Re: Android Native - How To Request Notification Permissions 1 Day Ago by Inamullah_1 Great tutorial—thanks for sharing! Just a few quick additions: Starting with Android 13 (API 33), apps must request permission for POST_NOTIFICATIONS at runtime, while older versions allow notifications by default. It’s best to check the Android version before requesting this permission to avoid unnecessary prompts. Also, remember to handle the … Re: Hi everyone, I'm David with SayItOnTheWeb 1 Month Ago by Dani … computers.

A look at the STL vector. 20 Years Ago by vegaseat The Standard Template Library (STL) vector is tempting. The burden of dimensioning an array is removed, and there are many wonderful functions to explore. The learning curve is a little steep, it will make your head swell, but in the end it's all worthwhile. Take a look at some of the code that is supposed to make programming easier.

If element of … Re: STL vector destruction 16 Years Ago by sarehu No you don't. When a vector's destructor gets called, it calls the destructors of all its elements. Re: STL vector destruction 16 Years Ago by sarehu For example, the behavior of the following two snippets is more or less the same, as far as destruction is concerned: [code] T* p = new T[3]; p[0] = x; p[1] = y; p[2] = z; delete[] p;[/code] [code] { std::vector<T> v; v.push_back(x); v.push_back(y); v.push_back(z); } [/code] Re: STL vector - deleting the last element 18 Years Ago by yesm Hmmmm.
