); // open the file for Writing
if (inFile.fail()) // Successfully Open or Not
{
cout << "\nThe file was not sucessfully opened try again" << endl;
exit (1);
cout << "The file was successfully opened for output." << endl;
return 0;
}
}// I/O file
I need a WHILE loop to read and process all the students
MAKE SURE TO READ STUDENT ID FIRST, THE RANGE OF STUDENT ID IS BETWEEN 1 and 999. The Input file should have up to 12 student's data which I already have in put file.
