Question

Given a variable x, initially x = 0, find the value of x after the statement: if 6 + 6 = 12 then x := x + 1.

Note: ":=" means assignment

Answer 1

Isnt it 1

Answer 2

why?

Answer 3

Since 6+6=12 is a TRUE statement x=0+1=1

Answer 4

?

Answer 5

If 6+6=12 then x=x+1
^ THIS STATEMENT IS TRUE so, x=0+1

Answer 6

why x = 0 + 1?

Answer 7

because the initial value of x is 0

Answer 8

so it's just substitution?

Answer 9

Yes.......... x will be initial value of x +1

Answer 10

then what's the purpose of 6 + 6 = 12?

Answer 11

Its the given condition........ we do x=x+1 only if the given condition is TRUE

Answer 12

what if it's false?

Answer 13

The value of x will not increase by 1

Answer 14

That means we wont do x=x+1

Answer 15

so what will be done?

Answer 16

nothing as nothing said to be done if the condition is FALSE

Answer 17

like x will not be incremented, it will remain 0.
u learning programming?

Answer 18

couldn't x be any value because according to conditional statement.. if p is false then p->q is true for any truth value of q

Answer 19

isn't this related to conditional statements?

Answer 20

and @hartnn since it's in the math section...this is just discrete mathematics
