Explain the output...

Question

Initially i=4
Evaluate j if j=++i*i++

Answer 1

output will be 30
In C :
●precedence of postfix x++ is more than prefix ++x
●associativity of postfix is from Left to Right & opposite for prefix
[in above problem , game is of precedence , as associativity comes in picture when multiple operators of same precedence are there in single expression]

//have a look at this image to get little idea of associativity also :

//here is the code for confirmation
#include <stdio.h>
int main() {
int i=4,j=++i*i++;
printf("%d",j);
return 0;
}

Yes, sorry for the mistake there, I learned about undefined behavior there after 1 more post where I tried to use same associativity & precedence logic but things didn't appear to work good, but forgot to edit here.
//Things not go same everywhere like they go in Java. I will take care.
