I am new to IDE and if I have to be honest coding in general.
//Survey Q2 unsolved
const int LED1 = 13;
const int LED2 = 12;
const int B1 = 2;
const int B2 = 4;
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
// [INSERT LINE HERE]
void setup() {
pinMode(LED1, OUTPUT);
pinMode(B1, INPUT);
pinMode(LED2, OUTPUT);
pinMode(B2, INPUT);
}
void loop() {
buttonState = digitalRead(B1);
if (buttonState == HIGH) {
digitalWrite(LED1, HIGH);
} else {
digitalWrite(LED1, LOW);
}
buttonState = digitalRead(B2);
if (buttonState == HIGH) {
digitalWrite(LED2, HIGH);
} else {
digitalWrite(LED2, LOW);
}
}

"exit status 1 error compiling for board Arduinio/Genuino Uno."
What else does it say?
if (buttonState == HIGH) {
digitalWrite(LED1, HIGH);
} else {
digitalWrite(LED1, LOW);
}
Hint digitalWrite(LED1, buttonState);
That's all is says and no code lines are highlighted with errors.

Click the button to copy the error messages, and paste the output here.
We need to know what step it was failing on.
Also what version of windows? What version of the IDE?

(Back at a PC)
'B1'
Arduino bites you on the butt.
Change "B1" to "button1"
IDE 1.8.6
Win 10pro
Arduino: 1.8.6 (Windows 10), Board: "Arduino/Genuino Uno"

Explanation: Do the macro expansion
From C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino/binary.h
#define B1 1
From C:\Users\rfhal\Desktop\Arduino IDE\Two_LED_on_push_buttons\Two_LED_on_push_buttons.ino
const int B1 = 2;
So, what the compiler sees is const int 1 = 2;
So, read reply #4 and implement, and all will be well.
I got it.
