Blok sxema

n! ni hisoblaydigan funksiya tuzamiz. n!=1•2•3•…•n;

K=Fact(n)
Asosiy dasturda

orqali qism dasturga(fumsiyaga) murojaat qilamiz.

Misol 1:

F(x, y) =

Z=F(a, b)+F(a/b, F(a², b²))

a va b sonlari berilgan.

F(x, y)
Z ning qiymatini toppish kerak.

if (x+y < 0)

R = x*x + y*y;

else

R = sqrt(x+y);

int main() {

double Z = F(a, b)+F(a/b, F(a*a, b*b));

Misol2

To’rtburchakning tamonlari va bitta diagonali berilgan. Uning yuzasini topuvchi dastur tuzing.

Yechimi:

To’rtburchak yuzasi diagonal ajratgan tamonlari (a, b, e) va (c, d, e) bo’lgan ikkita uchburchaklar yuzalari yi’gindisiga teng.

Uchburchak yuzasini ikki marta hisoblashga lozim. Ikki marta bir xil amalni yozmaslik uchun uchburchak yuzasini topadigan funksiya tuzamiz va unga ikki marta murojaaat qilamiz.

#include

using namespace std;

double surface_traingle(int a, int b, int c) {

double p = (a+b+c) / 2.0;

double s = sqrt(p*(p-a)*(p-b)*(p-c));

return s;

}

int main() {

int a, b, c, d, e;

cin>>a>>b>>c>>d>>e;

double s = surface_traingle(a, b, e) + surface_traingle(c, d, e);

printf("%.10f", s);
