C/C++ :: Calculations From Textfile?
Mar 31, 2014I have a text file that contains values as follows:
2013 05 27 15 52 02.049824 231.401 0.022 49.738
2013 05 27 15 52 02.668822 229.814 0.019 49.738
2013 05 27 15 52 03.283705 228.528 2.599 49.726
2013 05 27 15 52 03.898469 230.140 2.576 49.751
Column1=date, Column2=Month, Column3=Day, Column4=Hour, Column5=Minute, Column6=Seconds, Column7=Voltage(Vrms), Column8=Current(Irms), Column9=Frequency(Hz).
I have to develop a program that will analyse these time-sampled voltage and current measurements over 24 hours and find the total energy used, mean and peak power consumption and Energy used over each hour of the 24 hour period.
How do I go about doing this? I also have to use at least one integration method. The file data contains over 50 thousand lines in the format mentioned above.

C/C++ :: Overtime And Payroll Calculations
Apr 11, 2014When you execute my code you'll notice the regular pay for the first example will calculate to $500 when it is only supposed to calculate to $400. I'm also having a problem adding up the totals of the regular pay and overtime pay to get a total payroll which is displayed in one cout statement. 95% of my code is correct, I'm just having these two issues. To make it more clear hear is my assignment:
The regular working hour for an employee is 40 hours a week. Sometimes employees work over time. When the employee works 40 or less hours, the regular pay is calculated as number of hours worked times the hourly rate. When the employee works over time i.e. beyond 40 hours then the employee's pay has two components a) regular pay (40 hours X hourly rate), and 2) overtime pay (the overtime hours beyond 40 X time and half of the hourly rate).
void compute(incomeInfo *ptrI, int count) {
for (int i = 0; i<count; i++)
if (ptrI->hours <= 40) {
ptrI->regPay = ptrI->hours * ptrI->hRate;
ptrI++;

C++ :: Timer With Non-return Calculations

C/C++ :: Menu Driven Complex Calculations
Mar 18, 2015//complxCalc.cpp//
#include "complx.h"
using namespace std;
ifstream infile ("in.dat");
int main() {
int i = 0;
complx tempComplx;
double d = 4.5;
[Code] ....
//in.dat//
(4,4) (6,7) (2.5, 9.3) (3,8.4) (13, 26.5) (2.2, 3.4)
My plan is to make this a menu driven program, I have already got the program to give the answers but now I want it to give the user choices as well. The first step in this project is to add a menu to the program. The first menu the user sees should ask the user if the program will be taking input from a file or from the user directly via the keyboard. Regardless of option chosen, the user should then be prompted to specify whether a multiplication,subtraction or addition operation should be performed.
If the user originally chose the file input method then the program should proceed to display to the screen the results of those operations on each pair of data elements in the file and terminate. If the user chose to input via the keyboard then the user should be prompted to input the two numbers, perform the operation on those two numbers and display the results to the screen and ask the user which mathematical operation they would like to do next and continue in this manner until the user chooses to exit the program via a menu option. Fortunately the only file that needs to be edited are in.dat and complxcalc.cpp files.
C++ :: Writing Calculations For Unknown Amount Of Students?
Jun 27, 2014I need to create a program that continuously records data until the user enters '0'
The data that I read in is the student's last name, the year of the student (1-4), the major, the gpa, and the advisors name. I then need to print out how many students are in each year (1-4), the number of students each advisor has, the average gpa for each major, and so on. This is what I have, but I am stuck and think that I might be headed the wrong direction because the only thing working is the loop (not my gpa test calc).
//This program displays information pertaining to students
#include <iostream>
#include <string>
using namespace std;
int main () {
int studYear;
double average, studGpa;

C/C++ :: Create Billing System Without Using Pointers - Array Calculations
Feb 17, 2014I am trying to create an billing system "without using pointers". This is my class assignment. In this,
1) User inputs the name
2) The system asks how many items he has purchased
3) Displays a bill number [just a random number]
4) System asks for the item names the user purchased and stores them in an array (of max 10 (ten) inputs (or items))
5) After each item the user inputs, the system asks for the price of the item (stored in an array of numbers)
6) The total bill is calculated, by adding the sum of all prices in the array
I am having terrible difficulties in coding #4 and #5. Somehow, they aren't going well together. Here's what I have:
#include<stdio.h>
#include <stdlib.h>
int main() {
char item[10][10], answer = 'y', name;
int price[10], total_item, total_price = 0, i, j, a, total_bill = 0, max_items = 10, max_char = 10;

C++ :: Output Is Showing Address Instead Of Value
Dec 7, 2013I've run across this issue before, but for the like of me, I can't figure out what keeps causing it. The problem compiles and runs as expected; however in the salaried object (Employee #1 in main.cpp) the console displays the number of vacation days as -858993460 instead of the value entered.
The parent Employee class is abstract with calculatePay() and displayEmployee() being pure virtualls and with a Benefits, Salaried, and Hourly class derived from it.
The Salaried displayEmployee() and the portion of the Main.cpp that contains the salaried object follows. What causing this?
Salaried displayEmployee()
Code:
void Salaried::displayEmployee()
{
cout << endl;
cout << "Employee Information" << endl;
cout << "----------------------------------" << endl;
cout << "Employee Name: " << setw(7) << FirstName << " " << LastName << endl;
