C++ :: Write A Program To Store Marks Obtained By 50 Students?

Feb 28, 2014

Q.1 Write a program to store marks obtained by 50 students. Initialise the array having passed to a function initilise() having passed the array as parameter. Write another function which should take this array as parameter and return the highest score from the array. you have to write the proper function call, prototype and definition for each function.

And this is the program which i wrote and got errors: -

#include<iostream.h>
#include<conio.h>
#define s 50
void init(int m[s]);
void display(int m[s]);

C :: Enter Test Marks Of Several Students And Calculates Average Marks Of Each Student

Mar 10, 2013

Write a program that a prof can use to enter the test marks of several students and which calculates the average mark of each student. Ask the user how many students he has, then ask him to enter each student's marks. When 999 is entered, calculate the average mark for that student (not counting the 999) and print the average. Then go on to the next students until the marks for all students have been entered, calculated and the average printed.

Code:
#include<stdio.h>
main() {
float student,mark,total=0;
float a,b,c;
int num = 999;

C/C++ :: Program To Store Info About Students And Then Display To Screen

Oct 7, 2014

NOTES AT BOTTOM---EXPLANTION, PROBLEMS ETC. SCROLL DOWN

#include <iostream>
#include <iomanip>
#include <string>

[Code]....

I have to write a program that stores information about students and displays results (Formated). Example-

Inputs ( # of students, First and Last name of student, the gender, age, and hieght. (height inputed as inches and outputed as feet and inches))

Student 2
---------
Jett, Joan Female
100 years old 5' 7"

Ive been falling behind a little due to working late and barely having time for my school work. Coming across several issues, one being an error with GENDER (Error C4700: uninitialized local variable 'gender' used:). As well as how to format the end result, i understand that u have to use #include <iomanip>, but am confused on how to format correctly.

C :: Program To Calculate Students Grades From Input File And Write To Output File

Aug 29, 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 last (2) at 30% each.

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:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

C/C++ :: Program To Compute Students Grades From File And Write Them To File?

Aug 31, 2014

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.

C++ ::  assigning To A Member From Struct Obtained By Overloaded Operator

Jan 27, 2014

I'm trying to assign a value to a member of a struct that I called via an overloaded [] operator. I have the following code for the struct:

typedef struct {
float r, g, b, a;
float operator [](int pos) {
switch (pos) {

[Code] ....

And what I wish to do is

MyStruct a;
a[0] = 0.5;

Is it possible with a struct? How to express this to search engines so I haven't been able to find anything about it. If this is not possible with a struct, is there a way to define something that can do all the following things:

SomeStruct test = {0.5, 0.5, 0.5, 1};
test.g = 1.0;
test[0] = 0.0; // test[0] would be equivalent to calling test.r
float somevalue = test[3]; // test[3] would be equivalent to calling test.a

I hope I've been sufficiently clear.

C/C++ :: Program That Shows All Students Enrolled In Certain Courses

Feb 20, 2014

I'm working on a program that shows all the students enrolled in certain courses.

This is what the correct solution is supposed to output:

enrollmentReport.exe sections0.dat enrollment0.dat

Undergraduate enrollments: 1
Graduate Enrollments: 3

CS 355
23272:Line, S.: 1 students
Squyres, Kristen

CS 571
22000:Caro, Virgil: 2 students
Arnold, Hayley
Aiken, Roberto

22002:Caro, Virgil: 2 students
Belur, Shirley
Aiken, Roberto

This is the output I get:

Undergraduate enrollments: 0
Graduate Enrollments: 0

CS 355
CS 571

I've included all the source code in an attachment. The trick is that I can only modify the section.h and section.cpp

C++ :: How To Store Objects To Program

Nov 14, 2013

I've started programming my little program called vLibrary (program I want to make for the library in my city) and after I m done with console application I will try to implement wxWidgets.My program will be able to add new users to the system, new books and new librarians.

Now, I m confused what data types to use and how to store objects (newly created users, books etc) to my program so later on they can log in the system etc. Logic of the program is completely clear to me but I m not sure how to make array of objects and store them in memory or in a certain file, how to store password and make some kind of encryption etc.which data structure from STL should I use and how.

