Tomonlari bilan berilgan uchburchakning perimetri va yuzasini hisoblang

6-topshriq

1. 
   Tomonlari bilan berilgan uchburchakning perimetri va yuzasini hisoblang.
   

#include
#include

int main() {

double a, b, c;

// Tomonlarni o'qish

std::cout << "Uchburchak tomonini kiriting (a): ";
std::cin >> a;
std::cout << "Uchburchak tomonini kiriting (b): ";
std::cin >> b;
std::cout << "Uchburchak tomonini kiriting (c): ";
std::cin >> c;

// Perimetrni hisoblash

double P = a + b + c;

// Yuzani hisoblash

double S = sqrt(P * (P - a) * (P - b) * (P - c));

// Natijalarni chiqarish

std::cout << "Uchburchak perimetri (P): " << P << std::endl;
std::cout << "Uchburchak yuzasi (S): " << S << std::endl;

return 0;

}

2. 
   a, b, c sonlari berilgan. Ularning manfiylarini 2 marta oshiring, musbatlarini 2 ga bo‘ling, nolga teng bo‘lganlarini o‘zgarishsiz qoldiring.
   

#include

int main() {

int a, b, c;

// a, b, va c ni o'qish

std::cout << "a ni kiriting: ";
std::cin >> a;
std::cout << "b ni kiriting: ";
std::cin >> b;
std::cout << "c ni kiriting: ";
std::cin >> c;

// Manfiy sonlarni 2 marta oshirish

if (a < 0) {
a = a * 2;
}
if (b < 0) {
b = b * 2;
}
if (c < 0) {
c = c * 2;
}

// Musbat sonlarni 2 ga bo'lish

if (a > 0) {
a = a / 2;
}
if (b > 0) {
b = b / 2;
}
if (c > 0) {
c = c / 2;
}

// Natijalarni chiqarish

std::cout << "Natijalar: a=" << a << ", b=" << b << ", c=" << c << std::endl;

return 0;
