Answer:
is this a question or not?
Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.
Answer:
False
Explanation:
The functions that was made for display content can get arguments of different type e.g. (Int, string, Array, Objects) and if you want to display n values you only have to check the syntax of your programming language to separate one of each other
# Python example
a = "Hello-"
b = "World"
c = 10
print(a,b,c)
#Out: Hello-World10
I hope it's help you.
Answer:
The code is not dereferencing the pointers. You have to place an asterisk in front of the pointer to read the value the pointer points to.
Explanation:
So "if (str1 != str2)" must be "if (*str1 != *str2)".
likewise:
while (*str1 != 0 && *str2 != 0)
and
result = (*str1 == *str2);
Answer:
names = ['Peter', 'Bruce', 'Steve', 'Tony', 'Natasha', 'Clint', 'Wanda', 'Hope', 'Danny', 'Carol']
numbers = [100, 50, 10, 1, 2, 7, 11, 17, 53, -8, -4, -9, -72, -64, -80]
for index, element in enumerate(names):
if index % 2 == 0:
print(element)
for num in numbers:
if num >= 0:
print(num, end = " ")
count = 0
for i in numbers:
count += i
avg = count/len(numbers)
print("sum = ", count)
print("average = ", avg)
for num in numbers:
if num % 2 != 0:
print(num, end = " ")
Explanation:
I'm stuck on the last two.. I have to do those too for an assignment.
