Lab # 13

You need to write a program in which the following concepts must be implemented. Write a template function name “Add” which accepts two arguments of the same type int, float, double from the user then add those arguments, return their sum and display them on the screen. Write a class named as firstClass, also write another class named as secondClass which should be nested inside the firstClass. Define a function named displayMessage inside the secondClass, this method should print the message “Inside the second class” on the screen. In the main function create the object of the secondClass and invoke the displayMessage method using the secondClass object.

Solution:

class firstClass {

public:

class secondClass { public: void displayMessage(){ cout<< " Function inside the inner class" <<endl;

template<class T> T Add (T x, T y) { return x + y;

int main() {

firstClass :: secondClass object; object.displayMessage();

int integerOne = 3, integerTwo = 5; float floatOne = 12.34, floatTwo = 894.4; double doubleOne = 1236.58, doubleTwo = 8945.685;

cout<< " Addition of Two integer Number is = " << Add(integerOne,integerTwo) <<endl; cout<< " Addition of Two floating point Number is = " << Add(floatOne,floatTwo) <<endl; cout<< " Addition of Two double Number is = " << Add(doubleOne , doubleTwo) <<endl;

return 0;
