Consider the following methods in Ruby, what will be the values of the formal parameters after the following calls are made. list = [1, 2, 3, 4, 5] def tester(p1, p2, *p3)... end tester(\'first\', *list, \'mon\' rightarrow 72, \'tue\' rightarrow 68, \'wed\' rightarrow 59); list = [1, 2, 3, 4, 5] def tester(p1, *p2, p3)... end tester(\'first\', *list, \'mon\' rightarrow 72, \'tue\' rightarrow 68, \'wed\' rightarrow 59); list = [1, 2, 3, 4, 5] def tester(*p1, p2, p3)... end tester(\'first\', list \'mon\' rightarrow 72, \'tue\' rightarrow 68, \'wed\' rightarrow 59);

Solution

Formal parameter is given in output below----->

a.

main_a.rb

list=[1,2,3,4,5]
def tester (p1,p2,*p3)
    puts \"p1 is #{p1}\"
    puts \"p2 is #{p2}\"
    puts \"p3 is #{p3}\"

end
tester(\'first\',*list,\'mon\'=>72,\'tue\'=>68,\'wed\'=>59);

Output :

b.

main_b.rb

list=[1,2,3,4,5]
def tester (p1,*p2,p3)
    puts \"p1 is #{p1}\"
    puts \"p2 is #{p2}\"
    puts \"p3 is #{p3}\"

end
tester(\'first\',*list,\'mon\'=>72,\'tue\'=>68,\'wed\'=>59);

Output :

c.

main_c.rb

list=[1,2,3,4,5]
def tester (*p1,p2,p3)
    puts \"p1 is #{p1}\"
    puts \"p2 is #{p2}\"
    puts \"p3 is #{p3}\"

end
tester(\'first\',*list,\'mon\'=>72,\'tue\'=>68,\'wed\'=>59);

Output :
