Assalamu aleykum bugun sizlar bilan C++ dasturlash tilida ishlatiladigon Ternary Operator buni tarjimasi - uchlik operatori xaqida gaplashib o'tamiz.
Uchlik operator sinov shartini baholaydi va shart natijasi asosida kod blokini bajaradi.
#include <iostream>
using namespace std;
int main() {
double marks;
// take input from users
cout << "Enter your marks: ";
cin >> marks;
// ternary operator checks if
// marks is greater than 40
string result = (marks >= 40) ? "passed" : "failed";
cout << "You " << result << " the exam.";
return 0;
}
Natija:
Enter your marks: 80
You passed the exam.
Uchlik operatoridan qachon foydalanish kerak?
C++ da uchlik operatori if...else ifodalarining ayrim turlarini almashtirish uchun ishlatilishi mumkin.
Masalan, biz ushbu kodni almashtirishimiz mumkin
#include <iostream>
using namespace std;
int main() {
// Create a variable
int number = -4;
if (number > 0)
cout << "Positive Number";
else
cout << "Negative Number!";
return 0;
}
Misol uchun shuni ternaryda qilingan variant:
#include <iostream>
#include <string>
using namespace std;
int main() {
int number = -4;
string result;
// Using ternary operator
result = (number > 0) ? "Positive Number!" : "Negative Number!";
cout << result << endl;
return 0;
}
Bu erda ikkala dastur ham bir xil natijani beradi. Biroq, uchlik operatoridan foydalanish bizning kodimizni yanada o'qilishi va toza qiladi.
Eslatma: Agar natija qisqa bo'lsa, biz uchlik operatoridan foydalanishimiz kerak.
