From C++1z/17, you can use structured bindings: #include <iostream> #include <map> #include <string> int main() { std::map<int, std::string> m; m[1] = “first”; m[2] = “second”; m[3] = “third”; for (const auto & [key, value] : m) std::cout << value << std::endl; }
Right click on the folder you want to add it to and choose “New file…” From the Dialog – create a new Resource file of type Property List: Give it whatever name you want, the plist extension will be added for you. In this case I’ve created Root.plist This will bring up a blank file … Read more
You can escape every thing in properties file with Java Unicode: \u003d for = \u0020 for whitespace For example: foo bar = barefoot must be: foo\u0020bar\u0020=\u0020barefoot So will be: key: “foo bar ” value: ” barefoot”
You can use the IDictionary<TKey,TValue> interface which provides the Add(KeyValuePair<TKey,TValue>) method: IDictionary<int, string> dictionary = new Dictionary<int, string>(); dictionary.Add(new KeyValuePair<int,string>(0,”0″)); dictionary.Add(new KeyValuePair<int,string>(1,”1″));
Generally speaking, this is better accomplished with an object instead since JavaScript doesn’t really have associative arrays: var foo = { bar: 0 }; Then use in to check for a key: if ( !( ‘bar’ in foo ) ) { foo[‘bar’] = 42; } As was rightly pointed out in the comments below, this … Read more
For Python 2.x only (thanks Alex): yourdict = {} # … items = yourdict.items() See http://docs.python.org/library/stdtypes.html#dict.items for details. For Python 3.x only (taken from Alex’s answer): yourdict = {} # … items = list(yourdict.items())
Yes, like you guessed, it’s a js object with key as string and AbstractControl as values. For example: { “control1”: new Control(), “control2”: new Control() } Edit You can declare a variable to be of this type in two ways: let controls: { [key: string]: AbstractControl }; or interface ControlsMap { [key: string]: AbstractControl; } … Read more
Say you have, e.g.: $ cat my.props first: primo second: secondo third: terzo i.e. would be a .config format except that it’s missing a leading section name. Then, it easy to fake the section header: import ConfigParser class FakeSecHead(object): def __init__(self, fp): self.fp = fp self.sechead = ‘[asection]\n’ def readline(self): if self.sechead: try: return self.sechead … Read more
Depending on your version: Python 2.x: for key, val in PIX0.iteritems(): NUM = input(“Which standard has a resolution of {!r}?”.format(val)) if NUM == key: print (“Nice Job!”) count = count + 1 else: print(“I’m sorry but thats wrong. The correct answer was: {!r}.”.format(key)) Python 3.x: for key, val in PIX0.items(): NUM = input(“Which standard has … Read more
Are you trying to do something like this? I’ve revised the example to use varying types and numbers of function parameters. package main import “fmt” func f(p string) { fmt.Println(“function f parameter:”, p) } func g(p string, q int) { fmt.Println(“function g parameters:”, p, q) } func main() { m := map[string]interface{}{ “f”: f, “g”: … Read more
