Question

Үшбұрыш қабырғалары a,b,c.Үшбұрыштың периметрін (P) есептейтін программа құрыңыз.

Answer 1

1. #include <iostream>
2. #include <cmath>
3. using namespace std;
4. int main(){
5. double x1,y1,x2,y2,x3,y3,a,b,c,P,p,S;
6. cout << "Vvedit koordinati pervoy vershini (x1, y1): ";
7. cin >> x1 >> y1;
8. cout << "Vvedit koordinati vtoroy vershini (x2, y2): ";
9. cin >> x2 >> y2;
10. cout << "Vvedit koordinati tretey vershini (x3, y3): ";
11. cin >> x3 >> y3;
12. a = sqrt(pow((x1-x2),2)+pow((y1-y2),2));
13. b = sqrt(pow((x1-x3),2)+pow((y1-y3),2));
14. c = sqrt(pow((x2-x3),2)+pow((y2-y3),2));
15. P = a+b+c;
16. p = P/2;
17. S = sqrt(p*(p-a)*(p-b)*(p-c));
18. cout << "Perimetr: " << P << "." << endl;
19. cout << "Ploshyad': " << S << "." << endl;
20. return 0;
21. }
