Hayotiy misol
Hayotiy misol
Keling, boolean qiymatlardan hayotiy misolda foydalanamiz: insonning ovoz berish uchun yoshi yetarli ekanligini aniqlaymiz.
Quyidagi misolda yosh (25) ovoz berish uchun belgilangan yosh chegarasidan (18) katta YOKI unga teng ekanligini aniqlash uchun >= taqqoslash operatoridan foydalanamiz:
Misol
int myAge = 25;
int votingAge = 18;
cout << (myAge >= votingAge); // returns 1 (true), meaning 25 year olds are allowed to vote!

Ajoyib, to‘g‘rimi? Bundan ham yaxshiroq yondashuv (endi ishimiz yurishib ketdi-ku) — natijaga qarab turli amallarni bajarish uchun yuqoridagi kodni if...else operatoriga o‘rash:
Misol
Agar myAge qiymati 18 qiymatidan katta yoki unga teng bo‘lsa, "Old enough to vote!" matnini chiqaring. Aks holda "Not old enough to vote." matnini chiqaring:
int myAge = 25;
int votingAge = 18;
if (myAge >= votingAge) {
cout << "Old enough to vote!";
} else {
cout << "Not old enough to vote.";
}
// Outputs: Old enough to vote!

Boolean qiymatlar C++ tilidagi barcha taqqoslash va shartlarning asosidir.
Shartlar (if...else) haqida keyingi bobda batafsil bilib olasiz.
