```auto

void setup() {
}
void draw() {
for (char c = char(i); c < i+58; c++)
println( i + " : " + c);
}
```
how to increase number i to 34, 35, 36, etc
thanks

Consider using i in the for loop to increment and then
`c = char(i);`
in the loop.

I leave the rest with you.

```auto
int i = 33;
void setup() {
for (int j = i; j < i+58; j++){
println( j + " : " + char(j));
}
}
void draw() {
}
```
increasing i (by using i++;) inside the for loop leads to an infinite loop. (calling it in draw as well, move it to setup() to execute it once)

you can also increase c if you like
c++ is just short for c = c + 1
```auto
int i = 33;
void setup() {
for (char c = char(i); c < char(i+58); c++) {
println( int(c) + " : " + c);
}
}
void draw() {
//
}
```
**Other way**
or use i as a secondary variable along with c
```auto
final int startAscii = 33;
void setup() {
size(333, 333);
int i=startAscii;
for (char c = char(startAscii); c < char(startAscii+58); c++) {
println( i + " : " + c);
i++;
}//for
}//func
void draw() {
//
}//func
```

```auto

void setup() {
}
void draw() {
if(i<37){i+=1}
for (char c = char(i); c < i+58; c++)
println( i + " : " + c);

This is one way to get the alphabet in lowercase and the code is easier to read. Even better, `letter <= 'z'`.
Kf
```auto
final int N_LETTERS=26;
for (char letter= 'a'; letter < 'a'+N_LETTERS; letter++) {
println( int(letter) + " : " + letter);
}
```

Hello,
What was _your_ final solution?

I hope it will be @Rai
I am interested in what _his solution_ (without referencing or cutting and pasting code) was after gleaning through this topic.

i’m ask because i don’t know what wrong with this code not because homework or something so @ForgottenCat explain to me my code wrong because put in void draw () make i in infinite loop, i ask and learn processing for my self not school or something so if i’m just copy paste from this answer i can’t get anything, i’m here to ask for learn not for copy paste @glv

Hi Rai,
processing calls (=executes) the setup only once at startup. so it is great to initize any variables etc.
draw is sort of a loop. so it executes and if its finished, it restarts at the first line after draw(){. to avoid that, you have many possibilities, like “move it to setup” or check for a condition therefore moving it in some if statement.

Hello Rai,
In your original you post you shared code and asked:

You also messaged me directly and I asked you to:

I was the first to respond…
I tried to understand what you were doing, wrote some code, and gave you some direction and references. I did not share a complete solution with you; this was very achievable by you.

Your last two posts mentioned homework and school; I did not raise this point in this topic.
The community here all stepped in to help you with a lot of examples.
I was genuinely interested in what you learned from this and _your final solution_ and I am still interested in what that is.
