a.
b.

Respuesta :

Answer:

For expr1 = index 5, length 5

For expr2 = index 0, length 4 and index 21, length 5

string quote = "Four score and seven years ago";

           string expr1 = quote.Substring(5, 5).ToUpper(); // "SCORE"  

           string expr2 = quote.Substring(0, 4) + quote.Substring(21, 5).ToLower(); // "fouryears"

           Console.WriteLine(expr1);

           Console.WriteLine(expr2);

Explanation:

Then code is written in c# and it produces SCORE and f

ouryears

Substring takes 2 arguments, the start of the specific character and the length
