Chapter 2.LC, Problem 1RQ
Program Description Answer
The statement lblTotal.Text = Val(txtQuantity.Text+3) does not calculate properly.
Hence, the correct answer is option “C”.
Expert Solution & Answer
Explanation of Solution
Evaluate the statement
Assignment statement is the type of instruction that assigns a value to the property of the object during the run time.
Syntax of an assignment statement:
Object.property = expression
Object and property are the name of the object and property where the expression is to be stored.
Either the numbers, letters, special characters, property of the control, or value, can act as an expression.
In the given statements, the following assignment statement does not calculate correctly:
lblTotal.Text = Val(txtQuantity.Text +3)
The Val(txtQunatity.Text+3) function concatenates both the values since ‘+’ sign acts as a concatenate operator inside the Val() function.
Therefore, “the statement lblTotal.Text = Val(txtQuantity.Text+3) concatenates the values instead of text conversion and stores it in the destination”.
