What will be the value? [topic: logical and bitwise or operator]

int a = 1, b = 2;
int c = a | b; 
int d = a || b;

Ans: value of c will be 3 and d will be 1

c  = (binary 01) OR (binary 10)
   = (binary 11)
   = 3
   
d   = 1 (Logical OR) 2 
    = (1 is not FALSE) Logical OR (2 is not FALSE) 
    = (TRUE) Logical OR (TRUE) 
    = TRUE 
    = 1
