Q: 关于STL Vector作为函数参数使用问题

#include <cstdlib>

#include <vector>

#include <iostream>



using std::vector;

using std::cout;

using std::endl;

using std::ios;



void calculateAdjClosePrice(double *close, double *open, double *adj_close);



int main(int argc, char** argv) {

    vector<double> close;

    vector<double> open;

    vector<double> adjclose;

    close.push_back(2.02);

    open.push_back(1.52);

    adjclose.push_back(1);

        

    calculateAdjClosePrice(close,open,adjclose);

    

    return 0;

}



void calculateAdjClosePrice(vector<double> close, vector<double> open, vector<double> adj_close){

    int size=close.size();

    adj_close.clear();

    for(int i=0;i<size;i++){

        if (close.at(i)>open.at(i))

            adj_close.push_back(close.at(i)+0.01*open.at(i));

        else

            adj_close.push_back(close.at(i)-0.01*open.at(i));        

    }

    vector<double>::iterator p;

    for (p=adj_close.begin();p!=adj_close.end();p++)

        cout<<*p<<endl;

}
