First line integer telling you the size the system

2. Copy in subroutine for determinate that you wrote before and modify it to be integer only to help you invert matrix.

3. Read in 2 numbers at a time, decrypt them, and insert them into a character string. character*32 will hold the entire messsage.

2. Next n lines each have n+1 real numbers representing the coefficients of the system and the right hand side value.

3. The above repeats until the ’First line’ = 0

You will write the subroutines Cramer, ColumnInsert, and the function De-terminant. You should be able to just copy in your determinant function that you did in class.

1. First, write ColumnInsert and Determinant. As you work on each one, only concentrate on what that particular subroutine does.
