Showing examples are one excellent way to illustrate Ada advantage over C.

But I think what is needed are small coding examples, where each case 
shows clearly an advantage of Ada over C.

Coders like to see code. Seeing small actual code examples, 
side-by-side, showing clearly that the Ada way is better than the C way, 
and why that is, will let the code speak for itself.

But these examples have to be written by someone who is both an expert 
in Ada and C to be fair.

There is another thing to overcome: many of the Ada advantages starts to 
show up when one is doing programming in-the-large, and this is hard to 
sell to someone who mostly thinks at the function level (the so called 
coders here?) instead of at the system level as well.
