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

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
Proof Table
# 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
