Writing a program in C++ and I need help [migrated]
- by compscinoob
So I am a new to this. I am trying to write a program with a function
double_product(vector< double a, vector< double b) that computes the scalar product of two vectors. The scalar product is
$a_{0}b_{0}+a_{1}b_{1}+...a_{n-1}b_{n-1}$.
Here is what I have. It is a mess, but I am trying!
#include<iostream>
#include<vector>
using namespace std;
class Scalar_product
{
public:
Scalar_product(vector<double> a, vector<bouble> b);
};
double scalar_product(vector<double> a, vector<double> b)
{
double product = 0;
for (int i=0; i <=a.size()-1; i++)
for (int i=0; i <=b.size()-1; i++)
product = product + (a[i])*(b[i]);
return product;
}
int main()
{
cout << product << endl;
return 0;
}
