printf("%d %d",i,j);
}
#include<stdio.h>
void main()
{
int i=10,j=20;
j=i,j?(i,j)?i:j:j;
printf("%d %d",i,j);
}A10 10

int c=10000;
Show Explanation
- notice the comma operator when variables are separated by them they are evaluated from left to right and only last value is considered ( it has less precedence than assignment operator)
so due to the precedence of assignment being high the assignment is done first and then comma operator is evaluated be the expression finally evaluates to j=i,(j?(i,j)?i:j:j); - so the value of i is assigned to j
you can run the same program with one more variable C the value of j will be equal to the value of C as per above logic
#include
void main()
{
int i=10,j=20;
int c=10000;
j=c,j?(i,j)?i:j:j;
printf("%d %d",i,j);
}
