Which bitwise operator is suitable for checking whether a particular bit is on o

Which bitwise operator is suitable for checking whether a particular bit is on or off?

2) Consider the following statements:

 int a=2, b=3, c=4;
 a=(b++) +c;
 b=a+(++c);

3) What is the output of this C code?

 #include <stdio.h>
     int main()
     {
         int a = 10, b = 5, c = 5;
         int d;
         d = a == (b + c);
         printf("%d", d);
     }

4) What is the output of this C code?

#include <stdio.h>
     int main()
     {
         int x = 2, y = 2;
         x /= x / y;
         printf("%d\n", x);
         return 0;
     }

					  

5) The precedence of arithmetic operators is (from highest to lowest)
