C++ :: How To Use Bool Function To Get Results For Acceleration
Nov 5, 2013
How to get my data from the file and output, but now I am having trouble with my acceleration function. Right now, I have the acceleration function commented out and the output for acceleration at the bottom because if I try to run the program with them in it the program stops working. working with acceleration calculations and then finally outputting that acceleration.
//Program that reads the time and vertical velocity data and then calculates things from it
#include <iostream>
#include <cstdlib>
#include <vector>
#include <fstream>
#include <iomanip>
using namespace std;
bool calculateAccelerationArray (vector<double> t_array, vector<double> v_array, vector<double>
[Code] ....
The file I'm reading from rocketVelocityData.txt gives me the time and velocity.

I'm having trouble understanding this error I'm getting in my copy constructor and my bool operator in my class methods file.

I'm new to c++ and bought the Jumping in C++ ebook. I read about the bool type but was confused about what it is and when I used it.

Write a function that takes two input arguments and provides two separate results to the caller, one that is the result of multiplying the two arguments, the other the result of adding them.Since you can directly return only one value from a function, you'll need the second value to be returned through a pointer or reference parameter.
Code:
#include "Code.h"
#include <iostream>
#include <string>
double x, y;

Can I do the following? Is it a good practice?
Code:
bool *bAct;
bAct = (bool*) calloc (2, sizeof(bool));
for (i=0;i<2;++i)
{
bAct[i] = true; //initialize
}
I need an array of bools for my application.

Im supose to use <>bool removeTile(char, int, int, char[])<> to do this "function that takes in the choice (D or S) and the two dice numbers and the board as input arguments. When the move is legal and the tile is available for removal, it removes the tile according to the choice by marking the tile as ‘X’. Returns true if the move is successful."

My issue is regardless of which date I input its always defaulting to the values I have set in my constructor in my implementation file in the else statement. So the values always default to 3/15/2006 I think its something to do with the logic in my bool function but I may be incorrect.
header
//date.h header
#include <iostream>
#include <string>
using namespace std;
enum DateFormat {numeric, standard, alternative};
const int MIN_YEAR = 1900;
const int MAX_YEAR = 2015;

Is the bool keyword in C exactly like the boolean keyword in Java? why this code is getting an 'unknown type error' when I initiialze looping.
#include <stdio.h>
#include <stdlib.h>
int main()
[Code].....
If I am completely using the boolean concept wrong in C, should I just use break statements instead?

I am again a bit confused with bool since we have not used them much. I understand it is suppose to return a true or false value that is represented by 0 and 1. so I have these two bool's
bool Triangle::isRight() {
if (pow(largestSide(), 2) == (pow(smallestSide(), 2) + (pow(middleSide(), 2)))) {
return true;
} else {
return false;
[Code] ....
and then I cout to display them
cout << "Is this a right triangle: " << t2.isRight() << endl;
cout << "is this a Triangle: " << t2.isTriangle() << endl;
and i get this
"Is this a right triangle: " 0
"Is this a triangle: " 1
Which i know is correct but I want to replace the 1 and 0 with my own string but the things iv tried tweaking with has not worked.
Also in the file attached has some requirements from my teacher but i was confused at the second last one, --- bool isEqual(Triangle &other) and it says return true if triangles are equal and false if triangles are not.
I dont know if this is just simply if one triangle equals another (however you determine that) or if its for the two bool's, isTriangle() and isRight() or what.

I am designing a database query and need simplification to the algebra:
Code:
((x > u) && (x < y)) || ((z > u) && (z < y)) || ((u > z) && (y < x))
And these are always true:
Code:
z > x
u > y
It's a range overlap algorithm.

How do I do the operation of two integers that gives you the results?
I'm supposed to write a program that:
Asks the user for an integer
Asks the user for one of '+', '-', '*', or '/' (as a character)
Asks the user for another integer
Performs the given operation on the two integers, and prints out the result of
Please enter an integer: 4
Please enter an operation (+, - , *, /): *
Please enter another integer: 5
4 * 5 = 20
Code:
#include <iostream>
using namespace std;
int main() {
int x;
int c;
int d;
char e;

I mean on the executable file. It just displays the results and quickly flashes away, cin.get() has no effect and system("PAUSE") is undeclared.
I never found a single sure way to pause effectively. Is there a method that works all the time? Sometimes cin.get() gets skipped even in the code itself. The IDE I am using is Code Blocks if that matters any.

I have created a game that functions correctly, however, for balancing and future changes, I would like to record results .txt document (its 1v1 btw). I already have code to determine who won and what I am looking for is some way to keep track of different match-ups for the different characters. Im looking for something like this:
loser
Winner char1 char2 char3
char1 3 2 5
char2 2 5 4
char3 8 1 2
the numbers are the amounts of wins a given character has over another character. I'm looking for code to open the .txt file and add 1 to the respective win total so I can do balance changes and such.

I am using Excel 2013, Visual Studio 2015. I began learning about Excel XLL. I wrote simple function which tests whether the argument is missing. Here's code:
#define DllExport __declspec(dllexport)
static LPWSTR rgFuncs[1][7] = { { L"GetSum", L"BU", L"GetSum" } };
DllExport double WINAPI GetSum(LPXLOPER12 arg)
{
if (arg->xltype == xltypeMissing) return -1;
return arg->xltype;
}
This code works as expected: if I miss argument, it gives me -1, and the type otherwise. But when I change code to this:
DllExport double WINAPI GetSum(LPXLOPER12 arg)
{
return (arg->xltype == xltypeMissing) ? -1 : arg->xltype;
}
then, when I miss argument, it gives me 4294967295. Why?

The point of this program is to calculate how many cents the user would have after a certain number of days. The user is given .01 cent on day one, and this amount is doubled with each passing day. I cannot seem to figure out how to add all of the results. Currently, my program simply outputs them to the screen. How do I tell it to add all of the results and store the sum in one variable?
#include <iostream>
#include <cmath>
#include <iomanip>
int main() {
using namespace std;
float totalF = 0;//total amount earned after number of days specified by user have passed

I'm using below code snippet to fetch Youtube video titles, when you enter a query into a listbox, and press the search button:
int resultsn = 0;
void YTReq(string appname)
{
devkey = "my-dev-key-here";
YouTubeRequestSettings settings = new YouTubeRequestSettings(appname, devkey);
request = new YouTubeRequest(settings);
[code].....
But what i get is exactly 500 results, even if i remove the 500 search limit radio-button (i've put that later, after seeing that the search only fetches 500 results). But when i search the same query on YT, i get 1000s of results. What's the wrong with my code?

I am nearing completion of my first real app.. but I noticed a nasty catch in that it consumes 10-20% CPU at idle. I went around commenting features that I suspected may be causing it but it had 0 impact and my CPU usage at idle is still 10-20%.
The program has two threads, one of which is used very little and the second one consume needless CPU.. The only clues a profiler gives me is
MS.Internal.Text.TextInterface.Generics.NativeIUnkownWrapper<MS::Internal::Text::TextInterface::Native::IDWriteFont>...
But the process which takes up all the CPU seems to change every time I start the profiler. Sometimes it is WindowProc or ThreadingProc..
Can how I interpret this and make meaningful changes to how my code runs?
