Question

I’m having trouble putting a 1 bit at a given position.
For example if int e is one, I have put the first bit in neset_t* ne to 1.

I’ve done this so far but does not work.

typedef unsigned short int neset_t;

    void add(neset_t* ne,int e){

    int num = (int) *ne;
    num = num | e;
    *ne = (neset_t) num;
}

thanks in advance.
sorry for my english.

Answer 1

Is e is bit position?
In this case you should use

num = num | (1 << e);

instead

num = num | e;
