Сымды және сымсыз желілердің айырмашылығы​

ответ: сымсыз желиде WPAN, WLAN, BWA,

Ал сымды желиде кабель мен орналаскан

Объяснение:

#include <iostream>

#include <math.h>

using namespace std;

void triangle_stats(double A, double B, double C, double* area, double* perimeter);

int main()

{

double A, B, C, S, P;

cin >> A >> B >> C;

triangle_stats(A, B, C, &S, &P);

cout.setf(ios::fixed);

cout.precision(6);

cout << "S = " << S << endl << "P = " << P << endl;

return 0;

}

void triangle_stats(double A, double B, double C, double* area, double* perimeter)

{

*perimeter = A + B + C;

double P2 = *perimeter / 2.0;

*area = sqrt(P2 * (P2 - A) * (P2 - B) * (P2 - C));

}

#include <iostream>

using namespace std;

bool is_point_in_circle(double x, double y, double xc, double yc, double r);

int main()

{

double x, y, xc, yc, r;

bool result;

cin >> x >> y >> xc >> yc >> r;

result = is_point_in_circle(x, y, xc, yc, r);

if (result) cout << "YES";

else cout << "NO";

return 0;

}

bool is_point_in_circle(double x, double y, double xc, double yc, double r)

{

if ((x - xc) * (x - xc) + (y - yc) * (y - yc) < r * r) return true;

return false;
