C :: Computing Grades From Input File And Writing To Output File
Aug 31, 2014
One of my class assignments is to create a program that receive a .txt file containing a students name and their grades as follows: John K. 99, 87, 57, 89, 90, 95 Amanda B. Jones 100, 88, 76, 99, 86, 92 etc.. The number of students is unknown until run time. You have to take those grades and average them weighing the first (4) at 10% a piece and the next (2) at 15% each and the final at 30%. Then return an output file with the students name and their letter grade A,B,C,D,F based on their computed score. In addition, on screen it needs to display the average scores for each Q1, Q2, etc. as well as the minimum and maximum for each test on the screen. I am having a hard time in assigning the scores to a variable so that they can then be computed as an average and then used to determine a letter grade. I have begun to write the code and am a bit stuck..here's what I have so far:
Code:
//
// main.c
// Final Exam
//
[Code].....
The problem I'm having now is how to go about passing the grades to the function computeGrade and then compute the average and return that to the function.

[URL] when I try to write my output to a file. I am building a life insurance premium calculator with c++. What my calculator does is read in a text file called "policies.txt" containing a number of different policies. For example:
Pol1 M N 20 100000 1 .04 99
Pol2 F S 30 100000 1 .05 99
Pol3 M S 72 750000 1 .03 99
Pol4 F N 45 1000000 1 .05 99
And using this, it creates a single premium. Once the calculator calculates the premium of each policy, I want it to write out the premium amount of each policy to a textfile called "output.txt". The problem is that when I check my "output.txt" file, only the premium for the last policy shows up. It only reads:
Premium for Pol4 is 220384
When I want it to read:
Premium for Pol1 is 14101.6
Premium for Pol2 is 14221.2
Premium for Pol3 is 582391
Premium for Pol4 is 220384
How come only the last policy is showing up? and is there any way to make all four policies appear in my output text file? Here is my code:
double ratesmn[86] = {
#include "MaleNonSmoker.txt"
- 1
};

I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line);
outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?

I'm trying to make a program that you input your login info and it writes that info to a text file. Then, later on once I get my problem fixed, the program will read the info to the user. my code is as follows(the input part is a bit lengthy):
// Password Log
#include <iostream.h>
#include <fstream.h>
#include <string>
#include <time.h>
using namespace std;
ofstream login;
[Code] ....
What my problem is when I choose "Input new login info" it automatically inputs I have no clue, and calls next program.

I have a program where I will read in a certain .txt file, such as "financial_data.txt" and I will be doing some sorting with this data.
I want my program to write out the sorted data to an output file and I want the name of the output file to be based off of the input name. For example, since my input file is "financial_data.txt", I want the output file name to be "financial_data_out.txt".
I am having a hard time finding examples online and in my reference manuals...

I have written this code to remove the comments from an input file and then put it into an output file. The program compiles and runs but it removes the whole line of code when it encounters a /* */ type comment. I believe the problem is in the while loop but I just don't know where.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main(void) {
string infile, outfile;
ifstream source;
ofstream target;

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.

So I'm trying to take some information that a user inputs and to then write it into a .txt file. The user would input a student ID followed by 4 quiz grades. I need to use nested loops for the input, a while loop for the outer and a for loop for the inner.
The data in the .txt should would look like:
studentID quiz1 quiz2 quiz3 quiz4
studentID quiz1 quiz2 quiz3 quiz4
etc.
My problem is I'm not sure how to structure the code. I have very few examples I'm working with to understand what I'm working with.

We have to write a program that reads an input file containing data in the form:
Martha J, 80, 90, 90, 100, 89, 99, 85
Anna Smith, 65, 72, 77, 68, 62, 70, 65
Bill Gates, 60, 54, 89, 62, 65, 60, 50
...etc...
and then use that information to determine their letter grade and write that information to a .txt file. I have been able to successfully pass that information to a function to determine their letter grade and have been able to successfully compute their letter grade. However, I can get this information to successfully post within the *computeGrade () function. Yet, I don't know how to pass this information back to the main() on a student by student basis so that I can open a new .txt file and write just their name and letter grade to it.
Another issue I'm having is when it comes to computing the averages of the class. Each score is either a quiz (there are 4), a midterm (there are 2) or a final (there is 1). I'm a little stuck on how to pass say all of the quiz 1 grades as one entity to the function averagesminmax(). Is there a way to compile each of the grades for a specific quiz or midterm as one array and pass that to the function to then do the computation. Also we need the min and max so again from compiling the grades of a particular quiz or exam together as one.
Here's the code that I have so far.
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
const char *computeGrade();
int averagesminmax();
int main() {
char fName[20];
char lName[20];
[code]....
Do I need to re-read the input file and assign them to different variables?
Here's a sample of the output so far:
Enter input .txt file name
Graded
Thui Bhu, 91, A
Ariana B. Smith, 96, A
Emily Gonzales, 83, B
Jennifer L, 89, B
Maria Jones, 67, D
Bill Gates, 55, F
Escobar Morris, 78, C
Anne Latner, 88, B
Program ended with exit code: 0
Also in my output file, the only thing that it prints will be the first name of whatever the last student in the input file list is.

