Kirat[ad_1] No, there’s no difference, unless someone’s done something silly to the JavaScript environment. “andrei” is a string primitive, thus typeof “andrei” is “string”. If you do “andrei”.valueOf(), you’re coercing a string primitive into a String object (in theory*) because you’re accessing a property on it (valueOf), and then asking that object for its primitive … Read more
[ad_1] Your constraints are likely not behaving like you expect. My strong suggestion is to use a UIStackView instead, and bind it to the scroll view via constraints, but not your images. let stackView = UIStackView() stackView.axis = .vertical stackView.spacing = 8 // or whatever you want stackView.addArrangedSubview(image1) stackView.addArrangedSubview(image2) scrollView.addSubview(stackView) stackView.translatesAutoresizingMask = false // finish … Read more

[ad_1] You should use if let or guard let. if let name1 = names[“1”] { print(name1) } OR guard let name1 = names[“1”] else { return } print(name1) [ad_2] solved How to get the direct value associated with a key in a dictionary in Swift?
[ad_1] a simple function to do some actions base on input value can be like this : document.getElementById(“myRange”).addEventListener(“change”, function (e) { let value = parseInt(this.value); let resultElm = document.getElementById(“result”); switch (true) { case 0 < value && value <= 20: resultElm.innerHTML = “:|”; break; case 20 < value && value <= 40: resultElm.innerHTML = “:)”; … Read more
[ad_1] You need to tell Visual Studio Code which python interpreter to use. By default, it’s going to use the system python.In your case, it got the Python 3.4.4 version.

[ad_1] This should work: foodArray.filter(obj => filterArray.every(e => !!obj[e.key].find(unit => unit.id === e.id)), ); General idea: check every object in foodArray. Then check if every element from filterArray is found in the array by key. Take a look at:Array.filterArray.everyArray.find [ad_2] solved How can I filter an array of objects by data from another array of … Read more
[ad_1] Your strBlock variable is a local variables within the static initializer block. Its scope is limited to that block, just like any other local variable. If you want to be able to access it in the main method, you’ll need to declare it as a field: static strBlock; // Static field declaration static { … Read more
[ad_1] very probably a reasonable definition of cities (which was much better named City, no reason so have it plural) is typedef struct cities { char name[64]; struct cities * e; struct cities * n; struct cities * s; struct cities * w; } cities; and your problem is to write all the links without … Read more
[ad_1] You missed the trailing “:”: while divisor < n:. There are also various problems with the indentation. This may fix your code: def sum_divisors(n): sum = 0 divisor = 1 while divisor < n: if n % divisor == 0: sum = sum + divisor divisor += 1 # Return the sum of all … Read more
[ad_1] You will want to do the following: char *gg = “hello”; printf( “%c\n”, gg[3] ); This will print the fourth character (zero based array = 0, 1, 2, 3 so 0=’h’, 1=’e’, etc). Change the 3 to which ever character you want, but make sure to not go past the end of the string. … Read more

[ad_1] As Andy Turner said for your first question : clone() is not being used. It just so happens that the variable is called clone, but that has no semantic importance to the code. Concerning the for statement he’s composed of 3 parts ,each separated by one ; , and none of them is obligated … Read more
[ad_1] This is what those functions do exactly: substr() is used to generate a sub-string of specified length from another string. strlen() will return the length of the provided string.
