Concept:In QBASIC, the
LET command assigns the value of the expression on the right side of the
= sign to the variable on the left side.
Explanation:The statement
LET X=Y−3 is an assignment statement.
First, the computer evaluates the expression
Y−3.
Then, it stores the result in the variable
X.
So,
X gets the value that is 3 less than the current value of
Y.
For example, if
Y=10, then
X becomes
10−3=7.
Therefore, the correct meaning is that
X receives the value of
Y less 3.
No type mismatch error occurs because the statement is syntactically valid.
Answer:C. the variable
X receives the value of
Y less 3.
