I tried this code in code block and I got the output as 3. But here, the compiler says 4. Why?

I tired this;
#include<stdio.h>
int main()
{
int i=3;
i = i++;
printf("%d\n%d", i,i++);
return 0;
}
______________
The output is
3
4
Can anyone explain how i++ became 3?
#include<stdio.h>
int main()
{
int i=3;
i = i++;
printf("%d\n%d", i,i++);
return 0;
}
______________
The output is
3
4
Can anyone explain how i++ became 3?

Answer will be 3, not 4. Just compile it on another online compiler. And conceptually also it should be 3.

int i = 3;
i = 3+3;
i = 6;
i++;
i = 7;
i++;
i = 8;
Finally i = 8 will be print;
i = 3+3;
i = 6;
i++;
i = 7;
i++;
i = 8;
Finally i = 8 will be print;

Can anyone solve my doubt? What is the output of this?
i = i++ + i++;
printf("%d",i);
i = i++ + i++;
printf("%d",i);

Answer must be 3, because post increment operator assigns value first and then incremented.
In DEV CPP while I run above program answer is 3.

For that question some compiler will give different answer like Dev C++.
Is giving 3 instead of 4 because when a single expression causes the same object to be modified then inspected the behavior is undefined. In this case I = i++;
Here variable I is being modified and then it is being used by the compiler. That's why answer 4 is coming here.

@Suraj.
Answers will be 4, 3 in post increment value will be assigned later incremented so j=3 and i=4.
