This program is basically working. I'm very knew to C++, so basically I need instructions as if you were explaining this to your grandma. I need this to loop but how to incorporate one. Basic code (while loops). Here is what I've done so far.
#include <iostream> using namespace std; int main () { int i, c, k; cout << "Please enter a number to convert: "; cin >> i;
I am trying to convert uint32_t or unit16_t to chars in little endian. When I was reading the char s from binary file I used memcpy so I did not need to convert them, but now I try this:
In the last function I try either to cast to uint_32_t or unsigned char but in both case I got wrong values. The original binary string read from left: 0x36000003 (it is number corresponding to 48Mbytes).
And the result when casting to unsigned char is T000000 and T(>00 for uint_32. So what's wrong? I need to get some string with will be corresponding to 0x36000003. does this kind of convertion take a lot of compute performance when I one would use it offten (like when one would do convesions for bitmaps).
I'm expected to write a c program for this question :
Using these header files #include <stdio.h> #include <conio.h>
Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.
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.
Requirement: the AddRegistration method in the RegistrationDB class should accept a Registration object and return a Boolean value that indicates if the operation was successful
a brief overview. Form with two combo boxes and a button, when you click the button the data from the combo boxes is entered into a table in the connected database...
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;
