Heap exception detection-MS-Visual Studio

• when applying for a heap space from the system, although the programmer does not know the data structure of the heap space, but the system or something (Microsoft can know) knows, so if we need to check the usage exceptions of the heap, we need to use the mechanism provided by Microsoft to check the normal use of the heap, in this way, we can find the illegal use of the heap in the program process and ensure the high quality of our program!
• the most important function is _ crtcheckmemory () : this function is easy to use. You can call it at the beginning and end of the Code to test the heap exception. The example is as follows:

  #include 
       
         # include 
        
          # include 
         
           # include 
          
            struct TVT {Inti; charc; chara [] ;}; void test () {char * P = new char [4]; Assert (_ crtcheckmemory ()); strcpy (P, "12345"); Assert (_ crtcheckmemory ();} int main () {test (); Return 0 ;} 
          
         
        
       

  
  
• An exception is displayed in the running result. If you select ignore, the following error is displayed:

   // assertion failed: _ crtcheckmemory (), file E: \ code \ Win32 \ test1 \ main. CPP, line 17
