• What is a conditional operator? Ans: The conditional operator is used as an attribute of simple if-else statement. It is used to make two way decision. The general syntax of conditional operator is (Condition)? Statement 1: Statement 2; Condition should be a logical or relation expression. After evaluation if the result of condition is true then statement 1 is executed. If result of condition is false then statement 2 is executed.

• What is a switch statement? Ans: Switch statement is an alternative of if-else-if statement. It is also a conditional statement. It is used when we want to execute a block on statements from multiple blocks. The general syntax of switch statement is Switch (expression) { break; } case constant-expression: statement (s); case constant-expression: statement (s); break; default: statement(s);
