If you need all the elements that are between the delimiters, then Split() is the way to go. If you only need, say, the second element, and you don’t want to allocate memory for the first and third elements, you can use IndexOf to find the delimiters then extract the string using SubString.

If I’m understanding this correctly, what you’re essentially doing is taking the month, adding 1 to it so it is actually the next month. Then you subtract a day from it so it’s the last day of the previous month. It would just be better to give it the actual date instead of doing a … Read more
Remove the = in RemainHP. Right now it is equivalent to Health = Health – Injured; return Health; You want return Health – Injured 2 solved What’s wrong with my C# codes?
Try this: var numbers = textBox1.Text.Split(‘ ‘); List<int> lst = numbers.Select(item => int.Parse(item)).ToList(); It will be even better if you use method group like this: List<int> lst = numbers.Select(int.Parse).ToList(); Then you can get it’s values like this: lst[0] –> 1 lst[1] –> 32 and … 0 solved How to set space between TextBox values into … Read more

var l1 = new List<Class1>(); var l2 = new List<Class2>(); l2.AddRange(l1.Select(i=>new Class2() {locationID = i.locationID, locationName = i.locationName}); 1 solved Copying a C# Collection to another collection [closed]
Anyways I managed to figure out the solution. I executed the query and saved it in a Dataset. Read all the results from dataset and saved the result comma separated in a string. When the user clicks the button the query will be executed and they will be prompted to save the output. String str; … Read more
You should almost always use an algorithm like std::count_if if one is available. The reason is that the compiler vendor can put optimizations in that are not portable if you were to put them in manually in your own loop. For example there are intrinsic functions that could be CPU specific that speed up even … Read more
M is uninitialized! Read M before creating the array a or, make a big enough to contains all possible input sizes and use M to limit the access to a. The latter this is quite common in competitive programming: create a static array big enough and then use only a portion of it based on … Read more
No Html.partial() is not case sensitive. I tested it. For example : Let say Your partial view name is “_HeaDing.cshtml” and its place in the same folder. Then you call the partial view in different cases like below: 1. @Html.Partial(“_heading”)-All characters are in smaller case 2. @Html.Partial(“_HEADING”)- All characters are in Upper case In all … Read more

This should look a bit more like a code intended for humans to read 🙂 #include<iostream> #include<string> using namespace std; int ncr; int me,n=0,u,y,l; char opt1,opt2,opt3,opt4; struct student { string Name; int DoB; int Age; string Address; string Course[5]; char grade[5]; }; void add(); void remove(); void update(); void search(); int main() { int opt; … Read more
A while loop without braces is the same as a while loop with braces surrounding the line immediately below it: int num = 0; while(++num < 6) { Console.WriteLine(++num); } Console.WriteLine(num++); Console.WriteLine(++num); First iteration: while(1 < 6) // num is 1 { Console.WriteLine(2); // num is 2 } Second iteration: while(3 < 6) // num … Read more
You don’t have to downgrade. Visual Studio 2019 and 2017 run side by side. Installing Visual Studio 2019 installs a new application in a different path. It doesn’t upgrade VS 2017, so there’s no reason to downgrade. I’m using VS 2017 and VS 2019 on the same machine for about 6 months now without issues. … Read more
Use #define DEBUG when debugging and use //#define DEBUG when not… Or you can check DEBUG == 1, like #if defined(DEBUG) && (DEBUG == 1) printHex(“Data received\r\n”, recBuff, sizeof(recBuff)); //print out received hex data #endif Hope it helps… 1 solved how to create a #define DEBUG in c
