[ad_1] Dictionarys are mappings from a key to a value. ContainsKey() checks if your dictionary contains a certain key, it is very fast – looking up keys (and finding the data associated with that key) is the main strength of dictionaries. You might need this, to avoid accessing a non-existent Key – read about TryGetValue() … Read more
[ad_1] Well , you can create a new array to put the numbers shifted so you dont get confused with the temps and simplify your code: int new_array[n]; for(int i=0;i<n;i++){ new_array[(i+m)%n]=array[i]; } [ad_2] solved Program to shift elements in an array (Not getting correct output) [closed]
[ad_1] You should probably look at message queues (the Microsoft version is called MSMQ and is built into Windows. Other message queues are available). They are designed for exactly this sort of scenario. Essentially, your application write an event to it’s local message queue. This will attempt to send it to the remote queue (on … Read more
[ad_1] You Could Well Do This First Make a char array , Containing Number Of Maximum Stars that will be asked to print. char stars[] = “***************************************”; Then Ask User Input for number of stars they want to print. int a; printf(“Enter Number of Stars You Want To Print : “); scanf(“%d” , &a); Then … Read more
[ad_1] To keep it simple, in case A, your program has to initialize i only once. Assign values to i only array.Length times. Increase i values only array.Length times. do the line execution and comparison 2*array.Length times. In case B, initialize i twice. Assign values to i 2*array.Length times. Increase i values 2*array.Length times. do … Read more
[ad_1] Why do I have to skip the month of february in the for loop and use mes->fevereiro[j] instead of mes->meses[1][j]? [closed] [ad_2] solved Why do I have to skip the month of february in the for loop and use mes->fevereiro[j] instead of mes->meses[1][j]? [closed]
[ad_1] As for loading the functions, take a look at this page. And also, don’t forget about context creation. As for setting it up in Visual Studio, you would probably just need to link OpenGL lib files (opengl32.dll for windows, .so for linux, etc..) This snippet might be useful (taken from the first link): void … Read more
[ad_1] I think the line if (op = ‘y’) { is the culprit. It should be a double equals if (op == ‘y’) { 4 [ad_2] solved Why does nested if statement is not working? [closed]
[ad_1] I’d advise against using == to test string equality. Use String.Equals() instead. You can also do this in one statement using Linq: if ((new [] {string1, string2, …}).Any(s=>string.equals(s,”No”,StringComparison.CurrentCultureIgnoreCase))) { DoStuff(); } This will DoStuff() if any of your strings are equal to “no” ignoring the case. See String.Equals() and Enumerable.Any() for further reading. It … Read more
[ad_1] The code to set the value is actually executed in Form1‘s context only. Since you made it a static field without understanding what you are doing that initialization code does not get a chance to execute and code in Form2 happily sees the null value. So says my psychic debugging about this ill-defined problem … Read more
[ad_1] Very briefly: ((u8_t *)addr)[0] First octet of addr. %02x This is a format string for the printf family of functions. It will print a hexadecimal number padded to 2 digits (e.g. 5c). ((struct uip_udpip_hdr *)&uip_buf[UIP_LLH_LEN]) A struct uip_udpip_hdr at the offset UIP_LLH_LEN from uip_buf in memory. static struct uip_udp_conn *server_conn A static pointer to … Read more
[ad_1] There’s no separate notion of struct in C++. struct is a keyword. Entities introduced by this keyword, and also by class and union keywords, are called classes. The standard uses the term “non-union class” to distinguish classes that are not unions. [ad_2] solved Hypernym for class an struct in C++
[ad_1] it’s ok now for (int i = 4; i > 0; i–) { for (int j = 1; j <= i; j++) Console.Write(“*”); Console.WriteLine(); } [ad_2] solved How to reverse for loop in c# for string type ? i need to remove one character each iteration
[ad_1] Not sure if this is the best way, performance wise, but it is the most logical way to me. copy_if seem to not exist. But looking at ASCII table www.asciitable.com I loop through the character array and only copy the alphabetic numeric character to my string object, and until I find a space or … Read more
[ad_1] You cannot have any strictly ANSI compatible event loop on Linux, because the purpose of an event loop is to multiplex cleverly several inputs; on Linux to do that multiplexing, you have to call some syscalls like poll(2), pselect(2) or friends, and all these syscalls are not standardized in ANSI C (or ISO C99, … Read more
