How to do a square root:

Step 1 (applies to all programming languages)
    Look up square root in the manual.

Step 2 (applies to all programming languages)
    Do what the Fine Manual says.

In Ada, use the index, which points you to A.5.1, and do

	with Ada.Numeric_Elementary_Functions;
	use  Ada.Numeric_Elementary_Functions;

	...
	    sqrt(X)
	...

Section G.2.4 even gives you error bounds on the result, which no other
language standard I've checked does.  Just because of that, I'd rather
do a square root in Ada than anything else.

Simple I/O:

Step 1
    Look it up in the manual
Step 2
    Do what the Fine Manual says.

*SIMPLE* I/O involves withing and using a couple of standard packages,
and then using Put, New_Line, Get, and Skip_Line.  Pretty darned simple.
It has not been a problem for first-year students at this university.

Ada does not support Fortran-style formatted I/O, nor PL/I style
formatted or pictured I/O (but see Interfaces.COBOL).
