I told you before, you need to read the documentation and follow the tutorial. This is not the way to set a default value for a model’s field. Please go through the documentation and tutorial at https://docs.djangoproject.com/en/1.5/ If you run into problems during it, come back and ask questions, but if you continue to things … Read more
int() function in Python and Python3 converts a number in given base to decimal. So,in your code: the first line is for asking the user whether how many binary numbers he wants to convert to decimal. Then you are setting the range in for loop. Then you are asking for input with base 2 to … Read more
Try conditionally formatting A2:A12 with the following formula: =IF(ISERROR(SEARCH(“*”&$A2&”*”, $A$1)>0), FALSE, TRUE) (see screenshots below). 1 solved Highlight duplicate values in excel
Please check the below code, what wrong you did are commented in code:- <?php error_reporting(E_ALL); // check all error including warning and notice error too ini_set(‘display_errors’,1); // display errors function add($x,$y) { $result= $x+$y; return $result; } // ; not needed $number1= $_POST[‘n_1’]; $number2= $_POST[‘n_2’]; echo $number1.” + “.$number2.” = “.add($number1,$number2);// using “ is wrong … Read more
This is something I ran into not long ago so trust me on here… Let’s check out this little guy below: if(condition == true) In a way you’re already answering your question, just not comprehending the syntax. (check it out) using System; using System.IO; namespace StackOverflowQA { class Program { static void Main(string[] args) { … Read more
You’re looking for a capture group, which you can then use as a substitution: “-a-“.replace(/-(.)-/g, “<$1>”); // <a> There, the ( and ) define the capture group, the . inside means “any one character here” (adjust as necessary, perhaps .+), and in the replacement string, $1 means “the value of the first capture group.” 5 … Read more
It will be much easier to understand what is happening if you start with what happens closer to the base case of the recursion. Suppose you have fun(0) in your main. inside the body of fun this happens: void fun(int n) { if(n > 0) //this is false, so function does nothing { fun(n-1); printf(“%d … Read more
This is quite basic program called selection sort. The wiki article is: Selection sort. Basically in this program, i is first pointing to the first element in the array. Then, j points to the next element. If, the element j is smaller than element i, they get swapped. After swapping, the inner for loop still … Read more
semilogx will scale the x-axis logarthmically, the same applies for semilogy on the y-axis. The data is exactly the same but sometimes it can be easier to view data where your axes are scaled like this. For example compare the two plots below. x = [0.01 0.1 1 10 100 1e3 10e3]; subplot(121); plot(x, ‘-o’); … Read more
Unfortunately i did not write any query to create the above table causing the error. Assuming that you really meant to say i did not write any query to use the above table; you did implicitly by defining teacher_table table with :- +”FOREIGN KEY(“+courseId+”)”+” REFERENCES “+CourseTable.courseName+”(“+CourseTable.courseID+”)” That is to insert into the teacher_table the value … Read more
You should not attempt to call constructors or destructors explicitly. Assign a new value to the object in the array, like you would with ints or anything else: st[i] = Student(Name_i, id_i); And remove st[i].~Student(); 0 solved How can we assign variable values to a overload constructor separately(not at Initialization) in Cpp?
I did the exact same thing in another part of code and got no error or any problem with it’s way of working but in this part and so it gives me an error. C does not guarantee to diagnose all incorrect code, neither at compile time nor at run time. Nevertheless, you should turn … Read more
You need to attach an event handler to the TextChanged event on TextBox1. This allows you to automatically update the text in TextBox2 when the value of TextBox1 changes. From there the text is split by the space character to break apart the words in the string and we take the first element in the … Read more
As a general disclaimer, you should usually avoid storing CSV data in your tables because it is the epitomy of denormalization. Instead, store each CSV value on a separate row. To add to this problem, SQL Server has no built in function like MySQL’s FIND_IN_SET() which can conveniently search for a string inside a CSV … Read more
