Let's say I have a product that needs service after 500 hours at 100 RPM. I can dsiplay the remaining hours only as an integer and we only have integer math. Management wants it to display 500 for the first hour, not 499 after the first minute is ticked off. But after a few minutes fullHours will be 499 and partialHours will have some value. I have 3 ways to determine displayHours to suit management and I want to know if the first is ligit.
short fullHours = 500; short partialHours = 0; short displayedHours = 0;
// Method 1 - Is is Kosher to cast a boolean as an int? Is TRUE always a 1 or is that a bad assumption?
i have a Boolean function containing 2D dynamic array, it'll retain either 0 or 1, how can i delete the dynamic array?
bool something (int** a,int b, int c) { int **arr = new int*[b]; for(int i=0;i<b;i++) arr[i]= new int[c]; if (...) return 0; else ... if (...) return 0; }
Now if i were to add true/false values to my arduino string, im not sure to read it. I would like the bool values to enable/disable led jpegs to simulate output status.
rly1_led.enable = newData[15];// if true
Ive tried everything and just cant figure it out. This is my first C# project.
I need writing a macro that would return true/false (1/0) )value. I want to check if a certain element exists in the array. The macro will accept array, its size, and the value to be compared, and must return yes or no. Here is the code that I have written:
Code: #define EXISTS(T, a, n, val) do { char ret=0; T *a_ = (a); size_t n_ = (n); for (; n_ > 0; --n_, ++a_){ ret = (*a_ == val); } } while(0)
My constant vector list is { 'a', 'e', 'i', 'o', 'u', 'y'}. My error comes in on line 20. I am not calling the boolean correctly. If I type in the letter "i". Then the function should output 2 since i is in the 2nd index spot of my vector list. How to fix my error? I am not understanding why my line of code is not working.
So I want to go from having 0 or 1 to having words like false or true. I did it with an if statement earlier today, but I had to get rid of the whole bool thing. I made the variable just a float. But he requires we use bool. Here is my code:
Car y; cout << "Initial value for the Car: " << endl; cout << "Age= " << y.getAge() << " years old. The Price= $" << y.getPrice() << endl; y.setAge(8); y.setPrice(12000); y.setRaceCarStatus(true); cout << "Modified value for the Car: " << endl;
[Code]...
I commented (//) the if statement that I had earlier. If I set RacecarStatus to True, is cout's 1. The starred (*) line right above the comments is the line that I was required to add. I want to cout the actual word true. The one I had this morning won't work anymore.

My problem is that some of my conditions are not being triggered when the price level of a medium or large discount is smaller than the cost of the widget(defined as .40) An example being ,base price, $2 med discount 80%, and large discount 90%. My med discount is,1.6(80%) off of 2, so $.40, which is fine, but 90% off mean 1.8(90%) off of a base of $2, which is $.20 which is too low., and should trigger the 4th if statement, Nick you are discounting large purchases too much!. However when I run this in the program, I am triggering the first if statement.
#include <math.h> #include <stdio.h> #define widget_cost 0.40 int main (){ float sellprice; float discount_med_price;
Why something doesn't work without setting global variables. I want to know how to deliver values for example my boolean value "ende" (means end) from the function in line 99
Code: bool pruefeGewinn() or in line 116 Code: bool spielfeldVoll() to the main function for using it there for Code: } while (ende != true); in line 164.
How to return it correctly?
Here is the Code of the game TicTacToe.
Code: #include <stdio.h> // In- and Output #include <stdlib.h> // Implementation of many functions #include <stdbool.h> // Allows in C99 True and False as Boolean #include <time.h> // Allows using Random by time
I'm trying to test if a character is a vowel. I made a separate function for the test, I'm not really sure how to get my return value to output whenever I call the function from main?
Also, I'm not good with while loops and can't figure out how to get it to continue asking whether or not the user wants to keep entering values.
#include <cstdlib> #include <iostream> using namespace std; bool isVowel(bool); int main(int argc, char *argv[]) { char var1, cont;
I don't know that a Function is the right word for switch/case but it seems like this would exist, is there a way to test multiple booleans using a switch function?
I've just started learning the C language, and I'm stuck on something that is probably quite simple.how to get IF statements working within WHILE loops. My code is below. I am trying to write a program to count the number of words in a sentence, and obviously stop counting after a full stop has been entered. I created a variable called 'spaces' which will increase by one after the user enters a space. However, when the IF statement is in place, the loop never terminates, even if I enter a full stop. When I delete the IF statement, the loop functions correctly.
Code:
#include <stdio.h> int main() { char x; char a; char y; int spaces = 0; }
if (letter3==" "){ letter3==letter; PrintCharacterLineEnd();
This is a code. the string "letter3" contains the string " ". What I want to happen is when, letter3 contains the text " " I want to go to the function PrintCharacterLineEnd.
The problem with this code is that there are no errors showing, but when i compile the program, the if else statements do not carry out as they should do. Both if statements show the same answer, for example the second if statement. If I type Y or N then I get the same thing, 'You will now choose an event'. How do i get rid of this problem? Is char supposed to be used or string?
I have a hit a snag in a number guessing game program. I was given a half-completed program and told to use functions to complete the missing pieces. It looks unwieldy, but this is how it is supposed to be. I have temporarily made the random guess value visible for troubleshooting purposes.
#include <iostream> #include <time.h> #include <stdlib.h> using namespace std; int welcome() { cout << " Welcome to the hi-low game!" << endl;
[code]....
The issue lies within this piece of code:
checkGuess(guess, correct); done = false; //either true or false } while (!done); cout << "Congratulations, you got it!" << endl; return 0; }
I need to manipulate the Boolean variable done so that it registers as false when the user inputs a number higher or lower than the randomly selected value. However, if the user guesses correctly, done will become true and the program will end.
As it stands now, the program will not terminate, and if I set done equal to true like so:
checkGuess(guess, correct); done = true; //either true or false } while (!done); cout << "Congratulations, you got it!" << endl; return 0; }
Every number the user inputs will register as correct instead of the one right guess.
I am working on a small simple program my program fills up a air plane with customers there is 2 levels 1 and 2 and it will put that person in the spot depending on being picked.
So far i made a boolean airplane with 10 spots I can enter 1 person into the airplane with no problem but then after he sits down i get a infinite loop? I assume i maybe have to use the continue statement I feel like there is something simple that im missing i want to add more people. here is what i have
