Boolean expression
A logical test is any value or expression that can be evaluated as being true or false.

true
true.
False. The statement is not true if either of the numbers is 0 or negative.
The NOT operator. E.g., NOT TRUE evaluates to FALSE while NOT FALSE evaluates to TRUE.
In C, any non-zero expression is true and any zero expression is false.
The question contains an expression - not an equation nor an inequality. An expression cannot be true or false.
The 'while' statement evaluates its expression at the beginning of the loop, while a 'do while' statement evaluates its expression at the end of the loop. The 'while' statement might execute no times. The 'do while' statement will execute at least one time. It depends on what you want to do, and on how you want to use the side effects, if any, of the expressions in the expression. (Before or after)
To ensure that each and every comparison criteria is true, you would use the logical AND operator (&& in many programming languages, or AND in SQL). This operator evaluates to true only if all the conditions it connects are true. If any single condition is false, the entire expression evaluates to false.
an identity? maybe a tautology? Comment by mgately: In the field of discrete mathematics (simplified the study of logic) any expression which always evaluates to true is in fact called a tautology. While less cool sounding, an expression which always evaluates to false is just called a contradiction.
In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.
In Java, a condition is an expression that evaluates to a boolean value, either true or false. Conditions are commonly used in control flow statements like if, while, and for loops to determine the execution path of the program. For example, in an if statement, the code block will execute only if the condition evaluates to true. Conditions can involve comparison operators (e.g., ==, !=, <, >) and logical operators (e.g., &&, ||, !).
The constant condition referred to in programming is typically represented by a Boolean expression that evaluates to either true or false. This condition is used to control the flow of a program by determining whether a particular block of code should be executed.
If is a keyword that introduces a conditional expression. If the expression evaluates true, the statement or statement block that follows is executed, otherwise control is passed to the line following the statement or statement block, which may be another conditional expression. if( expression_1 ) { // do something when expression_1 is true } else if( expression_2) { // do something when expression_1 is false but expression_2 is true } else { // do something when both expression_1 and expression_2 are false }
The AND operator is a logical operator that evaluates two or more conditions and returns true only if all conditions are true. In programming and mathematics, it is often used to combine boolean expressions. For example, in the expression "A AND B," the result is true only when both A and B are true; if either is false, the result is false. This operator is commonly used in search queries, conditional statements, and decision-making processes.
Syntax:if (expression)statement;[elsestatement;]The expression must evaluate to a boolean value, where zero is false and all non-zero values are true. The statement (including the optional else statement) may be simple or compound, and may include a nested if statement. When the expression evaluates true, the first statement is invoked. If an else statement is provided, it is only executed when the expression evaluates false. After the appropriate statement is invoked, execution passes to the statement that immediately follows the entire if statement.
