C :: Pointer To Bool
Oct 21, 2013Can 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.

C++ :: How To Use Bool Remove Tile
Aug 15, 2014Im 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."

C++ :: Bool Logic For Date Validation
Sep 17, 2013My 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.

C++ :: How To Use Bool Function To Get Results For Acceleration
Nov 5, 2013How 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>

The file I'm reading from rocketVelocityData.txt gives me the time and velocity.

C/C++ :: Taking True Bool And Having It Display Statement Instead Of 1 Or 0
Dec 4, 2014I 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.

C++ :: Bool Algebra - Designing Database Query
May 15, 2012I 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.

View 7 Replies View RelatedC++ :: Difference Between Iterator And Pointer
Jan 21, 2013I just figured out that some std functions (for example: copy) need the resource and target objects have iterators to work. Otherwise, the compiler rejects. In case of two arrays, declared as:
double myA[100] = {};
array<double, 100> myB = {};
myA[0] is like a pointer, myB.begin() an iterator, if I do not make any mistake. So, what is exactly the difference between the pointer and the iterator here? They all give the access to elements.
If I need the target of copy to be an array like myA which cannot give an iterator, is there a way to make the command "copy" work for it?
