Hey guys,

im new to processing.. im just trying to figure out how to find the value of something when it is executed

for example:

int result = 5;

for (int i =7; i = 20; i +=2) {

result = result + 1;

}

How do you work this out.. ?

Please help..

As it is, the loop is useless, it says

start with i = 7

check to see if i = 20

add 2 to i

The addition of one character (or replacement) makes it make sense

for(int i = 5; i <= 20; i += 2)

now says

start with i = 5

check to see if i <= 20

add 2 to i

Adding println() to the full loop

int result = 5;
for (int i = 7; i < 20; i +=2)
{
result = result + 1;
println("i = " + i +" result = "+ result);
}

should give

i = 7 result = 5

i = 9 result = 6

i = 11 result = 7

i = 13 result = 8

i = 15 result = 9

i = 17 result = 10

i = 19 result = 11

BTW, not all of us are guys!
