Answer 1

Which of the following produces a result ?1.operator2. query 3.expression and 4.none of these

Option 4. is correct

Answer 2

The correct response to the given question is Option 3: Expression.

• Expression is a set of operands, operators, and variables that are expressed in a logical or sequential order to produce a result or value.
• The operands are the numerical values that will be computed. The symbols that carry out mathematical operations between two or more operands are known as operators.
• When all of this is put together in a computer, it creates an expression that, when written, gives a result.
• For example, A - B * C = Result
• Where "A - B * C" is called expression
• A, B, and C are the operands with a different value, and "-" and "*" is called the operator.
• The operator alone that does not have a numerical value along with it does not provide a result unless it is expressed in the correct value using variables and constants.
• A query is a sequence of commands that specify what information or data to obtain from a particular source of data as well as how the data should be structured. A query is different from the results it generates.
• As a result, in this context of obtaining results, expression is the proper answer.
