Proof: Write Assign Const Tab 0
Let's prove the following theorem:
if the following are true:
- the line at time 0 = 1
- the tab at time 0 = 0
- statement at line 1, tab 0 =
c = 16
- 16 is constant
then the tab at time 1 = 0
Proof:
Given
1 | the line at time 0 = 1 |
---|---|
2 | the tab at time 0 = 0 |
3 | statement at line 1, tab 0 = c = 16 |
4 | 16 is constant |
# | Claim | Reason |
---|---|---|
1 | the tab at time (0 + 1) = 0 | if the line at time 0 = 1 and the tab at time 0 = 0 and statement at line 1, tab 0 = c = 16 and 16 is constant, then the tab at time (0 + 1) = 0 |
2 | 0 + 1 = 1 | 0 + 1 = 1 |
3 | the tab at time (0 + 1) = the tab at time 1 | if 0 + 1 = 1, then the tab at time (0 + 1) = the tab at time 1 |
4 | the tab at time 1 = 0 | if the tab at time (0 + 1) = the tab at time 1 and the tab at time (0 + 1) = 0, then the tab at time 1 = 0 |
