C << operator

/*
 * The << operator shifts the bits of an integer a certan amount of steps to the left
 * So a << n means shifting the bits of a to the left n times
*/
#include <stdio.h>

int main() {
   int a = 10;  // 00001010 in binary
   int n = 2;

   printf("Result : %d\n", a << n);
   // Result is 40 which is OO101000 in binary

   return 0;
}

// This also means that a << n is an equivalent to a * 2^n

C |= operator

// | is the binary "or" operator
// a |= b is equivalent to a = a|b

#include <stdio.h>

int main() {
   int a = 10;  // 00001010 in binary
   int b = 6;   // 00000110 in binary

   printf("Result : %d\n", a |= b);
   // Result is 14 which is OOOO111O in binary

   return 0;
}
