c++ - SDL_Surface 的无效动态表

Question

我在创建 SDL_Surface 的动态表时遇到困难。看看这段代码:

SDL_Surface **testA = new SDL_Surface *[2];
for(int i=0;i<2;i++)
    testA[i] = new SDL_Surface;
SDL_Surface* testB[2];

就我而言，TestA 和 textB 应该看起来相同。但是 Visual Studio locals 看起来像这样:

我该如何解决？

Answer 1

试试这个:

    int size=2;
    SDL_Surface** testA ; 
    testA  = new SDL_Surface*[size];  

    for (int i = 0; i < size; i++) 
    { 
      surface[i] = NULL; //  here, surface[i] is the kth pointer, not an SDL_Surface 
   // surface[i] = SDL_CreateRGBSurface ( /* set your parameters */ );
    } 


    // Of course, somewhere later in the code, you'll need to free the memory ... 
    for (i = 0; i < size; i++) 
    { 
    SDL_FreeSurface(testA [i]); 
    testA [i] = NULL; 
    } 

    delete testA ;
