|---|---|
| The _____ statement causes the program flow to exit prematurely from the body of the loop statement. continue break else else if | break |
| The ______ loop executes a given statement or block of statements repeatedly as long as the value of the expression is true. while for switch case | while |
| The break statement causes the program flow to skip over and jump to the end of the loop body, and then return the control to the loop control statement. false true | false |
| arithmetic operator is a mathematical function that takes two operands and performs a calculation on them. false true | true |
| It divides left operand with the right operand and assign the result to left operand. -= *- += /= | /= |
| unary operator is an operator used to perform bitwise operations on bit patterns or binary numerals that involve the manipulation of individual bits true false | false |
| It subtracts right operand from the left operand and assign the result to left operand. += *- -= /= | -= |
| The ________ identifies any valid statement to which control must be transferred break label continue lbl | label |
