I am new to Visual Studio (C++).
Can I write normal C++ program without using MFC, can I call system calls without using CreateProcess function (that is very difficult for me).
Can you please give the way?

Which programming language are you using C++, C# or VB.Net?

The question does not make any sense. Using CreateProcess is not a system call. You call this method itself, and this is a system call, but the result of this call is execution of some process, and this process is not a system call. System calls are basically used by linking system DLLs to your application and calling methods from these DLLs. It actually happens in each and every program, otherwise it could not have any effect like output of the results.

You can use one of these[^] functions.

SHELLEXECUTEINFOW execInfo;
ZeroMemory(&execInfo, sizeof(execInfo));
execInfo.cbSize = sizeof(execInfo);
execInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
execInfo.nShow = SW_SHOWNORMAL;
execInfo.lpFile = L"test.exe";
ShellExecuteEx(&execInfo);

I stopped using MFC a few years ago and am happy about it. Answer #3 is good. If you are interesting in multi-threading you can use CreateThread, C++/CLI, or a number of multi-threading libraries.

You should NEVER use CreateThread(), and C++/CLI has nothing to do in this context.

.NET (e.g. C++/CLI and C#) have multi-threading options and the ability to create processes and threads with relative ease, although using managed code has a performance hit...

When you create a new C++ project in Visual Studio you can see many different kinds that you can create.
Only those names as using MFC uses it.
Other types do not.
So it is definitely possible to write programs without using MFC.
MFC simplifies many tasks, that's all.

CreateProcess is an API that helps to create a new process from withing your executing process.
It is very similar to fork() in unix.
There is no mandate that you have to call this API.

If you want to start another process from within your process you can use CreateProcess or ShellExecute or ShellExecuteEx or system.
