You will not see 20 on the screen because the loop is exited before 20 is used in the
body of the loop. Recall that the boolean condition was x < 20 . Once x hits 20 ,...

mod
14 is 0 because there is no remainder.
1 72
mod
35 is 32 because 1 72 7 35 ¼ 4 with a remainder of 32.
1943
mod
7 is 4 because 1943 7 7 ¼ 27 7 with a remainder ... the last example, 28 is > 12 but 28 is not < 20 , so
true and false produces false.
Tip
The logic operator
and
has to have all relational expressions around it to be true for...
... = 24 ;
x %2= =0//is24 %2= =0?
+
24 % 2
+
0==0
+
true
(Therefore, x is an even number.)
int x;
x = 17;
x %2= =0//is17 %2= =0?
+
17 % 2
+
1==0
+
false
(Therefore, x is not even and so must be odd.)
1 02 ... number (2) on the screen.
After that, x changes from 2 to 3. This pattern continues. See Figure 7.10.
Example 2
In a second example utilizing a for loop, let’s look at a list of...
... Matrix 21 1
Col 1 Col 2 Col 3 Col 4
Row 2
group [2] [1] group [2] [2] group [2] [3] group [2] [4]
Data inside 10 10 10 10
If we were to load the row manually, it would look like this:
Row Col
group [2] [1] ... value

So what happens is the outer loop holds its value, while the inner loop spins
through all its values. The entire execution of both loops looks like this:
