Answer the following statements true (T) or false (F)

1. If A is an array of integer elements, then the statement A = A + 1; adds 1 to each element of A. 2. If A is an array of integer elements, then the statement A[3] = A[3] + 1; adds 1 to the third element of array A. 3. Most array subscripts are of type float. 4. If A and B are arrays of the same data type, then the statement A = B; copies each element of B to the corresponding element of A. 5. If b is an array of integer elements, then the statement b[3] *= 2; doubles the value of b[3].
