Ikki nuqta orasidagi masofani hisoblab beradigan funksiya tuzing.
- nomi:
distance - parametrlari: int aX, int aY, int bX, int bY
- qaytarishi: shu ikki nuqta orasidagi masofani float sifatida qaytaradi. Answer:
#include <iostream>
#include <cmath>
using namespace std;
float distance(int aX, int aY, int bX, int bY)
{
int a= aY - bY;
int b= aX - bY;
int cKvadrat = a*a + b*b;
int c = sqrt(cKvadrat); //square root
return c;
//return sqrt(pow(aY - bY,2)+ pow(aX - bY,2))
}
int main()
{
cout << distance(5,6,2,2);
return 0;
}

Berilgan nuqta aylana ichidami yo'qmi aniqlaydigan funksiya tuzing.
- nomi: pointIsInCircle
- parametrlar:
- aylana markazini anglatuvchi int cX, int cY
- aylana radiusini anglatuvchi int cRadius
- nuqta koordinasini anglatuvchi int pX, int pY
- qaytarishi: berilgan nuqta aylana ichida bo'lsa
trueyo'qsafalseqaytaradi. yuqorida yaratilgan distance funksiyasidan foydalaning.
Answer:
#include <iostream>
#include <cmath>
using namespace std;
float distance(int aX, int aY, int bX, int bY)
{
int a= aY - bY;
int b= aX - bY;
int cKvadrat = a*a + b*b;
int c = sqrt(cKvadrat); //square root
return c;
//return sqrt(pow(aY - bY,2)+ pow(aX - bY,2))
}
bool pointIsInCircle(int cX, int cY, int cRadius, int pX, int pY)
{
return distance(cX, cY, pX, pY) < cRadius;
}
int main()
{
cout << pointIsInCircle(3,3,2,5,5) << endl;
return 0;
}
