Answer: 443
Explanation:
Port 443 will need to be enabled for secure transactions to go through because it is the default port for HTTPS which is the transfer protocol for secure communication.
This way your credit card transactions will be encrypted to ensure protection from those who would seek to steal your data and your money.
Program p1;
var a,b,c,d : integer; {i presume you give integer numbers for the values of a, b, c }
x1, x2 : real;
begin
write('a='); readln(a);
write('b='); readln(b);
write('c=');readln(c);
d:=b*b - 4*a*c
if a=0 then x1=x2= - c/b
else
if d>0 then begin
x1:=(-b+sqrt(d)) / (2*a);
x2:=(-b - sqrt(d))/(2*a);
end;
else if d=0 then x1=x2= - b /(2*a)
else write ("no specific solution because d<0");
writeln('x1=', x1);
writeln('x2=',x2);
readln;
end.
Answer:
Answer to the following question are,
Explanation:
Because these are the two associations data structures.
- Association List: are referred to that data type which contains the pair of the key and item in the Java Programming Language and Python Programming Language, it is called a dictionary data type.

Answer:
It can only be used in superclasses
Explanation:
In computer language, a reserved word is a word that cannot be used as an identifier, such as the name of a variable, function, or label, it is "reserved from use".
If your method overrides one of its superclass's methods, you can invoke the overridden method through the use of the keyword super, it can also be used to refer to a hidden field.
We can conclude that the correct answer is "It can only be used in superclasses" because, in a subclass’ constructor, we can call the superclass’ constructor with the keyword super instead of the superclass’ (constructor’s) name.
