Global variable in for loop

Using Arduino Programming Questions
#1

I don’t know how to research whether I can do this or not, so any help (an answer or a site that would help) would be appreciated!

Basically, I want to do this:

Int thing1
Int thing2
int thing3

For (i=1, i++, i<3) {analogRead (Pin(i))=thing(i)}

Would this result in reading pin 1, 2 and 3, and then storing their respective values to the ints thing1, thing 2, and thing 3?

#2

Time to study ARRAYS:

No, what you need here is an array

int thing[3];

Kerias:
For (i=1, i++, i<3) {analogRead (Pin(i))=thing(i)}

be carefull with this, this code will only read inputs from pin 1 and 2, you have whether to put

i<=3

, or

i<4
#4 
For (i=1, i++, i<3)

That is wrong for a couple of reasons. Don’t capitalize for, and it should be

(i = 1; i < 3; i++)

initialize, compare, increment is the order.

A short sketch to illustrate using arrays.

int thing[3];
const byte pins[] = {A1, A2, A3};

void setup() 
{
  Serial.begin(9600);
  
  for(int i = 0; i < 3; i++)
  {
    thing[i] = analogRead(pins[i]);
    
    Serial.print(" Thing ");
    Serial.print(i);
    Serial.print("  =  ");
    Serial.println(thing[i]);    
  }
  Serial.println();  
}

void loop() 
{

}

Also

thing[i] = analogRead(Pin[i]);

Thank you all so much for the help! I'll definitely work on fixing my grammar and using arrays, sorry it's been quite some time since I've used Arduino
