<span>Dragging or sizing affects only a "Selected Object." For example, an image, you need to click the image in order for you to select that image. The image is considered as an object. From the time you click on the picture, there are points visible where you can click and drag upon it nor resize.</span>
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
int perimeter(int side1, int side2, int side3){
return side1+side2+side3;
}
struct Triangle {
int side1; int side2; int side3;
};
int main(void) {
int side1, side2, side3;
cout<<"Sides of the triangle: ";
cin>>side1>>side2>>side3;
struct Triangle T;
T.side1 = side1;
T.side2 = side2;
T.side3 = side3;
cout << "Perimeter: " << perimeter(T.side1,T.side2,T.side3) << endl;
return 0;
}