C/C++ :: Program Which Ask For X Numbers And Store Them In Array

Nov 22, 2014

This is in c. Write a program which asks for X numbers, and stores them in an array.

The program then asks the user to enter a number to look for, and tells the user how many times that number appears in the array of numbers (if any), and the array index which contain the number

Make an array of the indexes where the number was found, and then format your output to match my output.

Sample Run:

How many numbers would you like to enter: 5

Please enter a number:1
Please enter a number:2
Please enter a number:3
Please enter a number:4
Please enter a number:2

The numbers you enter were: 1, 2, 3, 4, 2
Please enter a number to find: 2
The number appears 2 times, at array ellements with indexes 1, 4

Press any key to continue . . .

C++ :: Design ID To Store Vectors For CAD Program?

Mar 3, 2012

Let's say we have entities like lines and circles. And each entity can have a pen attached. And a pen is a color and line width. All entities needs to be manipulated through a operations interface. All entities added to the program needs to be added through using a factory pattern.

So we end up something like (pseudo code)

class Line // for immutable objects {
..
..
} class MutableLine extends Line //for mutable lines {
} MutableLine line=factory->newLine(20,20,50,50); // Create a new line entity

[code]....

So, essentially I want no code to be able to operate directory on entities, unless during creation of the object (color, layer, line width etc...) so I am planning to create Mutable versions of all entities besides the immutable versions.

When requested for selected entities or all entities, I am planning to return a list of immutable objects and in fact I am planning to return a new copy so it's not possible to operate on anything directly.

The reason is that I am planning to create different storage backends swell, so I can operate on entities in a database, or shared memory... stuff like that. At least to hide the internals and provide a stable API.

My questions are:

How can I make sure that people don't do 'tricks' casts for example to a mutable version to change objects directly?

C :: Gradebook Program - How To Store And Access Data

Jun 15, 2013

How I would store all the data. Also how would I access it after I store it. Side Note we are not allowed to use structures or objects.

For the purposes of this gradebook you should first provide a menu with the following options

-Add a new course Add a new student to a course Add grades for a student in a course Print a list of all grades for a student in a course Print a list of all students in a course Compute the average for a student in a course Compute the average for a course Store Gradebook (to a disk file) Load Gradebook (from a disk file)
-Each of these menu items should correspond to a function you will write.
-For the basic program each student will be represented by an ID number And each course by a course number
-Grades will be whole numbers only (no fractional part)

As indicated in the menu you will need to store and load using a disk file so that the data is retained.

Here are so limiting values in defining your data structures: Maximum Number of students (total) 100 Max number of courses 25 Max number of courses per student 4 Max number of grades per student per course 10

C++ :: How To Store Variable In Memory When Program Is Closed

Nov 3, 2013

How do you store a variable in memory so that it isn't changed when the program closes? I don't have any experience with this and am just wondering how it is possible. I am creating a program and want it to store your preferences and scores. In a simple program, everything is just reset and I don't want this for my program. How do I store a variable so that it stays the same, but can be changed even when the program is turned off?

Write a program to store these results in a two-dimensional array, A[4][5], then use a nested for-loop to compute the average of the test results for each experiment and store it in the 5th column of the array. Print the array.

1st experiment results: | 23.2 | 34.8 | 53.7 | 19.5 |
2nd experiment results: | 34.8 | 42.9 | 28.6 | 35.4 |
3rd experiment results: | 24.5 | 29.5 | 32.0 | 19.3 |
4th experiment results: | 36.8 | 31.6 | 43.7 | 29.5 |

6. Using the srand( ) and rand ( ) C++ library functions, fill an array of 1000 numbers with random numbers that have been scaled to the range of 1 to 100 inclusive. Then determine and display the number of random numbers having bvalues between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?

C++ :: Store Related Data Of Program Into External File?

May 14, 2013

How is it possible to store the related data of a program C++ into an external file (like as .txt) and retrieve it?

I want to write c++ program that can contain data members " id and phone"

like as
Code:
class profile {
private: int id,phone;
public:
void retriever() {
cout<<"Enter your ID: ";
cin>>id;
cout<<"Your Phone number is "<< phone;
};
}

avoiding formats in above class, purpose is to store data already in txt file with different id and phone numbers and it is to be retrieved by matching id number to txt file and viewing its related phone number.
