A look at the STL vector. 19 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.

When a vector's destructor gets called, it calls the destructors of all its elements. Re: STL vector destruction 15 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 16 Years Ago by yesm Hmmmm.

Can you tell me how its not being contructed? Thanks Re: STL Vector and Malloc 12 Years Ago by wazzer225 Ah ok the line [CODE]vector< string > *u = new vector< string >(10,"test");[/CODE] is constructing a tempory object then using the assignment operator to assign to the allocated memory in which the object is uninitialized. Thanks for your answer. Re: STL Vector and Malloc 12 Years Ago by wazzer225 But in the above code I’m calling the constructor after I have used malloc: [CODE]*u = vector< string >(10,"test");[/CODE] Is it because malloc does not initialise all the bits in the memory it allocates? But i would'nt know why that would make a difference if the contructor is being called.
