Question

Write an if-else statement for the following: if barcode check digit is not equal to 6, execute group id:

a) if (check_digit != 6) executeGroupId();
b) if (check_digit == 6) executeGroupId();
c) if (check_digit > 6) executeGroupId();
d) if (check_digit < 6) executeGroupId();

Answer 1

The correct if-else statement to execute a group ID when the barcode check digit is not equal to 6 is: 'if (check_digit != 6) executeGroupId();'. This uses the '!=' operator to check for inequality.

Step-by-step explanation:

The if...else statement executes a statement if a specified condition is truthy. If the condition is falsy, another statement in the optional else clause will be executed. The correct if-else statement for the scenario where you need to execute a group ID if the barcode check digit is not equal to 6 is: a) if (check_digit != 6) executeGroupId();

The other options provided do not accurately represent the given condition because they either check for equality, greater than or less than conditions contrary to what is required. Here, the != operator is used to check if the value is 'not equal' to 6. Upon finding the check digit is not equal to 6, the function executeGroupId() will be called. If the check digit is equal to 6, nothing will happen, as the else part is not defined.
