Let’s try to explain *x = *y; without using the word “dereference”: *x represents the integer object pointed to by x. As it is the left operand of the assignment, it means that this integer object is going to be updated. *y represents the integer object pointed to by y. As it is the right … Read more
In the first code fragment, you are not assigning to d at all. Assignment (=) operator assigns the rvalue (right hand side) to the lvalue (left hand side). This is very standard syntax. solved if-else statement only works in a specific order and I don’t know why [closed]
Here’s a straightforward solution with a simple loop: dict_x = {} for value in list_x: if isinstance(value, str): dict_x[value] = current_list = [] else: current_list.append(value) Basically, if the value is a string then a new empty list is added to the dict, and if it’s a list, it’s appended to the previous list. solved Convert … Read more
I tested it in VS and this works for me: textBox1.Text = textBox1.Text.Replace(“\””, “\”\””); It replaces all ” with “” in my textbox. 2 solved string.replace( char, char) [closed]
It shouldn’t continue, it should throw a NullPointerException that you may intercept in the catch block. When you try if (!spnOptionSelectedTypes.equals(null)) it should throw this exception because spnOptionSelectedTypes is null so it is not a String and does not have any equals() method. Edit: It allows the first if to pass because it has 2 … Read more
No, the “high-end” feature that matters on those ARM CPUs is out-of-order execution, with branch-prediction + speculative execution. In-order CPUs with NEON (like Cortex A-53) aren’t on the list of affected CPUs, because Spectre depends on speculative execution. Spectre primes the branch predictors so an indirect branch in privileged code is mispredicted to go somewhere … Read more
Firstable as I say convWt() is not the same as convWT(). Then, you should never give the same id to each of your input. Try to make this like : var inp = document.getElementById(‘inp’); var convGram = document.getElementById(‘convGram’); var convPound = document.getElementById(‘convPound’); var convMiliGram = document.getElementById(‘convMiliGram’); var convTon = document.getElementById(‘convTon’); var convOunce = document.getElementById(‘convOunce’); function … Read more
You need to specify the newline character when you open the file. On Windows, the default ends up adding an extra ‘\r’. with open(‘quotes.csv’, ‘a’, newline=”\n”) as myFile: writer = csv.DictWriter(myFile, fieldnames=fieldnames) … 1 solved i don’t know why this code is writing empty rows on my csv file when using a PC but not … Read more
If you do new Admin (), you are creating a new instance of Admin and not a spring bean. So you don’t get any advantages which spring provides(for example Dependency Injection) And hence the value is null. Instead you should Autowire it in your class. This way spring will inject the instance of Admin that … Read more

Here is an example with marshal and unmarshal using your object definition package main import ( “encoding/json” “fmt” ) type MyObject struct { ID string `json:”id”` Name string `json:”name”` Planets map[string]int `json:”planets”` } func main() { aa := &MyObject{ ID: “123”, Name: “pepe”, Planets: map[string]int{ “EARTH”: 3, “MARS”: 4, }, } // Marshal out, err … Read more
You wrote about IDs, but in your code is class. <div id=div1>YES</div> <div id=div2></div> <script> var div1 = document.getElementById(‘div1’); var div2 = document.getElementById(‘div2’); if (div1.innerHTML == ‘YES’) { div2.innerHTML = ‘You said YES’; } </script> http://jsfiddle.net/7r9cwf3s/ OR generally, if you want to put into the second one div ‘You said ‘ and content of the … Read more
No. ASCII is a way to encode text in bytes. It is not a programming language. It has no means of expressing logic. Just about every programming language can be expressed in ASCII and can manipulate ASCII encoded data, so you can pick any programming language you like and write your logic in that. 4 … Read more
This is one of the easiest problem ever. This is my solution (since you tagged your post for Python 3): name = input(‘Enter your name: ‘) print(“Welcome”, name) For Python 2, just change input to raw_input, and remove the parenthesis of the print function. 1 solved Ask the user for its name using raw_input [closed]
As others said, you should call sqrt() only with proper values. So better do … #Check discriminant discrim = float((bval**2)-(4*aval*cval)) if float(discrim >= 0): # now it is ok to calculate the roots… root1 = – bval + math.sqrt(discrim) root2 = – bval – math.sqrt(discrim) if float(discrim > 0): print (“Roots at:”, root1, root2) else: … Read more
