What will be the output of the following program?
int main() {
union {
int i;
int j;
void f() {
printf("i=%d, j=%d\n", i, j);
}
};
i = 3;
j = i+++ ++i;
f();
return 0;
}
ERROR
i+++ at line 20 is not executable.
pardon me if I am wrong.
i = 5, j = 8
This statement,: j = i+++ ++, i is actually
j = i++ + ++i;
i = 3 at first, then starting from left we look at i++, so the expression takes the values as 3 because i++ is a post-increment and afterwards increments i to 4. Then it looks at the other part of the expression which is ++i so for this it does a pre-increment and i becomes 5 and then 3 + 5 is added together and assigned to j.
