1. Step 1(List down all header file)
#include "stdafx.h"
#include<iostream>
#include<fstream>
#include<iomanip>
#include<string>
#include<cstdlib>
using namespace std;

2. Step 2(Identify all possible
functions)
void viewRecords();//function to view records
void insertRecords();//function to insert
records
void outputline(int, const string, const string); //
prototype of method to output

3. Step 3(Specify your main content)
int main()
{
int ch;
cout<<"File Processing :: Input - Output"<<endl;
cout<<"[1] - View Recordsn";
cout<<"[2] - Insert Records";
givechoice:
cout<<"nchoice: ";
cin>>ch;
switch(ch)
{
case 1: cout<<"nView Recordsn";
viewRecords();
break;
case 2: cout<<"nInsert Recordsn";
insertRecords();
break;
default: cout<<"Invalid"; goto givechoice;
}
}

4. Srep 4 (Outline of the output)
//this will iterate until there's data to read
void outputline(int studentid, const string
name, const string course)
{
cout<<left<<setw(15)<<studentid<<left<<
setw(17)<<name<<left<<setw(10)<<cou
rse<<endl;
}

5. Step 5(Output Process)
/*-------------------insert records------------------------------------*/
void insertRecords()
{
//open the file for input
ofstream outFile;
outFile.open("Student.txt", ios::app);
//check if the file exists
if (!outFile)
{
cerr<< "File could not be opened.";
exit (1);
}
//prompt the user to enter data
cout<<"Enter the 10-digit student number, name and program code."<<endl;
cout<<"Enter end of file to end input."<<endl<<"?";
int studentid;
string name, course;
//user will enter data
while(cin>>studentid>>name>>course)
{
outFile << studentid <<" "<< name <<" "<< course<<endl;
cout<<"?";
}
}

6. Step 6(View Record you input)
//function to view records
void viewRecords()
{
ifstream inFile;
inFile.open("Student.txt"); //open file for output
int studentid;
string name, course;
//print header
cout<<left<<setw(15)<<"Student ID"<<setw(17)<<"Student
Name"<<setw(10)<<"Prog Code"<<endl;
//output the content of the file by calling the function
while(inFile>>studentid>>name>>course)
outputline(studentid, name, course);
}
