4 the Cable Modem
Explanation:
Answer:
Average is the following the default option of auto sum feature
Answer:
return 8 * x
Explanation:
Given
The attached code segment
Required
Which single statement can replace the program body
From calculate(), we have:
The first line (x = x + x) implies that:
So, on the next line; 2x will be substituted for x
i.e.
becomes
So, on the third line; 4x will be substituted for x
i.e.
becomes
In programming: 8x = 8 * x:
This means that: return 8 * x can be used to replace the body

Answer:
Option (B) and (C) is the correct option to the following question.
Explanation:
Because the function is the module of the program and we call that function again and again anywhere whenever we need that function in the program.
Function is used to carry out any operation which is used in the program many times and it creates the program short and simple.
<u>For example</u>: if we need to add or multiply two numbers many times in the program then, we create one or two functions for addition and subtraction or one program for both, when we need them we call them.
