I think the answer is 3. I run it on both GCC complier or turbo C compiler try it on your own.

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

Post increment -- after assigning the value to the variable the value is incremented. i.e 3.

@ALL.
int x=3;
i=i++; which means i=i+1; => i=4;
printf("%d",i); prints 4.
int x=3;
i=i++; which means i=i+1; => i=4;
printf("%d",i); prints 4.

Here the value of i is post incremented in the same memory space of i so the value 4.

Always go with the last operation here i++ is the last operation so the answer is 4.

First i = 3 will be assigned to i (i = i++).
Then i will be incremented to 4.
Then i will be incremented to 4.

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;

I have compiled this program and I get output 3.
So, the correct answer is 3.
So, the correct answer is 3.

I just ran it on my computer and it is 3 not 4. It's a post-increment.
