[ad_1] I will try to explain you how would i go to solve problem. if you road looks like on image, you can use pixel collsion only for part of texture (blue circle) no need to check whole image. And then you check collsions only on edges (protruding parts) of car tiny green circles. other … Read more
[ad_1] You can use Linq only: bool hasAllItems = UserList.All(s => SystemList.Any(mo => mo.Id == s)); 0 [ad_2] solved Check if a list of objects contains another list (only have a property) in C# Linq
[ad_1] Your calculation is alright (not that complicated after all!), I’d just suggest to change your condition statement to reduce a bit your code: double hours, overtimepay, wage; printf(“Enter number of hours: “) scanf(“%f”,&hours); wage=9.73*hours; wage = 9.73 * hours; printf(“Your wage is: %f\n”,wage); if(hours > 40) { overtimepay = (9.73*(hours-40))*1.5; printf(“Your overtime pay is: … Read more

[ad_1] The value have only 2 decimal places is a matter of displaying it, so you just need to print the number of decimal places you are interested in, like float value = 123.123456; printf(“%.2f\n”, value); if you want to dynamicaly specify that number, you can use float value = 123.123456; int decimals = 2; … Read more
[ad_1] A.) vs. B.) B will always copy the first value before checking if the result is 0. A will do the test first, and if the result is 0, it will stop before ever copying the first value. C.) vs. B.) Similar to A, C does the test first, and will never copy a … Read more
[ad_1] Let’s say the domain is as following String domain[] = { a, b, .., z, A, B, .. Z, 0, 1, 2, .. 9 }; Let’s say the password size is 8 ArrayList allCombinations = getAllPossibleStrings2(domain,8); This is going to generate SIZE(domain) * LENGTH number of combinations, which is in this example (26+26+10)^8 = … Read more
[ad_1] There is no need to check the value of d in the while condition if you have the break in each valid case: while (true) { cout << “1.Easy\n”; cout << “2.Medium\n”; cout << “3.Hard\n”; cout << “Choose your difficulty:”; cin >> d; if (d == ‘1’) { a.setdifficulty(“Easy”); break; } else if (d … Read more
[ad_1] Because the type isn’t char. The type is char(*)[640][3] and the declaration would be written as char (*data)[640][3] = new char[480][640][3](); 1 [ad_2] solved Why does this need auto? [closed]
[ad_1] Written as hex, 65280 is 0x0000FF00. So, on common systems with int being 4 bytes, you have set ch[0] to be 0. This is a null terminator, so when you try to print the string, you see an empty string. Note: writing to *p causes undefined behaviour by writing past the end of the … Read more
[ad_1] It means that you’r Send method does not have a return type. Meaning that you don’t return anything in that method. If that method shouldn’t return anything, then just add void as a return type: public void Send(SerialPort serialPort1) { if (serialPort1.IsOpen) { var content = new List<byte>(); content.Add(2); content.AddRange(Encoding.ASCII.GetBytes(CommandText)); content.Add(3); byte[] buffer = … Read more
[ad_1] You can use GroupBy: var voteGroups = Votes.GroupBy(s => s); Now, if you want to know the count of each string use Enumerable.Count: foreach(var voteGroup in voteGroups) Console.WriteLine(“Vote:{0} Count:{1}”, voteGroup.Key, voteGroup.Count()); Another way is using ToLookup: var voteLookup = Votes.ToLookup(s => s); foreach (var voteGroup in voteLookup) Console.WriteLine(“Vote:{0} Count:{1}”, voteGroup.Key, voteGroup.Count()); The lookup has … Read more
[ad_1] Not at all. Java generics are less powerful compared to C++ templates. There is simply no way to express such a template in Java. 15 [ad_2] solved C++ templates to Java Generics [closed]
