How to erase value from vector of struct using erase-remove idiom?

Question

How to erase all values from vector of struct, where struct value k equals to 0?

struct tabuRecord {
int x;
int y;
int k;
tabuRecord( int x, int y, int k)
    : x(x), y(y), k(k){}
};  

vector <tabuRecord> tabu;

v.insert(v.begin(), tabuRecord(1, 2, 3));
v.insert(v.begin(), tabuRecord(4, 5, 0));
v.insert(v.begin(), tabuRecord(7, 8, 9));
v.insert(v.begin(), tabuRecord(10, 11, 0));

I have tried to

tabu.erase(std::remove(tabu.begin(), tabu.end(), tabu.k=0), tabu.end());

and

tabu.erase(std::remove(tabu.begin(), tabu.end(), tabuRecord.k=0), tabu.end());

I guess what you want to do is to remove all objects that have k==0, so create a lambda for that:

tabu.erase(
    std::remove_if(tabu.begin(), tabu.end(),[](const tabuRecord& t){return t.k == 0;}),
    tabu.end());

std::remove cannot work because it's not one value that you want to remove, but all values with a specific pattern, which is what std::remove_if does.
