Question
This questions was already put individually but I put it together by me someone answer it but in my compiler when I run it the first problem and put the L as it described it goes in an infinite loop of numbers and however the person that did the program it works well. Can someone tell me specificly what to do?On the second problem someone answer it but when I run it it has 58 errors on my dev c++ compiler.
This is the problem I already post, more at the bottom is the answer that someone gave me. I only have a until like 2:00pm or 3:00pm of 5/18/2015 for this and I need to do the Problem analysis and flowcharts.
Write a C++ program, Problem 1. Text Editor using files and strings
In this project, you should write a simple line editor. Keep the entire text on a file, one line in a key Enter. Start the program with entering EDIT file, after which a prompt appears along with the line number. If the letter I is entered with a number n following it, then insert the text to be followed before line n. If I is not followed by a number, then insert the text before the current line. If D is entered with two numbers n and m, one n, or no number following it, then delete lines n through m, line n, or the current line. Do the same with the command L, which stands for listing lines. If A is entered, then append the text to the existing lines. Entry E signifies exit and saving the text in a file. Here is an Example:
EDIT testfile
1>The first line
2>
3> And another line
4>I3
3> The second line
4> One more line
5> L
1>The first line
2>
3> The second line
4> One more line
5> And another line // This is now line 5, not 3;
5> D2 // line 5, since L was issued from line 5;
4> L //line 4, since one line was deleted;
The first line
2> The second line // this and the following lines
3> One more line // now have new numbers
4> And another line
4> E
The answer that someone gave me:
//Program for Text editor using files and strings
#include <iostream> //For io operations
#include <fstream> //for files
#include <string.h> //for string functions
using namespace std;
int readAllFile(char *fname) //read method
{
string line;
int lineno=0;
ifstream file(fname); //Open file for reading
getline(file,line); //reading lne
while(!file.eof()) //if not end of file repeat loop
{
lineno++; //Increment line no
cout<<lineno<<">"<<line<<endl; //Print line
getline(file,line); //read next line
}
file.close(); //Close file
return lineno; //return count of line numbers
}
int appendLine(char *fname, int lineno) //Appending file content
{
char line[50];
fstream file;
file.open(fname,fstream::in | fstream::out | fstream::app); //opened file for appending
cout<<lineno<<">";
cin>>line; //Input line text
file<<line<<endl; //Store to file
file.close(); //Close file
lineno++; //increment line no
return lineno; //Return line no
}
int main(int argc, char *argv[])
{
int lineno=0;
char choice[3]="K"; //For choice input
while(choice[0]!='E') //If E pressed exit loop/program
{
cout<<" ";
lineno++; //Increase line no
cout<<lineno<<">";
cin>>choice; //Input choice L/E/A etc.,
if(strcmp(choice,"L")==0) //If choice is L
lineno=readAllFile(argv[1]); //Call read method
else if(strcmp(choice,"A")==0) //if choice is A
lineno=appendLine(argv[1],lineno); //Call append method
//like this other methods can be implemented and called
}

Problem 2. Movie Database System
Write a C++ program that uses the following structures to store the following data about a Customer:
Name
Address
City, State, and ZIP
Telephone Number
Array of rented movies (Nested Structures)!!!
And the following data about Movie
Title
Year of issue
Duration
The structures should be used to access customer records in a file. The program should have a menu that lets the user perform the following operations:
Create new Customer record
Enter the new record into the file.
Search for a particular customer?s record and display it.
Search for a particular customer?s record and delete it.
Search for a particular customer?s record and change it.
Display the contents of the entire file.
Sort the content of the entire file according to customer name and display it.
Exit
