Answer to Question #200368 in C++ for Ahmed Ali

Question

Write a program using class “math”. Pass three values as arguments to the constructor of the class and initialize these values to data members x&y&z of the class . the class should have the following member functions-: o One member function ‘max’ to find and return the maximum of three numbers. o One member function ‘sum’ to compute and return the sum of three numbers. o One member function ‘factorial’ to find the minimum number of three numbers and computes its factorial and return to calling function.

	}
	//One member function ‘max’ to find and return the maximum of three numbers
	int max(){

	}
	// One member function 'sum' to compute and return the sum of three numbers.
	int sum(){
		return x + y + z;
	}
	//One member function 'factorial' to find the minimum number of 
	//three numbers and computes its factorial and return to calling function.
