Assertions are used as part of a logical argument that a program is correct.

Question
Assertions are used as part of a logical argument that a program is correct. Suppose that this assertion: (j+i == n) && (2i > 10)is required to be true after the assignment statement i = i+1;What is the best description of what must be true before the assignment statement to achieve that outcome:(j+i == n-1) && (2i > 8)(j+i == n+1) && (2i > 12)(j+i == n+1) && (2i > 10)(j+i == n+1) && (2i > 8)(j+i == n-1) && (2i >= 10)
Solution
The best description of what must be true before the assignment statement to achieve that outcome is: (j+i == n-1) && (2*i > 8)
Here's the step by step explanation:
-
The assignment statement is i = i+1; which means the value of i is increased by 1.
-
For the assertion (j+i == n) && (2*i > 10) to be true after the assignment, we need to consider the increased value of i.
-
For the first part of the assertion (j+i == n), before the assignment, the sum of j and i should be equal to n-1. This is because i will be increased by 1 after the assignment, making the sum equal to n.
-
For the second part of the assertion (2i > 10), before the assignment, 2i should be greater than 8. This is because i will be increased by 1 after the assignment, making 2*i greater than 10.
-
Therefore, the condition that must be true before the assignment is (j+i == n-1) && (2*i > 8).

An assertion is a command of the form assert(boolean_expression) that prints an error and exits the program if the boolean expression is false.