Writing a program to calculate grades... My algorithm is long, so I only posted the part that gives me trouble. When classes== 1,2,4, or 5, the program runs fine. but it terminates when classes == 3.
if (classes==3) {
do {
cout<<"Enter the Letter grade for 1st class. (USE CAPS)"<<endl;
cin>>grade1;

How to structure the input of one .dat file and outputting into another one. I have to loop through a file structured "doe, john, 1500", check for errors and then increase the mp by 50. You also have to do this through using a person class too. I think I need to use a while loop to go to eof and use getline to input correctly, but im not sure how to structure it.
Data file:
Horowitz,Jake,1200.24
Flabitz,Bubba,1712.38
Blackwell,Sharon,1872.93
Molerat,Rufus,501.00

Why my output screen for this program does not want to stay open. It only opens for a split of a second and it's gone. The program is supposed to take numbers from a input file and display and save the manipulation in the output file. Here is the program.

So I am trying to create a program that reads a series of files and creates a graph plotting points from the file. So far my code looks a little something like this -
include <iostream>
include "ccc_x11.h"
include "ccc_shap.h"
include "ccc_win.h"
include <fstream>
using namespace std ;
int ccc_win_main() {
cwin.coord(-10, -10, 10, 10);
[Code] ....
However when I run the program nothing happens. I think it has to do with the way I set up my files, which looks a little something like this-
-9 -9 -9 -9 -9 -9 -7 -7 -6 -6 -5 -5 -4 6 3 1 -1 -3 -6 5 -5 4 -4 2 -2 0
The first thirteen numbers are the x values of the points, and the last thirteen are the y values of the points. Is there any other way to have my program read the file and display the given points?? I would use getline() however that would make my point into a string, and I dont really know how to convert a string to a double before putting the variable into a point.

My code has no errors. I'm just having problems with getting the grades of the file sorted. grades is not a struct, but is a int inside struct School. Below is what I;m having problems with(this is just the code I started working with,I made a few changes but it didn't work,I have no clue)
void selectionSortG() {
Students min;
int key;
for (int i = 0; i < size; i++){
min = student[i];
key = i;
for (int k = i; k < size; k++)

I need to write a program to store a user specified number of grades to a file, with one grade per line. random function to generate grades between a 55 and 100. When you open the file, it should be for writing, and not appending. Again, prompt the user for how many grades to generate, and store them in a file.

I am currently confused on how to get the highest and lowest number from a list of 7 numbers for a File Output. Lets say i have 165 19 654 816 654 987 324. How would i get the 987 for the highest and the 19 as the lowest? Those numbers are not fixed numbers, i need to be able to input any combination of numbers and still be able to get the highest and lowest numbers from the list of 7 numbers.

I have program that is supposed to read in a story from an input file and separate the words and output the lines on which the word occurs. It needs to read in another input file that has a list of words (1 per line) to ignore. i.e. skip them when running through the story. This is what I have so far, I've changed multiple things trying to get it running....
#include<iostream>
#include<fstream>
#include<map>
#include<set>
#include<vector>
#include<string>
#include"split.h"

You are to write a C program that grades a true-false quiz. The quiz data will be available in a text file; here is an example:
Quiz #8 (09/22/14) (corrected version)
TTFTTFTFTF
0080 TTFTTFTFTF
0340 TTFTFFTFTF
The first line in the data file is a comment that you may assume can be up to 80 charac- ters long; it cannot be blank. The second line contains the answer key for the 10-question true-false quiz. The following lines in the data file contain a student's id number in column 1 followed by their answers for the quiz in column 2. A 0 (zero) on a line by itself indicates that there are no more students to process.
Write a program that first reads in (from standard input; more on this in a moment) the comment line and answer key as strings followed by each student's data. Store the student's id numbers in an array. You are to "grade" each student's quiz using the key provided fol- lowed by recording their scores (in a second array) in order to be able to print them out later. You do not need to use an array of strings or characters in your program. Write your program allowing for up to 100 students, and you may assume that at least 1 student will have taken the quiz.
You should create test data text files and provide the data to your program using redirection from the command line (see the sample run below). Your program should output the number of students who took the quiz, the average score, the best score, and a table showing each student's id, score, and grade. The formatting, spacing, and labels in your output should 1 match the sample run below exactly.
Your program should determine each student's grade as follows: if the score is equal to the best score b or b−1, give an A. If it is b−2, award a B. Give C's for any score that is equal to b−3 or b−4, a D for b−5 and an F for all others.
Alright So I'm just stuck at comparing the key answer with student answer here is my code comparing one student's answer with the answer key . is that right ?? One more thing for some reason when i try to print answer[0] the result is nothing why is that
Code:
#include<stdio.h>
int main(void) {
char comment[80];
char answer [10];
char studentans [10];
int n=0,i=0,x=0;
int ID[10];

I am writing a simple file/text parser to read a config file for some code I am working on. It's dead simple and not particularly smart but it should get the job done. The code reads a config file:
Code:
readlength=2500000
start=0
finish=25000000
cutoff=20000
samplingfreq=250000
poles=10
filterpadding=500
}
[code]....
Here is where it gets wierd. You'll notice that there is an unused variable (filepath) in the config struct. This variable is not referenced or used anywhere in the code, ever. Yet if I comment out the declaration of char filepath[1024], the code segfaults partway through the read_config() function.
My best guess is that there is a buffer overflow elsewhere and it just so happens that the memory allocated for filepath happened to be there to catch it up until now, but I can't work out where it might be happening. With the declaration commented out, the read_config() function gets as far as reading the "padding" variable before it crashes. Yet when the declaration is there, then all the variabled are read correctly and everything seems to work.

I know this is how you read from a file. I also want to print my output to the same name of the file plus ".txt". So if my file is called "text" I want to print it to a file called "text.txt".
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
[Code]....
Would it be something like this? Is it better to use "a" or "w" in the fopen? I want to write to it several times.
#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
