Amaliy topshiriqlar

Berilganlar: x=12.3x10^-1, y=15.4, z=0.252x10³,

class Program {
public static void Main (string[] args) {
double x, y, z;
Console.WriteLine("x = ");
x = double.Parse(Console.ReadLine());
Console.WriteLine("y = ");
y = double.Parse(Console.ReadLine());
Console.WriteLine("z = ");
z = double.Parse(Console.ReadLine());
double a = -1/(Math.Sin(Math.PI*z/180));
double g = Math.Pow(y, x+1)/(Math.Pow(Math.Abs(y-2), 0.33)+3)+ (x+y/2)*Math.Pow(x+1, a)/(2*Math.Abs(x+y));
Console.WriteLine("S = " + g);

Hisoblashga doir sodda masalalar

Amaliy topshiriqlar
Noldan farqli berilgan R₁, R₂, R₃ elektr qarshiliklari uchun R₀ hisoblansin. Bunda: .

class Program {

public static void Main (string[] args) {

double R1, R2, R3;

Console.WriteLine("R1 = ");

R1 = double.Parse(Console.ReadLine());

Console.WriteLine("R2 = ");

R2 = double.Parse(Console.ReadLine());

Console.WriteLine("R3 = ");

R3 = double.Parse(Console.ReadLine());

if(R1 != 0 && R2 != 0 && R3 != 0){

double R = 1/(1/R1 + 1/R2 + 1/R3);

Console.WriteLine("R = " + R);

} else{

Console.WriteLine("Qarshilik noldan farqli");

}

Console.ReadKey();

}

}

Mantiqiy ifodalar

Amaliy topshiriqlar
a) k butun soni 7 ga bo‘linadi;
#include
int main() {
int k;
bool flag = false;
std::cout<<"K sonini kiriting: ";
std::cin>>k;
if(k%7==0){
flag = true;
}
return flag;
}

b) ax²+bx+c=0 tenglama haqiqiy ildizlarga ega emas;

#include

int main() {

double a,b,c;
bool flag = false;
std::cout<<"a = ";
std::cin>>a;
std::cout<<"b = ";
std::cin>>b;
std::cout<<"c = ";
std::cin>>c;
if(b*b-4*a*c < 0){
flag = true;
}
return flag;
}


d) (x,y) nuqta, markazi (1,0) nuqtada bo‘lgan r radiusli aylananing tashqarisida yotadi;

#include

int main() {
int x,y;
double r;
bool flag = false;
std::cout<<"x = ";
std::cin>>x;
std::cout<<"y = ";
std::cin>>y;
std::cout<<"r = ";
std::cin>>r;
if(1+rflag = true;
}
std::cout<return flag;
}

e) n natural soni – to‘liq kvadrat.

#include
#include

int main() {

int e;
bool flag = false;
std::cout<<"e = ";
std::cin>>e;
if(int(sqrt(e))==sqrt(e)){
flag = true;
}
std::cout<return flag;
}
