Please solve and send me explanation.

Question

When i gave my coding test i got this question and tried all the way i know but can't understand this question. If anyone can solve this then send me its explanation. The question is
#include <stdio.h>

int main() {
int x=2;
int y=5;
x+=1;
y-=x;
y++;
printf("%d",y);

return 0;
}

Answer 1

go over it line by line.

write what's the variable's expected value should be after each operation.

x+= 1; // x= 3
y-=x: // y = 5-3 = ?
y++; // y = ?

Answer 2

it's not even a question. you can just run the code to get the answer. The purpose is to understand how it is obtained.
int x = 2;
int y = 5;

x+=1 means add 1 to the value of x
x+= 1; // x= 2+1 = 3 (x was 2, now it's 3)
y-=x means subtract x from y
y-=x: // y = 5-3 = 2 (y was 5, now it's 2)
y++ means add 1 to y. it's the same as y+=1
y++; // y = 2 +1 = 3

// so what's the final value of y? 3.

printf("%d", y); //prints 3

Answer 3

John Greals ,

having a look to your `codebits` makes me believe that you should be able to understand what your mentioned code is doing and how it does work.

Answer 4

As Bob_Li said, go over it line by line - you could/should put a print after every statement and see what's happening.

Answer 5

What is your expected output?
If you can explain how to get your expected output, then we can discuss in details how it is correct or wrong.
