There is valgrind on Linux. What tools does it have on windows ??

Method:

Stdafx. h:

# DEFINE _ crtdbg_map_alloc

# Include <stdlib. h>

# Include <crtdbg. h>

_ The definition of crtdbg_map_alloc must be added, so that you can clearly see which file line has a memory leak;

Add the following after # include of each CPP file in the project:

# Ifdef _ debug

# Define new debug_new

# Endif

Add

_ Crtsetdbgflag (_ crtdbg_alloc_mem_df | _ crtdbg_leak_check_df );

This statement automatically calls _ crtdumpmemoryleaks when the program exits.

Problems:

According to the "method", but the compilation shows: Error c2065: "debug_new": Undeclared identifier

Solution: add the include <afx. h> header file because debug_new is defined in the header file.
.

Result:

Output Window Display

Detected memory leaks!
