Q7. Set a bit, make function pointers, etc

Ans.

Setting a bit and using function pointers in software development.

  • To set a bit, use bitwise OR operator: num |= 1 << bitPosition

  • To create function pointers, declare a pointer variable and assign the address of the function to it

  • Example: int num = 0; num |= 1 << 2; // Sets the 3rd bit

  • Example: void (*funcPtr)() = &someFunction; // Function pointer to 'someFunction'
