Čo je ciphertext mcq

Answer: A Explanation: The strict comparison operator returns true only if the operand are of the same type and content matches. When the switch statement is executed, the value of the expression is calculated and compared to the case labels, and looks for a case whose expressions produce the same value after evaluations (where the comparison is determined by the === operator).
