C/C++ :: Display Final Results Of Grade Calculation
Sep 14, 2014
I had to write a simple program that prompted the user for various test scores and it would pump out his grade average at the end. I did that with no issue, however, my instructor wants me to add something to the end off the code and I'm not sure how to do that. My code is:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
string tempType;
float SumTest, MaxTest, TestAve,ProgAve,output;
[Code] ....
And this is what I'm supposed to add, the averages are supposed to have numbers from what the user gave.

I'm writing a program to calculate a final grade by adding 4 numbers minus the lowest grade and dividing by 3. My knowledge in c is not extensive I thought that a simple assigment operator would do the job but I'm getting a strange large numbers in the execution.
Code:
#include <stdio.h>
#include <stdlib.h>
main(){
int eg, g1, g2, g3, g4, fg, s1, s2, sg;

I am trying to code a program that takes in user inputted data about percentages and using it to later on calculate a final grade. 4 percents are inputted, for Assignments, Midterm1, Midterm2, and Finals. If the percents dont add up to 1 (i tell the user to enter the decimal value) I set up and if statement to catch it and end the program. Except that if i type in
Assignments = .3
Midterm1 = .3
Midterm2 = .3
Finals = .1
the program doesn't recognize that they add up to 1. Heres the relevant portion of my code [URL] ....
Here's some examples of how it works [URL] ....
And heres what i dont understand [URL] ....
Why is it saying .3 + .3 + .3 + .1 != 1 when .1 + .3 + .3 + .3 == 1?

I need to write a program that will give me multiple calculation results.
#include <iostream>
using namespace std;
int main () {
int x = 8;
int y = 7;
[Code] ....
It only calculates the last two numbers: 1 and 0, so therefor it gives me 1.
But i need to calculate x and y each time they are smaller(incremented) by one digit.
Please note that the int calculation formula needs to stay.

#include <stdio.h>
float total, avg, max, min;
float judge[4];
int index;
int array[4];
int main() {
total = 0.0;
max = array[0];
min = array[0];
[Code] ....
I dont understand how to make the array when it prints out only print out the final average and the final maximum score with the final minimum score but what its doing at the moment is just giving an average for each individual score taken...
Minimum and maximum scores are displaying 0.0
And it displays these things 4 times in a row i just want it to be displayed once.

I have a program that is reading six characters from a text file, swapping every other character(ABCD would read BADC), and then adjusting their value based on a user's adjusted value input. If the adjusted value is 5 then letter A becomes F.
The final output line should print the initial six characters followed by the final six characters after the swap and encrypt adjustment.
I can only manage to print the final characters. Am I far off thinking I need to use pointers to point to the original character values?
One more thing: instructor wants us to complete this project as simply as possible meaning without the use of arrays, loops, switch statements, etc.
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main() {
//declarations
char c1,

I have to accept the numerical grade and determine the letter grade that the user will receive. I have to use a grading table to determine the letter grade based on the numerical grade. The Letter Grade table is
A 90-100
B 80-89
C 70-79
D 60-69
F 59 and below
Here is the code
//preprocessor directives
#include <iostream>
#include <string>
//namespace statement
using namespace std;
//function prototypes
void getData (string& course, string& first, string& last, int& grade);
[Code] ......
As you can see, I am currently stuck on the determineGrade one

I get so close, and then it seems my brain shuts down ... I need to write a program that outputs a histogram of student grades for an assignment. The program should input each student's grade as an integer and store the grade in a vector. Grades should be entered until the user enters -1 for a grade. The program should then scan through the vector and compute the histogram. In computing the histogram, the minimum value for a grade is 0, but your program should determine the maximum value entered by the user. Use a dynamic array to store the histogram. Output the histogram to the console. For example, if the input is:
20
30
4
20
30
30
-1
Then the output should be:
Number of 4’s: 1
Number of 20’s: 2
Number of 30’s: 3
I can't quite get my output to look like that:
/* This program will display the histogram of student grades for an assignment */
#include <iostream>
#include <vector>
#include <stdlib.h>
#include <conio.h>

i'm having trouble with my c programming assignment. i'm trying to convert a number grade to a letter grade. I'm trying to Write a function (called: numToLetter) that takes as input a number from 0 to 100 and returns a character ( a single character ), based on the following: if the number is between 60 and 70 return Dif the number is greater than 90 return Aif the number is between 70 and 80 return Cif the number is between 0 and 60 return Fif the number is between 80 and 90, return B and i need to use the return statements to call the function like for example:
if (a > 90) return ('A');
elseif (a > 80)
return ('B');
elseif (a > 70)
return ('C'); else
return ('F');
how do if write my code with this function?

Just mark the destructor final: [URL] ....
Well, sort of - my question is, since the destructor has to be virtual in order to be marked final (you get an error otherwise), does this cause virtual function overhead anywhere, or add a vtable?

finding the last line of the code? I have a program with two functions that open and display a joke.txt and punchline.txt file. My joke function (which reads the entire file) works fine. The punchline function, however, does not.
void displayPunch(fstream &file)
{
char ch;
string fileLine;
bool isLine = true;
file.seekg(0L, ios::end);
while(isLine)
{
file.seekg(-1L, ios::cur);
[code]....
The file, punchline.txt, has a bunch of garbage strings with one real string at the end. I need extract and display only the final line of that file.

