内存错误笔记

Windows has triggered a breakpoint in t.exe.

 

This may be due to a corruption of the heap, which indicates a bug in t.exe or any of the DLLs it has loaded.

 

This may also be due to the user pressing F12 while t.exe has focus.

 

The output window may have more diagnostic information.

 

这个错误发生的两个原因：

1.用delete或是free删除不是堆栈上的变量。

比如：

int n = 88;

delete n;

 

2.使用了已经delete或是free后的变量。

比如：

    char *str = (char *) malloc(100); strcpy(str, "hello"); free(str); if(str != NULL) { strcpy(str, "world"); printf(str); }
