Answer 1

Please notice that power of 2 and square root would cancel each other out. So this line

if (sqrt(pow(rx[j][i],2)) > p1)

is equivalent to

if ( rx[j][i] > p1 )

List of errors and warnings in the code:

1. the array `rx[]` is a linear list (one-dimensional array). However, it's been misused in two places as `rx[j][i]` which is a two-dimensional array.

2. The variable `p1` hasn't been defined.
3. The array `fi[]` also hasn't been defined.
4. The header `#include <math.h>` hasn't been included.
