How to set n-th bit of *x to v value in C

Question

I need to implement this method.

I have the unsigned * x, I need to set v value in the n-th bit, using bitwise operators in C.

void set_bit(unsigned * x,
             unsigned n,
             unsigned v){

    //I need the code here, thanks for your help!
}

Did you read the C manual regarding bitwise operators? What have you tried so far? — lurker, Jan 27 '18 at 01:40

Here's a macro to do that

#define SETBIT(var, bit) ((var) |= (1 << (bit)))
