For the password validation: Use a do while loop. The condition to terminate would be if the counter reaches three or if the user gets it right. example int counter = 0; boolean passwordCorrect = false; do { Console.Write(“Please enter the password > “); passWord = Console.ReadLine(); //If the password is correct,then it will break … Read more
You have a 2D array. The usual way to traverse it, is be double for loop. The usual order will be this: 1st row – 1st column 1st row – 2nd column .. 1st row – last column 2nd row – 1st column … last row – last column Assume you are using the order … Read more
C# Code for Validation protected void btnSubmitForm_Click(object sender, EventArgs e) { if(txtSome.Text.Length==0) { label.Text = “your message for Required feild!”; } else if(txt2.Text.Length==0) { label.Text = “your message for Required feild!”; } else { //write code here to insert values in database. this block of code will be executed when your all text boxes will … Read more
You probably want this: u64 text[2] ; FILE *input = fopen(“myfile.data”, “r”) ; if (input == NULL) { printf (“Unable to open file\n”) ; return 1 ; } while (!feof(input)) { int charsread ; charsread = fread(text, 16, 1, input) ; // read at most 16 bytes into the text array // process your text … Read more
If you look here: How are arrays passed? Arrays are passed as pointers already, and your implementation of std::swap (which you called “exchange”) is already passing by reference. So that is not an issue in your case. Has your professor complained about your program execution speed? 2 solved How can I make my program faster? … Read more
So, a good first step is to actually write the example data such that it matches the type you’ve requested. Perhaps something like: Mymap[0] = {{{1, 3}, {1, 5}}, 4}; Mymap[1] = {{{2, 3}, {3, 7}, {1, 3}}, 8}; Then, we can pretty easily iterate over this… #include <map> #include <vector> #include <iostream> int main() … Read more
Yes, C++ has implicit casting from bool to int. However, I would suggest you make this a bit more clear that this is your actual intention, so that future readers understand your intent. Explicitly cast it to an int first. int var = 0; for (i = 0; i < 20; i++) { var += … Read more
This looks like a very complex problem for me. Its for sure a optimization problem with many constraints, so i hope you are good at math ;-). I would suggest to have a look at the Simplex Algorithm which will work very well for your problem if you have the mathematical know how to use … Read more
Probably because you’re missing a space to separate the arguments: enable_admin.StartInfo.Arguments = “user ” + “administrator ” + “/active:yes”; ^—- enable_admin.StartInfo.FileName = @”C:\Windows\System32\net”; disable_admin.StartInfo.Arguments = “user ” + “administrator ” + “/active:no”; ^—- disable_admin.StartInfo.FileName = @”C:\Windows\System32\net”; 0 solved How do i use net user inside a C# console program?

Try this int indexModifier = 0; for (int i = 0; i < Math.sqrt(second.Length); ++i) { for (int j = 0; j < Math.sqrt(second.Length); ++j) { second[j + indexModifier, j] = first[i + indexModifier); } ++indexModifier; } 1 solved One Dimensional Array to Multidimensional Array
You can use Listfor this problem. Instead if _lines of type string array use List<KeyValuePair<string,bool>> _lines; And the condition should be if (ScrollLabel._lines[i].Key.Contains(WordsList.words[x]) && !_lines[i].Value) { _lines[i].Value = true; … … } solved How to post new messages in every function call?

for(int i = 0; i < m; i++) { if(i%2 == 0) { for(int j = 0; j < m; j++) printf(“%d “,a[i][j]); } else { for(int j = m-1; j >= 0; j–) printf(“%d “,a[i][j]); } } 0 solved Program to traverse a m*m matrix in inverse s order [closed]
No, that’s not quite correct though it’s close. Think about the properties of all those processes down the left hand side. p0 creates four children, p1 creates three, and so on. Since this is undoubtedly something you’re supposed to nut out yourself, I won’t make it any clearer, that should be more than enough to … Read more
Here is a simple conversion. <?php define(‘LENGTH’, 3); function print_binary($n) { $bit = 1<<LENGTH – 1; while($bit) { echo $n & $bit ? 1 : 0; $bit >>= 1; } echo “\n”; } $n = 1<<LENGTH; for($i = 0; $i < $n; $i++) print_binary($i); ?> 3 solved convert C to PHP [closed]
