Write a function that overloads the multiplication * operator to multiply a 1 x 4 matrix by 4 x 1 matrixthe function defiinition should multiply corresponding array elements and return sum.

int operator*(ARRAY & A, ARRAY & B) {

int sum = 0;

for(int k = 0; k<4; k++)

{ sum = sum + A.a[k] * B.a[k];

}

return sum; }

Write a program to test your function.
