Answer the given question with a proper explanation and step-by-step solution.

 ANSWER IN C++ 

18. Implement the following method that creates and returns a new array.
/**
* Return a new array containing the pairwise maximum value of
* the arguments. For each subscript i, the return value at [i]
*will be the larger of x[i] and y[i].
*
* @param x an array of double values
* @param y an array of double values
* @return pairwise max of x and y
*/
double* pairwiseMax (double x[], double y[]){
}
19. Implement the following method that reads through two integer arrays.
/**
* Computes the final average grade for a student. The labs are
* worth 40% and the exams are worth 60%. All scores range from
* 0 to 100, inclusive.
*
* @param labs the student's lab scores
* @param exams the student's exam scores
* @return weighted average of all scores
double finalGrade(int labs[], int exams []) {
