Hướng dẫn relational and logical operators in c++ - toán tử quan hệ và logic trong c ++

Các toán tử quan hệ so sánh các giá trị và trả về True hoặc FALSE Các giá trị được sử dụng với toán tử logic được chuyển đổi thành booleans trước khi được đánh giá. Đối với các giá trị số, số 0 sẽ được hiểu là sai và các giá trị khác sẽ đúng.

Toán tử logic và ví dụ là gì?Introduction to Operators in C where we got an overall idea of what types of Operators, C and C++ support, and its basic implementations. Following that, we studied Arithmetic Operators where we got a detailed understanding of the types and use of Arithmetic operators in C and C++. In this article, let’s try to understand the types and uses of Relational and Logical Operators.
 

Toán tử logic. 
Relational operators are used for the comparison of two values to understand the type of relationship a pair of number shares. For example, less than, greater than, equal to, etc. Let’s see them one by one 
 

1. Xem thảo luận Represented as ‘==’, the equal to operator checks whether the two given operands are equal or not. If so, it returns true. Otherwise, it returns false. For example, 5==5 will return true.
2. Cải thiện bài viết Represented as ‘!=’, the not equal to operator checks whether the two given operands are equal or not. If not, it returns true. Otherwise, it returns false. It is the exact boolean complement of the ‘==’ operator. For example, 5!=5 will return false.
3. Lưu bài viết Represented as ‘>’, the greater than operator checks whether the first operand is greater than the second operand or not. If so, it returns true. Otherwise, it returns false. For example, 6>5 will return true.
4. Đọc‘<‘, the less than operator checks whether the first operand is lesser than the second operand. If so, it returns true. Otherwise, it returns false. For example, 6<5 will return false.
5. Bàn luận Represented as ‘>=’, the greater than or equal to operator checks whether the first operand is greater than or equal to the second operand. If so, it returns true else it returns false. For example, 5>=5 will return true.
6. Chúng tôi đã thảo luận về việc giới thiệu các nhà khai thác trong C, nơi chúng tôi có ý tưởng tổng thể về loại nhà khai thác, hỗ trợ C và C ++ và các triển khai cơ bản của nó. Sau đó, chúng tôi đã nghiên cứu các toán tử số học, nơi chúng tôi có một sự hiểu biết chi tiết về các loại và sử dụng các toán tử số học trong C và C ++. Trong bài viết này, hãy để Lôi cố gắng hiểu các loại và cách sử dụng của các nhà khai thác quan hệ và logic. & NBSP;, the less than or equal to operator checks whether the first operand is less than or equal to the second operand. If so, it returns true else false. For example, 5<=5 will also return true.

Bằng với toán tử: được biểu thị là ‘==, bằng với toán tử kiểm tra xem hai toán hạng đã cho có bằng nhau hay không. Nếu vậy, nó trả về đúng. Nếu không, nó trả về sai. Ví dụ, 5 == 5 sẽ trả về true.
Không bằng toán tử: được biểu diễn dưới dạng ‘! =, Không bằng toán tử kiểm tra xem hai toán hạng đã cho có bằng nhau hay không. Nếu không, nó trả về đúng. Nếu không, nó trả về sai. Đó là phần bổ sung boolean chính xác của toán tử ‘==. Ví dụ, 5! = 5 sẽ trả về sai.

Các toán tử logic: & nbsp; chúng được sử dụng để kết hợp hai hoặc nhiều điều kiện/ràng buộc hoặc để bổ sung cho việc đánh giá điều kiện ban đầu đang được xem xét. Chúng được mô tả dưới đây: & nbsp; & nbsp; 
They are used to combine two or more conditions/constraints or to complement the evaluation of the original condition under consideration. They
are described below: 
 
Logical và toán tử: Toán tử ‘&&, trả về đúng khi cả hai điều kiện được xem xét đều được thỏa mãn. Nếu không, nó trả về sai. Ví dụ: A && B trả về true khi cả A và B đều đúng (nghĩa là không phải bằng 0). The ‘&&’ operator returns true when both the conditions under consideration are satisfied. Otherwise, it returns false. For example, a && b returns true when both a and b are true (i.e. non-zero).
Logical hoặc toán tử: Toán tử ‘| Nếu không, nó trả về sai. Ví dụ, A || B trả về đúng nếu một trong A hoặc B, hoặc cả hai đều đúng (nghĩa là khác không). Tất nhiên, nó trả về đúng khi cả A và B là đúng. The ‘||’ operator returns true even if one (or both) of the conditions under consideration is
satisfied. Otherwise, it returns false. For example, a || b returns true if one of a or b, or both are true (i.e. non-zero). Of course, it returns true when both a and b are true.
Toán tử không phải logic: Toán tử ‘! Trả về đúng Điều kiện được xem xét không được thỏa mãn. Nếu không, nó trả về sai. Ví dụ,! Một trả về đúng nếu a là sai, tức là khi a = 0. The ‘!’ operator returns true the condition in consideration is not satisfied. Otherwise, it returns false. For example, !a returns true if a is false, i.e. when a=0.
