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;

Write a program which is used to calculate the GPA based on the grades for different courses input by user. User should be able to use this to enter grades for as many courses as he wants unless he wants to quit. (you may consider using some loop). Once user has completed entering of data, the program should be able to provide a feedback to the user about the GPA. A is equal to 4, B is equal to 3, C is equal to 2, D is equal to 1, rest are 0. Use minimum 5 course to demonstrate working of your code.
Here is an example (User input is in italic and bold):
Would you like to enter grades: Y
Please enter the course name: COSC1301
Please enter your grade: A
Would you like to enter more grades: Y
Please enter the course name:ITSE1301
Please enter your grade: B
Would you like to enter more grades: Y
Please enter the course name:ITSE2409

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)

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 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?

[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
};

how I can make my output only have 2 decimal places because I want it to be a monetary value. In my code I used this:
cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(2);
which worked well at first because on my command prompt screen the numbers had two decimal places and looked liked this:
Premium for Pol1 is $14101.62
Premium for Pol2 is $14221.16
Premium for Pol3 is $582390.50
Premium for Pol4 is $220384.49
However, I also have the program outputting to a textfile called "output.txt" and when I opened this text file the numbers only had one or no decimal places.
Premium for Pol1 is $14101.6
Premium for Pol2 is $14221.2
Premium for Pol3 is $582391
Premium for Pol4 is $220384
How come the code for two decimal places is working for my output to command prompt but not my output to the text file?
Here is my code.
double ratesmn[86] = {
#include "MaleNonSmoker.txt"
- 1
};

I'm supposed to read a text file and display it in the output. I have it down except my formatting. I just cannot get it to just skip one line rather than multiple. I know why though because my char has a max of 11 and if I put a character lets say mango, it is going to fill in the rest with white spaces. It's supposed to display like this:
Mango
Strawberry
Grapes
But instead I get something like this
Mango
Melon
Grapes
I am using isspace but it's not working.

So far I have managed to sort songs by their string length in main. The void function is there because i learned how to create it, but it's not being used because I dont know how to use it.
Expanding on main, how would I go about selecting a random song from the array?

I am building a template for CodeBlocks, which pre-write some includes, the main skull and a header.
This header looks like that :
/**
* @Author Me
* @Description Brief description
* @Date ??
*/
I would like to put the current Date, just after the line @Date, is-it possible ? And if yes, it-is possible to put a field @FileName which copy the filename into the comment ?

I have the following code:
Code:
void Plot(int nx, int ny, double x[350], double y[350], double C_new[350][350], int iplot){
int i, j;
char fname[50];
FILE *fp;
[Code]....
I am then taking the generated file and importing it into a plotting program (Techplot360). It would speed up the importing process if I created a binary file instead of a like above. I know that I need to use fwrite but I am unsure how to handle lines like
Code:
fprintf(fp, "TITLE= ABCDEFG_%d
", iplot); and
Code: fprintf(fp, "%f %f %f
", x[i], y[j], T_new[i][j]);

So I'm trying to output 2 different text files, one has customer names and the other has items they are selling. I gave each customer an ID and each of their items has the same ID. Only problem is when I try to output it, it only outputs the first item with the same ID. I do not want to display the ID number at all, I think getline would show it so I am not using it.
here's my code
ifstream infile, infile2;
string Fname, Lname, email, item, itemPrice;
int id, itemID;
infile.open("Data.txt");
infile2.open("ItemList.txt");
[Code] .....
The first customer shirt item isn't being outputted. Maybe I'm reading the or comparing the info wrong or just not seeing it.
