value_if_true : value_if_false. The condition is evaluated true or false as a Boolean expression. On the basis of the evaluation of the Boolean condition, the entire expression returns value_if_true if condition is true, but value_if_false otherwise. Usually the two sub-expressions value_if_true and value_if_false must have the same type, which ...
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
The statement A ∨ B is true if A or B (or both) are true; if both are false, the statement is false. n ≥ 4 ∨ n ≤ 2 ⇔ n ≠ 3 when n is a natural number. ⊕ ...
A string is considered true if it contains at least one non-whitespace character (thus, for example, the #if function interprets the strings "0" and "FALSE" as true values, not false). Any string containing only whitespace or no characters at all will be treated as false (thus #if interprets " " and "", as well as undefined parameters, as false ...
The biconditional is true in two cases, where either both statements are true or both are false. The connective is biconditional (a statement of material equivalence), [2] and can be likened to the standard material conditional ("only if", equal to "if ... then") combined with its reverse ("if"); hence the name. The result is that the truth of ...
True or False Questions About History. 96. Coca-Cola was the first soft drink in the United States. Answer: False – it was Dr Pepper. 97. Erik the Red was the uncle of famous explorer Leif Erikson.
The result of R is TRUE (1) if exactly one of its arguments is TRUE, and FALSE (0) otherwise. All 8 combinations of values for x , y , z are examined, one per line. The fresh variables a ,..., f can be chosen to satisfy all clauses (exactly one green argument for each R ) in all lines except the first, where x ∨ y ∨ z is FALSE.
However, in Microsoft Excel, subroutines can write values or text found within the subroutine directly to the spreadsheet. The figure shows the Visual Basic code for a subroutine that reads each member of the named column variable x , calculates its square, and writes this value into the corresponding element of named column variable y .
