Object Oriented Programming Practical 6
Question 1
Write a C++ program to calculate area of Rectangle using Inline function.
rectangle.cpp
C
#include <iostream.h>
#include <conio.h>
inline int calculateArea(int length, int width)
{
return length * width;
}
void main()
{
int length, width;
cout << "Enter the length of the rectangle: ";
cin >> length;
cout << "Enter the width of the rectangle: ";
cin >> width;
int area = calculateArea(length, width);
cout << "The area of the rectangle is: " << area << endl;
getch();
}
Output
Question 2
Write a C++ program to create a class "Number" having data members n1 and n2 and perform mathematical operations like addition, subtraction, multiplication and division on two numbers using inline functions.
number.cpp
C
#include <iostream>
#include <conio.h>
class Number
{
private:
int n1, n2;
public:
void accept()
{
cout<<"Enter number 1: ";
cin>>n1;
cout<<"Enter number 2: ";
cin>>n2;
}
inline int add()
{
return n1 + n2;
}
inline int subtract()
{
return n1 - n2;
}
inline int multiply()
{
return n1 * n2;
}
inline float divide()
{
if (n2 != 0)
{
return (float)n1/n2;
}
else
{
cout << "Error: Division by zero is not allowed." << endl;
return 0;
}
}
};
int main() {
int num1, num2;
Number num;
num.accept();
cout << "Addition: " << num.add() << endl;
cout << "Subtraction: " << num.subtract() << endl;
cout << "Multiplication: " << num.multiply() << endl;
cout << "Division: " << num.divide() << endl;
getch();
return 0;
}
Output
