Chapter 9 Strings Visual C++ and MFC Fundamentals

CExerciseDoc* pDoc = GetDocument();

ASSERT_VALID(pDoc);

char Make[] = "Ford ";

int LengthMake = strlen(Make);

char Model[] = "Explorer";

int LengthModel = strlen(Model);

char *Car = strncat(Make, Model, 3);

int LengthCar = strlen(Car);

pDC->TextOut(10, 20, Make, LengthMake);

pDC->TextOut(10, 40, Model, LengthModel);

pDC->TextOut(10, 60, Car, LengthCar);

}

The string class provides its own mechanism to add two strings. It uses the addition

operator. To do this, simply add one string value or variable to another string value or

variable and assign the result to the target string variable. Here is an example:

void CExerciseView::OnDraw(CDC* pDC)

{

CExerciseDoc* pDoc = GetDocument();

ASSERT_VALID(pDoc);

string Make = "Ford ";

string Model = "Explorer";

string Car = Make + Model;

int LengthCar = Car.length();

int LengthMake = Make.length();

int LengthModel = Model.length();

pDC->TextOut(10, 10, Make.c_str(), LengthMake);

pDC->TextOut(10, 30, Model.c_str(), LengthModel);

pDC->TextOut(10, 50, Car.c_str(), LengthCar);

}

Alternatively, to add two strings, you can call the append() method. It comes in various

versions as follows:

basic_string& append(const E *s);

basic_string& append(const E *s, size_type n);

basic_string& append(const basic_string& str,

size_type pos, size_type n);

basic_string& append(const basic_string& str);
