Answer:
b. an unsigned integer? (convert it to decimal)
Explanation:
Computer systems represent data and instructions in bits to be stored and processed by the processor. The buses in the computer system transfer data and instructions to various locations. Some buses can be 32 or 64 bits wide, transporting data like the 32-bit number above which covert to an unsigned integer of 2,903,506,944.
Answer:
The answer to this question can be given as:
Program:
#define class.
class PersonInfo:
def __init__(self): #constructor
self.num_kids = 0
def inc_num_kids(self): #define function inc_num_kids()
self.num_kids = self.num_kids + 1
return self.num_kids #return value.
p= PersonInfo() # creating object
print('Kids:', p.num_kids) #print value
p.inc_num_kids() #call function
print('New baby, kids now:', p.num_kids) #print value
Output:
Kids: 0
New baby, kids now: 1
Explanation:
The description of the above python program as follows:
- In this program firstly we define the class that is PersonInfo. In this class we define the constructor that is def __init__() and one function that is def inc_num_kids().
- The constructor is called automatically when the class object is created. In this constructor, we use the self as a parameter that is used to access variables that belong to class.
- In the constructor, we define the variable that is "num_kids". We assign value to a variable that is "0" and use the self for holding reference to the variable.
- Then we define the function. In this function, we increment the value of the variable by 1 and return its value.
- Then we create a class object that is p and call the function and print its value.
