C++ – Convert CString into int

You can use _wtoi() or _ttoi() to convert a CString into int.

#include "atlstr.h"
#include <iostream>
using namespace std;

int main ()
{
	// Create a CString with number
	CString intStr = _T("123");

	// Convert the CString into int
	int aInt = _wtoi(intStr);

	// 123 + 123 = 246
	aInt += 123;

	// Print 246 to cout
	cout << aInt << endl;

	// Pause
	system("PAUSE");

	// Terminate the program:
	return 0;
}
