Neither language C or C++ has any notion of “segments”, and not all OSs do either, so your question is inevitably dependent on the platform and compiler. That said, common implementations will treat initialized vs. uninitialized variables differently. The main difference is that uninitialized (or default 0-initialized) data does not have to be actually saved … Read more
That’s completely expected. Variables have a scope to them. If you define them inside of a control block (like an if statement), then they won’t be available outside. So, what you need to do is initialize it outside like so: $text-color: null; $background-color: null; @if $colorscheme == white { $text-color: #333; $background-color: #fff; } @else … Read more
No, there is no way to tell the JavaScript language to use hex integer format instead of decimal by default. Your code is about as concise as it gets but note that you do not need to prepend the “0x” base indicator when you use “parseInt” with a base. Here is how I would approach … Read more
Constant is the concept, the property of the variable. final is the java keyword to declare a constant variable. As other people pointed out, from a semantic/linguistic point of view the expression constant variable is an oxymoron and, as such, we could argue about its correctness. Quoting the specification, anyway, we can read A variable … Read more
I think global properties should be avoided and gradle offers you a nice way to do so by adding properties to a task: task task1 { doLast { task1.ext.variable = “some value” } } task task2 { dependsOn task1 doLast { println(task1.variable) } }
First way is function function1() { var variable1=12; function2(variable1); } function function2(val) { var variableOfFunction1 = val; // Then you will have to use this function for the variable1 so it doesn’t really help much unless that’s what you want to do. } Second way is var globalVariable; function function1() { globalVariable=12; function2(); } function … Read more
A local variable is the variable you declare in a function. A member variable is the variable you declare in a class definiton.
Here’s a way in C++11, using std::initializer_list: #include <algorithm> #include <initializer_list> template <typename T> bool is_in(const T& v, std::initializer_list<T> lst) { return std::find(std::begin(lst), std::end(lst), v) != std::end(lst); } with that, you can do: if (is_in(num, {1, 2, 3})) { DO STUFF } It is not very efficient though when not used with built-in types. int … Read more
Any use of var foo in a function will scope foo to that function. It doesn’t matter where in the function this takes place as var declarations are hoisted. Additional uses of var foo in the same function are syntactically legal but will have no effect as the variable is already scoped to that function. … Read more
