using namespace std;

void ishora(int a,int b)

{

return (a * b < 0) ? 1 : 0;

}

int main()

{

int n,a,b,s=0;

cout << "n = "; cin >> n;

cin >> a;

for(int i = 2; i <= n; i++)

Agar Uchburchak() funksiyasi birorta uchlik uchun true qiymat qaytarsa, shu uchlikdan hosil bo‘lgan uchburchakning yuzasini hisoblovchi haqiqiy turdagi Uchburchak_Yuzasi() funksiya tuzilsin.

#include

#include "cmath"

using namespace std;

bool Uchburchak(float a,float b,float c)

p /= a; q /= b;

cout << "natija = " << p << "/" << q;
