How to draw a circle and then when keyPressed, draw another circle etc - processing

Question

I am learning how to code in Processing 4.
I am trying to make a code where when keyPressed() is clicked, one circle is drawn then when the button is pressed again, the first circle remains and then a second circle is drawn but with extent increased by 10, then the key pressed for a final time (3) and the third circle is drawn with the extent increased by 3 then it stops producing more circles.
This is the code I have so far but I am confused on how to approach it. Right now, the first circle just increases in size and it doesn't draw a second one. How do I draw 3 circles, one once keyPressed()?
int sizeIncrease = 10;
int initialSize = 70;
void setup() {
size(500, 500);
}
void draw() {
background(0);
stroke(255,0,0);
strokeWeight(25);
fill(255);
pushMatrix();
translate(20, 50);
circle(width/2, height/2, initialSize);
popMatrix();
}
void keyPressed() {
initialSize += sizeIncrease;
}

Answer 1

Add a variable count. Increment the variable when a key is pressed and draw the circles in a for-loop:
int sizeIncrease = 10;
int initialSize = 70;
int count = 1;
void setup() {
size(500, 500);
}
void draw() {
background(0);
noFill();
stroke(255);
pushMatrix();
translate(20, 50);
for (int i = 0; i < count; i++) {
circle(width/2, height/2, initialSize + i*sizeIncrease);
}
popMatrix();
}
void keyPressed() {
count ++;
}

Answer 2

int sizeIncrease = 10;
int initialSize = 70;
int count = 1;
void setup() {
size(500, 500);
}
void draw() {
background(0);
noFill();
stroke(255);
pushMatrix();
translate(20, 50);
for (int i = 0; i < count; i++)
{
circle(width/2, height/2, initialSize + i*sizeIncrease);
**if(i == 1)
{
sizeIncrease = 3;
}**
}
popMatrix();
}
void keyPressed() {
count ++;
}
