Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :
Doe, John K.
3460 25
Andrews, Susan S.
3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110
Generate the output in the following format :
John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior
The program must be written to use the enum class_level :
enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;
and define two namespace globalTypes (tys and fys) for the function :
class_level deriveClassLevel(int num_of_credits) ;
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy.
and the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits
NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.
For example :
ifstream transferSchoolFile ;
transferSchoolFile.open("student_status.txt", ios::in);
while( !transferSchoolFile.eof()) {
getline(transferSchoolFile,name) ;
transferSchoolFile >> id >> credits;
transferSchoolFile.ignore(); //Used here to ignore the newline character.
….
}
I did this in parts so I got it working with a four year criteria without the user defined name spaces.
include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
[Code] ....
So that worked fine then I tried with name spaces -
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;
[Code] ....

I'm making a Project on a Travel Agency and I need to hide the password entered by the user! I am working on Xcode 5.1.1 -> Command Line Tools -> C++ on my MacBook Pro! Here is what I've tried --
string pass ="";
char ch;
cout << "Enter pass";
ch = getchar();
while(ch != 13){//character 13 is enter
[Code]...
But in the first case the display is -
//Assuming the password is Hello Hello ******
And in the second its giving me 3 errors -
1. Apple Mach-O Linker(Id) Error "_stdscr", referenced from:
2. Apple Mach-O Linker(Id) Error "_wgetch", referenced from:
3. Apple Mach-O Linker(Id) Error clang: error: linker command failed with exit code 1 (use -v to see invocation)
I'm trying to write this c++ programe:
Write a password prompt that gives a user only a certain number of password entry attempts, so that the user cannot easily write a password cracker.
Using FOR Loop. I know this can be easily done using while loop. But I want to know how to do it with for loop aswell.
Here is what I have so far:
Code:
#include <iostream>
#include <string>
using namespace std;
int main ()
[Code] ....
I don't see where the problem is.. The program just executes and does nothing.
What I want is just to make a validation of the users and passwords already set within my array and go to the other form. By the way this form I already made it my start up form on program.cs with the same command I am trying to back to MainForm.
void Button1Click(object sender, EventArgs e) {
string error = "denied";
string[,] usrpass = {{"User1", "pass1"}, {"User2", "pass2"}, {"User3", "pass3"}, {"User4", "pass4"},
{"User5", "pass5"}};

I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?
I have three tables (company,department and employee). Company table has two rows (CompanyID, CompanyName). Department table has four rows (DeptID, DeptName, CompanyID, EmpID). Employee table has three rows (EmpID, EmpName, EmpAddress).
I want to search by Departments For example I want to have one Checkbox named Department if I checked Department it should show me all the available departments in the Company so if i select a particular department it should show me all the employees that they belong to the department that has been selected.

I am doing an assignment that is to calculate the federal tax based on the users input. I am not entirely sure what it is doing, but it is definitely not what I want it to do. I commented out the loops because they seemed to have caused a problem, but there is still problems that are making the program do something else. Here is my code:
#include<iostream>
#include<string>
using namespace std;
double getData();
double taxAmount();
[Code] ....
Functions just seem like they are not my thing. It never gets to the second function to do the calculations and then return to main to display the results.
I tried changing the code to a switch(status) with a default: at the end that looped the "please try again" but for some reason, that was a fail, it created an endless loop.
My assignment is to pixelate an image based on users input. I have a structure that stores the image, and in this structure I'm storing the height and width and a dynamic array of RGBA struct.
This is my function. my main issue (that I've found) is offsetting and figuring out a way to handle the "edge" if the dimensions don't add up to the set pixelation size.
// @------------- Pixelation X
bool filter_pixelation(float percentageX, float percentageY, Picture& pic) {
// URL
/* 50% of 80 = (50/100) * 80 = 40 */
size_t perX = percentageX * (float)pic.width;
size_t perY = percentageY * (float)pic.height;
[Code] ....
Here is the getIndex function:
int getIndex(int x, int y, int width) {
return y * width + x;
}
Okay so I have to draw a square using "c" that draws according to the user input. Also, this has to be a function, and here is the code I have so far:
#include <stdio.h>
void DrawSquare(int length, char symbol);
void DrawSquare(int length, char symbol) {
int row;
int col;
[Code] .....
When I run this program it compiles fine but when the user input is recorded it just draws nothing but makes tons of spaces.

How can i repeat a loop based on the number inputted by the user?
View 4 Replies View Relatedhow to stop outputting data based on a user input. The text file is as follows:
1. a
2. b
3. c
and the code I'm using is as follows:
int main (){
string line;
int search;
cout << "Enter a number from 1-3" << endl;
cin >> search;
search++;
ifstream myfile ("example.txt");
[Code]...
What I want to do is to just output number 1 (the whole line) if the user enters number 1. However, I get an error on the second condition w/c is the "&& line!= search"
I'm trying to create a function where it allows the user to type in multiple amounts of integers, so if the user wanted to have 3 different storages that hold different integers, the input would look something like this:
5
97 12 31 2 1 //let's say this is held in variable "a"
1 3 284 3 8 // "b"
2 3 482 3 4 // "c"
2 3 4 2 3 // "d"
99 0 2 3 42 // "e"
Since we don't know what number the user will input every time, I'm not sure how to create a dynamically allocated array that will create an x amount of arrays every time.. I want to be able to access each index of a, b, c, d, e or however many arrays there are.
So far, this is what I have, but I'm having trouble creating the arrays since it's unpredictable. I'm purposely not using vectors because I don't really get how pointers work so I'm trying to play around with it.
int* x;
int length, numbers;
cin >> length;
x = new int[length]
for (int i=0;i<length;i++)
{
cin >> numbers; //this doesn't work because it only grabs the first line for some reason
x[i] = numbers
}
I am trying to create a program that will calculate pi based on a user input for accuracy. If the user input .3 then when the leibniz infinite sum value at a particular i becomes less then the input of .3 then the loop will exit.
I have looked at a number of examples on the internet but I feel lost. I have put together working code that will infinitely output sums but I need the loop to stop when the sum value is less then the accuracy value.
My question is what is wrong with my while loop, why will it only give me infinite summations? How do I make it so that the loop will exit when my accuracy input is greater then the sum?
int main () {
double accuracy;
cout<<"Give an accurate number." << flush;//looks nice
cin>>accuracy;
int d;//initialize denominator
double pi = 0.0;
while(accuracy < d){
