How to search elements in vector

[krishnakumartm]

Hi, I have a structure, i am keeping the structure in vector to store multiple elements, my structure looks like struct mystruct { id = 1; pid= 2; } i used vector to store like vector vectStruct; like this i have 100 elements, i need to find the elements whose pid = 2 How can i search structures in vector, how to iterate through result. Thanks in advance

Use a functor for that:

struct find_pid
{
find_pid ( int pid ) : m_pid_to_find(pid) { }
bool operator() ( const mystruct& s ) const { return m_pid_to_find == s.pid; }
protected:
int m_pid_to_find;
};

vector<mystruct>::iterator i = std::find_if ( vectStruct.begin(), vectStruct.end(), find_pid(2) );

Hi, Thanks for your replay, i tried what you explained in ur replay but when i pass integer to find_pid(4) but it is giving error like cannot convert from int to mystruct& ---------------------------- KRISHNA KUMAR T M
