C ++ dasturlash tilida mantiqiy operatorlari:

&& va (and)

|| yoki (or)

Chinlik jadvallari ko'pincha murakkab mantiqiy ifodaning barcha mumkin bo'lgan qiymatlarini aniqlash uchun ishlatiladi.

• Biz barcha mantiqiy iboralar uchun ustunlar qilamiz
• Har bir satr kirish qiymatlarining bitta to'plamini aks ettiradi

Murakkab mantiqiy iFODalar

((17 < 42) && (42 < 17)) is false, chunki ikkalasi yarmi false

• ((17 < 42) && (42 < 17)) is false, chunki ikkalasi yarmi false
• ((17 <= 42) || (42 <= 17)) is true, birinchi yarmi true
• Haqiqiy tipli o’zgaruvchining qiymati x = 3.14 va y = 7.89 teng bo’lganda
• ((x < 4) && (y < 8)) is true, chunki ikkalasi ham true
• ((x > 3) && (y > 8)) is false, chunki ikkalasi yarmi false
• ((x < 4) || (y > 8)) is true, chunki birinchi yarmi true
• ((x < 3) || (y < 8)) is true, chunki ikkinchi yarmi true
• ((x > 4) || (y > 8)) is false, chunki ikkalasi ham false

Not operatori

• C++ dasturlash tilida not operatori har qanday mantiqiy ifodani teskarisiga aylantiradi
• not true = false
• not false = true
• not operator -> ! Belgi bilan yoziladi

NOT operatori

• Butun qiymatli a = 7 va b = 3 o’zgaruvchilar berilgan bo’lsin.
• (a > b) is true !(a > b) is false
• (a <= b) is false !(a <= b) is true
• (a == b) is false !(a == b) is true
• (a != b) is true !(a != b) is false

NOT operatoriga misollar

• !(a < b) ga o’xshax (a >= b)
• !(a <= b) ga o’xshax (a > b)
• !(a > b) ga o’xshax (a <= b)
• !(a >= b) ga o’xshax (a < b)
• !(a == b) ga o’xshax (a != b)
• !(a != b) ga o’xshax (a == b)