I develop a software using QT 5 open source IDE. Now my question is two-fold:
1. How can I create the final executable file that I can upload for my users? I understand that runtime DLLs shall be required and I have tried Enigma Virtual Box software for bundling runtime files. It does create the file that I can execute from any folder in my PC. However, surprisingly when I transfer that "boxed" file to another PC, it does not run. Both the PCs have Windows 7 installed on them.
2. Secondly, I see possible future issues with Antivirus Softwares. Apparently when I try to run the boxed exe file, it gets rejected by the Antivirus Software on my PC. Is there a way in which I can get my exe file verified/checked/registered by the Antivirus Softwares so that my users don't face any problems in executing the program.
I cannot afford the QT commercial licence, but I am prepared to buy any economical "setup file generating" software (if it exists).

An 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.

Write a C program that calculates the final value of an investment made in a TSX Market Linked GIC.
Specification
The return on this type of GIC (Guaranteed Investment Certificate) is based on the initial investment, the number of years (1, 2 or 3), a minimum return rate, a maximum return rate, a participation rate, the values of the TSX (Toronto Stock Exchange) index at specified intervals during the years, and the type of averaging of these values. The final investment value can only be calculated once all the TSX values are known.
If averaging is not used the TSX rate is determined from the opening and closing values only. If averaging is used the TSX rate is determined by calculating the TSX average at 6 monthly intervals, then is based on this average relative to the opening value. The TSX rate is then multiplied by the participation rate. If this new rate is below the minimum rate, then the minimum rate is used, and if it is above the maximum rate, then the maximum rate is used. Rates are printed to 2 decimal places, and the final investment is rounded down, and formatted using commas.
Only round down for the final investment. If the TSX rate is negative do not print the line for rate adjusted for participation. Assume that the final investment is less than one million dollars. (Hint: if you need to print leading zeros in a number, use the %0m.n format: example - the format specifier %06.2f prints 4.56 as 004.56)
Example 1: See below; averaging is not used, so TSX rate = (107-100)/100 = 7%. After using a participation rate of 80%, get 5.6% (which is between min & max rates).
Example 2: See below; averaging is used over 5 values to get a rate of 68% which equals 54.4% due to participation. This is more than the max rate, so the max rate is used.
The GIC calculator must use the following layout exactly.
+------------------------------------+
| TSX MARKET LINKED GIC CALCULATOR |
+------------------------------------+
Enter initial investment : 1000.00
Enter number of years [1,2,3] : 3
Enter minimum and maximum rates [%] : 1 20
Enter participation rate [%] : 80
Enter if averaging used [1=yes,0=no]: 0
Enter open and close values : 100 107
TSX rate . . . . . . . . . . . . . . 7.00%
Rate adjusted for participation . . 5.60%
Final investment . . . . . . . . . . $ 1,056.00
+------------------------------------+
| TSX MARKET LINKED GIC CALCULATOR |
+------------------------------------+
Enter initial investment : 2000.00
Enter number of years [1,2,3] : 2
Enter minimum and maximum rates [%] : 1 20
Enter participation rate [%] : 80
Enter if averaging used [1=yes,0=no]: 1
Enter 5 TSX values : 200 190 320 430 540
TSX rate . . . . . . . . . . . . . . 68.00%
Rate adjusted for participation . . 54.40%
Maximum rate is applicable . . . . . 20.00%
Final investment . . . . . . . . . . $ 2,040.00 i wrote something like
Code:
#include <stdio.h>
int main (void)
{
int years, minimum, maximum, partrate, x, open, close, tsxvalue;
float investment, tsxrate, y, finalinvestment, maxrate, minrate;
printf("+------------------------------------+

I have to create a program that calculates the final scores per diver, who each get five dives. I have to include the difficulty level when figuring out this score, and I need to drop the highest and lowest scores.
Now, I'm reading from a file where the values are something like:
234 :Diver number
2.3 :Difficulty
2.1 3.2 4.0 2.3 3.8 :Scores
Would I create a parallel array for the difficulty, or include it in a 2D array with the scores. Something like
score[Difficulty][individualScores]; ?
Also, would I include a findMin and findMax in a function that calculates the total, seeing as how the highest and lowest must be dropped to determine the final score?

Write a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: Each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The data in the output file will be nearly the same as the data in the input file except that you will print the names as last_name, first_name and there will be one additional number at the end of each line: the average of the student's ten quiz scores.
The output file must be formatted such that first and last names appear together in a left justified column that is 20 characters wide where the last name comes first, then a comma and a space and then the first name. Use your read string function to read each name separately and then put them together into a larger correctly formatted string before trying to output them. Each quiz score should be listed in a right justified column that is 4 characters wide, and the average should appear in its own right justified column that is 10 characters wide.
Note that if a student has fewer than 10 scores, the average is still the sum of the quiz scores divided by 10; these students are assumed to have missed one or more of the quizzes. The output file should contain a line (or lines) at the beginning of the file providing appropriate column headings.
This is how much I have so far:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
char* read_string(char* buffer, int max_size, FILE* fp);
int main(int argc, char *argv[]) {
FILE *fp_input, *fp_output;
