C/C++ :: GPA Calculator With Text File?

Mar 5, 2015

I'm trying to create a program that will calculate the gpa of several different students, whose data are in a text file. The file looks something like this, with possibly more lines.

Mark 3 4 A 3 D 2 C 1 A
Tom 2 3 A 2 C

The very first number tells us how many credit hour/grades will follow. I have a couple of problems though: From the code I've written I don't seem to get any data other than the first line. Also the gpa that does print out after the file runs is just a 0.00, rather than the actual gpa.

#include<stdio.h>
int main(void)
{

C++ :: Grade Calculator - Output With Comment To A Text File

Feb 24, 2013

I am a math teacher who is taking a programming class. My district wants to incorporate some programming tasks into the high school math curricula. I am working on a project to calculate a final grade and output this along with a comment to a text file. The following data is the input that I created:

3 300 100 100 100 .15
4 400 100 98 94 92 .45
3 300 98 100 92 .40

The final grade output results in gibberish.

#include <iostream>
#include <fstream> // For file I/O
#include <string>
#include <iomanip>
#include <cmath>

using namespace std;

C :: Create File To Write Text And Read Back The File Content

Mar 15, 2013

The Objective Of This Program Is To Create A File To Write Text And Read Back The File Content. To Do That I Have Made Two Function writeFile() To Write And readFile() To Read.The readFile() function works just fine but writeFile() doesn't.

How writeFile() function Works? when writeFile() function Execute It Takes Characters User Type And When Hit Enter(ASC|| 10) It Ask "More?(Y/N)" That Means What User Want? Want To Go Next Line Or End Input?

If "Y" Than Inputs Are Taken From Next Line Else Input Ends.

But The Problem Is When Program Encounters ch==10 It Shows "More?(Y/N)" And Takes Input In cmd variable.If cmd=='Y' I Mean More From Next Line Than It Should Execute Scanf Again To Take ch I Mean User Input.But Its Not!!! Its Always Showing "More?(Y/N)" Again And Again Like A Loop.

Code:
#include <stdio.h>
void writeFile(void);
void readFile(void);
int main(){

C :: Convert List Of Names From One Text File To Email Format In New File

Jan 19, 2014

I have almost a hundred names in a text file that I want to convert to email addresses and save to another file. I seem to have it working, but it doesn't print the full names in the email prefix. The output I'm looking for is Doe_John@livebrandm, but I'm only getting D_J@livebrandm. I'm not sure what I should specifically be reading up on that applies to this directly.

Code:

#include <stdio.h>
#include <stdlib.h>
int main(void)
{
FILE *fpin=fopen("namesIN.txt", "r");
FILE *fpout=fopen("emailOUT.txt", "a");
char first[20],last[20],inbuff[1500];

C :: Writing A Simple File / Text Parser To Read A Config File

Feb 6, 2014

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.

C++ :: Read From A Txt File And Then Write A New Text File With Sorted Line

Jun 11, 2014

I have a .txt file which I want to read from and then write a new text file, this time with sorted lines. It is easy to sort one value, but what about sorting entire lines based on one value?

I want to sort the lines based on the FIRST value.

Example text file contents:

values;data
5.01 100
2.9 342
2.69 43534
10.1 43
6.8 45324

Output: Text file containing

2.69 43534
2.9 342
5.01 100
6.8 45324
10.1 43

It's easy to do this if there was only 1 number on each line, but I do I sort all the lines based on the first number in each line?

C++ :: How To Save File Directory To Text File Using Ofstream

Jul 22, 2013

I'm having a little problem with std:fstream - in my program, the user selects the location of a file which I want to remember. So, I have something like this:

Code: std::string fileLocation;
//Code here creates an 'open file' dialog box which lets the user choose which file to open.
//The string 'fileLocation' now contains the path to the chosen file.
std::ofstream prefs("prefs.txt");
if (prefs.is_open())
{
prefs << fileLocation;
prefs.close();
}

This works fine if the file chosen is in the same directory as the program, however, if they try to choose a directory outside of where the program is kept, it saves the text file into that directory instead of the same one as the program. So, it looks like outputting a directory into an ofstream actually changes the location to which the file is saved.

Is there a way to save the file directory to a text file using ofstream and still have the text file save in the same directory as the program?

C++ :: Convert Text File Containing 0 And 1 To Binary File

Apr 15, 2014

I just wrote a program for Huffman Encoding, where I take a text file, encode it in the form of 0's and 1's, and save that as another text file. However, this does not solve my purpose as it is taking even more space.

So I want to know how do I convert a text file containing these 0'S & 1's to a binary format.

Here is my program:

#include <stdio.h>
#include <string.h>
#include<fstream>
#include<string>
#include<iostream>
using namespace std;
typedef struct node_t {
struct node_t *left, *right;

C++ :: Text File To Binary File

Sep 14, 2013

I want to convert a text file into binary file. I should create the text file by myself. I also use a structure for the components:

struct Data
{
int num;
char name[30];
};

I write information in the text file like this:

Data d;
cin >> d.num >> d.name;
fstream file("Name.txt");
file << d.num << d.name << '
';

If I have entered:
3 Steve
is easy to get this data. I just make another variables and get the data in them:

int num2;
char name2[30];
file >> num2 >> name2;

And everything is done. But what if I have this:

cin >> d.num;
cin.getline(d.name, 100);
file << d.num << d.name;

and the input is:
5 Steve Brown

I can get the number easy like before but how can I get the whole name? If I use:

int num2;
file >> num2;
char a[30];
file >> a;

I get only the first name "Steve". Can I get somehow and the second name in the same variable?

C++ ::  Write Hex In Text File To Other File

Jul 28, 2014

getting hex from a text file and writing it to a different file. I made a program to dump hex from files into a text file and now I need it to save the hex to the original file. Here is my code to save the hex:

int main(int argc, char * argv[]) {
ofstream myFile;
ifstream file(argv[1], ios::in);

It never outputs the correct contents of the file that has been dumped. I've checked with other hex editors and the hex dumper is working correctly.

#include <fstream.h>
#include <string>

C++ :: Write A Calculator Using Two Stacks

Apr 13, 2014

I just started by defining a stack class (stackDouble). I need to write a program that accepts an infix calculator expression, with the following operators (**, exponentiation, /, division, and, -, subtraction. The operator precedence is exponent, division, and subtraction.I need to use a stack of doubles and a stack of strings, of which I can write two classes, or write a single stack template. The user will input the expression just via cin, and there will be a # before every number, a ! before each operator, and a . at the end of the expression. '#', '!', or '.' can be input into a char variable, numbers into a double variable and operators into a string variable.

For example, the following would output 6:

# 3 ! / # 2 ! / # .5 ! ** # 2 .

As stated above, I already made up a stackDouble class. What would I need to do to create the other class (I don't think I want to do it with a template)?

Code:
#include <iostream>
#include <string>
using namespace std;
class stackDouble{
