Counting up the value and performing calculation using LCD Arduino - while-loop

Question

I am new to Arduino programming. My condition is I want to count up a value of i from 0 using while loop. At the same time, a calculation, b is needed to be performed continuously when counting up the value. However, the counting start from 90 instead of start from 0 when the calculation b is performing. Can anyone can help me on it? Thanks.
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
lcd.begin(20, 4);
}
void loop() {
int i;
while (i>=0){
i++;
lcd.setCursor(1,1);
lcd.print("b");
lcd.setCursor(3,1);
lcd.print(i);
delay(1000);
int c;
c = i + 2;
lcd.setCursor(1,2);
lcd.print(c);
delay(1000);
}
}

Answer 1

First of all your code should not even compile as b is not declared.
You initialize i with 0. So while (i>0) is never the case.
If you fix both you end up in an infinite loop. Not sure if you want that as there is some code after the while loop.
So pick a limit for i and use that in a for loop.
If you want to use a while loop make sure your loop condition is true >=0
You also might want to add a delay as otherwise your values change way too fast for you to see.
