Suppose the application name is myapp.exe (I suppose you're writing a console application), you can type


myapp.exe 1

I appreciate your help all the time...

I work on console application and use VS.Net 2003 for all of this. So my first question is how should I give command line parameter.

How can I deal it with the following explanation. Thanks in advanced.

if it isn't static, then you have to create an instance of the class:

int _tmain(int argc, _TCHAR* argv[])
{
	// srgc - Argument counter
	// srgv - Argument vector

// Instance
	CAdd m_Add;

// Argument check
	if(argc < 2)
	{
		cout << "Less" << endl;
		return EXIT_FAILURE;	// used RTL
	}

// Select the function
	int n;
	n = atoi(argv[1]);

	switch(n)
	{
		case 1:
			//func1();
			m_Add.addNumbers();
		break;
		case 2:
			//func2();
			m_Add.diffNumbers();
		break;
		default:
			cout << "Invalid argument" << endl;
		break;
	}

	cin.get();
    return 0;
}

Did it compile (I mean is it a ANSI build)?

What can you see using the debugger?

You mean in debug mode. It seems work fine. That's why I confused. Go through step by step there.

n = atoi(argv[1]);

m_Add.addNumbers();

func.exe sum

'_tcscmp' : cannot convert parameter 2 from 'bool' to 'const char *'
