You want to avoid using \[newline] inside string constants. The c compiler will concatenate string constants for you, so you can format it like this: printf(“Program information\n” “The program reads in the number of judges and the score from each judge.\n” “Then it calculates the average score without regard to the lowest and\n” “highest judge … Read more
You’re on the right track. Just assign a value. int[,] matarix = new int[4, 5]; for (int x = 0; x < 4; x++) { for (int y = 0; y < 5; y++) { matarix[x, y] = VALUE_HERE; } } One recommendation I would make, would be to use Array.GetLength instead of hard coding … Read more
Why do you include so many unneeded header files? These should be sufficient: #include <iostream> #include <string> #include <stdio.h> #include <stdlib.h> #include <time.h> You should avoid using namespace std;. If you don’t want to type std::string every time especially you can use using std::string; using std::string; using std::cout; using std::endl; Now to your function. To … Read more
Here’s one way to accomplish this for all TextBoxes on your Form: public partial class Form1 : Form { public Form1() { InitializeComponent(); } protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { if (this.ActiveControl != null && this.ActiveControl is TextBox) { string replacement = “”; TextBox tb = (TextBox)this.ActiveControl; bool useHTMLCodes = checkBoxUseHTMLCodes.Checked; if … Read more
There are many possible solutions that I can think of. The various solutions are: Reading the input character by character and then upon spaces, creating words out of it. Using a va_list (variable argument list). Continually scanning numbers until the end of line. I am showing you how to implement the first one. The rest … Read more
Change your code into: int main() { int N,count=0,i,j; scanf(“%d”,&N); int A[N]; … 0 solved Find the number of pairs (A[i], A[j]) such that i < j and A[i]**A[j] > A[j]**A[i]
You should try to use valgrind. Valgrind is a debugging tool only requiring for your code to be compiled with the -g flag. It’s the best way to spot segmentation fault over a program, or any memory leak. Think about using valgrind options while debugging (it’s at the bottom of the valgrind report) something like … Read more
Seems like gtk_widget_show() returns void. That’s the void expression you are using in an invalid way. http://library.gnome.org/devel/gtk/2.99/GtkWidget.html solved Error: Invalid use of void expression [closed]
Variable a was not initialized. It has an indeterminate value. 1 solved What are potential issues with the following code? short foo() { short a,b,c; b=10; c = a + b; return c; } [closed]
I do not know what you mean by device (any device located in /dev?), but here is a tutorial on c sockets using write and read: https://vcansimplify.wordpress.com/2013/03/14/c-socket-tutorial-echo-server/ If you would like to gain access to a device in /dev then you just need to open it like a file and also treat it like a … Read more
In my experience even long time programmers doesn’t seem to really grasp linked lists and most try to avoid the afford to get into it since they are part of the standard library and – the fact that some need a full linked list example to understand your question, might reflect that. It took me … Read more
It seems that you have some concept misunderstanding. In every program, there is a memory area called stack where local variables are allocated. In most computer architectures, there is a register called stack pointer (rsp in the x86_64 architecture) which points at the top of the stack (which grows from higher memory addresses to lower … Read more
You can do that easily by passing label as reference ( I’m expecting label to be a double and not a string ) . Here is how void setToValue(double &label , double value ) { label = value; } Note that you don’t need to make the function as type double as it is not … Read more
The many comments (and even answers) focus on the risks in your implementation. Yet the question stands. As directly demonstrated below rectifying the perceived code shortcomings would not change anything significant about the performance. Here is the OP’s code modified to be (A) safe, and (B) supporting the same operations as std::stack, and (C) reserving … Read more
Since you already create (and save) your tasks, the easiest fix would be to await them for each iteration of your while loop: while (run) { action2(); foreach (Task t in continutask) await t; } That way, when all pings completed (successful or not) you start the entire process again – without delay. One more … Read more
