What if the output of the program below?

Question

#include <stdio.h>
int main()
{
int a = 1, b = -1, c= 0, d;
d=++a && +b || c--;
if (d)
printf("Kolkata \n");
else if(c)
printf("Delhi \n");

else

printf("Bangalore \n");
return 0;
}

Answer 1

d= (++a && +b) || c--
=( 2 && -1) || 0
= (1) || 0
= 1 || 0
d= 1
So Kolkata.

If it is
d= (++a && ++b) || c-- //c=c-1=-1
=( 2 && 0) || 0
= 0 || 0
= 0
And
c=-1
So Delhi.

IN C, other than zero is considered as true.
Operators are evaluated from left to right if there is equal priority.

Answer 2

Edit your description accurately if any missing..
= before line int a... Typing mistake?

Answer 3

No this was only the question so i was confused 🤔 i m getting d=0 but i dont know what to do with it whether the output isdelhi as it is given c=0

Answer 4

So u r saying that delhi is the output?

Answer 5

If it there just +b, then Kolkata.
If it is ++b, then d=0, but c=-1 so output is Delhi..

Answer 6

Yes. Just typo mistake. In 2nd case also I copy pasted from 1st one, and edited only so not seen that. Thanks for correction.

I think this question is from challenge section question. Question asking about explanation of output what & why..
