string a = "My name is Fred. Is your name Fred?";
string b = "I like fish and fries. Farewell.";
int countF = 0;
Write a few lines of code (need not be a separate function) to:
(a) Concatenate strings a and b separated by space into a string f. Print it.
(b) Allot countF number of times that uppercase F appears in string f. Print value of countF.
(c) Print "Fred's found" if string f contains letters Fred.
