C++ :: Generate Report Based On Input Received From Text File - User Defined Namespace
Nov 11, 2014
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 :
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>
I know I have some stuff to mess around with but I am currently stuck with two errors, first -
Error1error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartupC:UsersstephenDocumentsVisual Studio 2013ProjectsinputConsoleApplication1MSVCRTD.lib(crtexe.obj)ConsoleApplication1
then -

My main question is did I use the namespaces and enum correctly? And my second question is whats the best way to input the data from the text file? This is really where I get stuck.

So I basically did it in parts and got everything working and then had to make the namespace so I had this:
with this i keep getting an error saying tys::deriveClassLevel: must return a value and tys::fys::deriveClassLevel: must return a value. I have been messing around with this part and struggling I thought I used the namespace to run the if statements with the criteria for the years of school. Basically I have been stuck for awhile and trying to change things around but I cant seem to get it to work.
i want to display all the contents of a file excluding one based on user input say i have 4 records in the file numbered 1 to 4....the user chooses 2 to exclude it outputs records 1,3,4,4 when it should be records 1,3,4 what am i doing wrong here is the code.its basically displaying the last record in the file twice
I'm writing a program that writes to a report in a text file. It uses a struct but with no array. How can I write this so that the report comes out as it should because as of now after i removed the brackets from record which is the variable of the struct my report isn't printing right.
I'm having the upmost hardest time doing this program that basically validates the user's input with a text file. The text file is like so and below that is the work I have so far...
The basic idea of this exercise is to generate words from a user-input, seven-digit number(a phone number). The code runs, but for some reason, I can't get it to print the numbers into the file.
Code: /*Write a program that will generate a word based on a randomly generated, seven-digit number. there should be 2187 possible words. Avoid "phone numbers" that begin with 0 or 1*/
#include<stdio.h> #define PHONE 7 void wordGenerator(int number[]); void wordGenerator(int number[]) { //loop counters for each digit in the number
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.
how 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){
I am studying about recursion by myself and i want to make a recursive function that prompts the user to input the base and exponent and generate the final answer .
#include<iostream> using namespace std; int recursive(int x, int y); int main() { /*int total=1; int y, x;
I need to create a program that prints a certain number of asterisks based on user input. The user inputs 5 and I want my program to output "*****". How would I do this in C? I've tried printf("%#**", myvariable) but this does not work it only prints "*".
I am a beginner with C++, taking a class right now. The lab this week is to create a user defined class and have it accesses in a separate .h header file from the main.
I think I'm finding my way through it, but I'm getting a complie error that makes no sense to me:
I have code that reads an input file and generates an output file .For reading the input file we have a xml file.If there is an error while reading or writing the output file the an errored file is generated. But in the errrored file the fields are not coming as in accordance with the reader xml . They are coming randomly . In the module for reading and writing the errored file list is being used . What should be done to write in the errored file as the reader xml fields.

I need to create a list of all members of a struct using the sturct definition as input. The struct is NOT part of the program, but is the input to the program.
The struct that I am using changes over time as features are added. I need the complete, fully qualified field names to then generate a table with all names with their offsets, type and length.
This information then allows me to create readers of the data that will run on different architectures, compilers and operating systems.
The struct currently has 800+ lines and uses typedef and embedded structs.
Perhaps this could be done creating LEX, YACC, Perl, SED, AWK or other language system.
