C++ :: Program That Compute Final Average Grades Of Class
Jan 28, 2013An instructor needs you to write a program that will compute the final average grades in her class. There are 5 students in the class. Each student must take 2 exams and 4 quizzes as part of their final grade. The weight of each toward the final grade is as follows:
Exam 1 – 30%
Exam 2 – 30% Quiz 1 – 10%
Quiz 2 – 10%
Quiz 3 – 10%
Quiz 4 – 10%
You must use arrays to store each students 3 digit ID number, exam scores and quiz scores. A multi-dimensional array is mandatory. Request from the user the information needed then output all of the information as well as the final average grade for each student.
C++ :: Write Program That Asks User To Enter Student Grades?
Jan 21, 2014Write a program that asks the user to enter a student’s grades on four exams. The program should display the four grades and the average of the four grades,rounded to the nearest tenth. To add the grades, use a variable called total_grade, which you should initialize to zero.As the program prompts for and obtains each grade, add the grade to total_grade using the += operator.

Oct 14, 2014You 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];

C :: Program To Calculate Students Grades From Input File And Write To Output File
Aug 29, 2014One 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, 2014We 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++ :: How To Print Unsigned Char
Apr 23, 2013How do I print an unsigned char in c++? E.g.
unsigned char a[100] = "acdef";
wprintf(L"a is %u
", a);
wcout << "a is " << a << endl;
gives
a is 2880488
a is 002BF3E8
and not
a is acdef
a is acdef
??
what is the difference between unsigned char and char?
C/C++ :: Read And Print A Char Array
Nov 25, 2014In this project I need to develop few functions to work with graphics card. I work in minix and this is pretty rubbish.
I'm having an hard time to read a pixel map, or atleast ro print it on my main function.
I have a read_xpm function, which is given, therefore, working.
char *read_xpm(char *map[], int *wd, int *ht)
then I have a pixmap.h file which gives some examples of pixmap images that I can use as example:
static char *pic1[] = {
"32 13 4",
". 0",
"x 2",
"o 14",
[Code]....
I tried something like read_xpm(xi, yi, *xpm[0]); but I'm guessing I need to index that array and run all those chars in order to show them.

C :: How To Print The Max Number Row In Relation To The Char Arrays Row
Mar 30, 2013I have most of the code working properly, but I'm having trouble with a certain area. Currently I have multiple 2D arrays. One is a char array and the other is an int array. In the int array I have to find the max number in each column, which I've done. The problem is, I need to print the max number's row in relation to the char array's row.
For example,
Code: int array[2][3] = {60 50 30 0 100 1}
The max numbers are 60, 100, 30.
char array[2][length+1] = {nameOne nameTwo}
How it needs to print:
nameOne has max score of 60.
nameTwo has max score of 100.
nameOne has max score of 30.
I just can't understand how to compare the two arrays in the right way, so it'll know that nameOne is associated with the numbers in row 0 and nameTwo in row 1, etc.
C++ :: Print Linked List But As A Vector Of Char

C++ :: Arrays - Determine Grades At The End Of Semester
Jul 18, 2013Write a C++ program that can be used to determine grades at the end of the semester. For each student, who is identified by an integer number between 1 and 60, four examination grades must be kept. Additionally, two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: the first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade a weight of 0.3, an the fourth grade a weight of 0.2; that is computed as:
0.3*grade1 + 0.2*grade2 + 0.2*grade3 + 0.3*grade4
Using this info, you are to construct a 60X7 two dimensional array, in which the first column used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The output of the program should be a display of the data in the completed array.
