Use substr. The first value is the string, the second is the starting character position (in your case, 2 is in position 0, the – is in position 1, etc.). You can also specify a length as a third parameter if you so choose. $s = substr($str, 2); solved PHP: get every character of a … Read more
What you are looking for is technically impossible. To return false from the original function, you have to explicitly use the return statement – no going around that. In your example, you will need to use: return require_parameters( $first_parameter, $second_parameter ); But the definition of require_parameters will have to use varargs as you never know … Read more
Why do you think this a loadmat object not having a dictionary?

Well, we essentially need to do 2 things. First we need the objects. Then we need a way to access them from the C# script, and call the SetActive method. At the main menu, click on GameObject -> Create empty. Name the game object something appropriate. Like CubesThatWillAppear. At the main menu, click on GameObject … Read more
Don’t override the paint() method. Custom painting is done by overriding the paintComponent() method of a JPanel (or JComponent) and then you add the panel to the applet Don’t invoke repaint() from any painting method. This will cause an infinite loop. Don’t use sleeping code inside a painting method. If you want animation then use … Read more
No. Hash table based implementation of the Map interface. This implementation provides all of the optional map operations, and permits null values and the null key. (The HashMap class is roughly equivalent to Hashtable, except that it is unsynchronized and permits nulls.) This class makes no guarantees as to the order of the map; in … Read more

It’s more than likely setting the byte to 0xFF (which is equal to -1 as a signed byte). solved In c++ what does this mean: for string n and int l n[l]=-1; [closed]
What you said, is quite a project, not a question. I’d rather to study more about the similar projects and ask about some details in here. Although I could give you some hints: 1-Do a suitable thresholding on your image, like Otsu method (with a little change in the threshold value if it’s needed). 2-On … Read more
It is because a slice is already a pointer (https://golang.org/ref/spec#Slice_types). So to set a pointer to a slice is setting a pointer to a pointer. So just remeber if you are dealing with slices they are pointers to arrays. More information how the slices are used as a pointer are here: https://golang.org/doc/effective_go.html#slices solved Weird behavior … Read more

You can use C++11 type traits for this (or, if you don’t have C++11 yet, use type traits from Boost): #include <type_traits> template <typename K, bool special = std::is_same<K, char>::value || std::is_same<K, int>::value> struct A { // general case }; template <typename K> srtuct A<K, true> { //int-or-char case }; 5 solved Template Specification
