Answer:
PLCs (Programmable logic controller) were original designed as replacement for relay control panels. Relay is another word for a switch. Relay control panels were made for the control of electronic instrumentents or devices. Later on PLCs were made to replace these timers and relay control panels. PLCs are more reliable, flexible and can work better in the harsh environmental situations then the relay control panels.
Answer:
A. 243
B. True
C. 0
Explanation:
Macro instruction is a line of coding used in computer programming. The line coding results in one or more coding in computer program and sets variable for using other statements. Macros allows to reuse code. Macro has two parts beginning and end. After the execution of statement of quiz4 x, 4 the macro x will contain 243. When the macro is invoked the statement will result in an error. When the macro codes are executed the edx will contain 0. Edx serve as a macro assembler.
Answer:
- import random
-
- states = {
- "Alabama": "Montgomery",
- "California": "Sacramento",
- "Florida": "Tallahassee",
- "Hawaii": "Honolulu",
- "Indiana": "Indianapolis",
- "Michigan": "Lansing",
- "New York": "Albany",
- "Texas" : "Austin",
- "Utah" : "Salt Lake City",
- "Wisconsin": "Madison"
- }
-
- correct = 0
- wrong = 0
- round = 1
- while(round <= 5):
- current_state = random.choice(list(states))
- answer = input("What is the capital of " + current_state + ": ")
-
- if(answer == states[current_state]):
- correct += 1
- else:
- wrong += 1
-
- round += 1
-
- print("Correct answer: " + str(correct))
- print("Wrong answer: " + str(wrong))
Explanation:
The solution code is written in Python 3.
Line 3 -14
Create a dictionary of US States with capital as each of their corresponding value. Please note only ten sample states are chosen here.
Line 16 - 18
Create variables to track the number of correct and inaccurate response and also round counter.
Line 19 - 28
Set the while condition to enable user to play the quiz for five questions and use random.choice to randomly pick a state from the dictionary and prompt user to input the capital of selected stated.
If the answer matched with the capital value of the selected state, increment the correct counter by one. Otherwise the wrong counter will be incremented by one. Increment the round counter by one before proceed to next round.
Line 30 - 31
Print the number of correct responses and wrong responses.
Answer:
The program to this question can be given as:
Program:
def swap_values(user_val1, user_val2): #define function
return (user_val2, user_val1) #return values
if __name__ == '__main__': #define constructor.
n1 = int(input('Enter first number :')) #input value form user
n2 = int(input('Enter second number :')) #input value form user
(n1,n2) = swap_values(n1,n2) #hold function values.
print(n1) #print values
print(n2) #print values
Output:
Enter first number :3
Enter second number :8
8
3
Explanation:
The explanation of the above python program can be given as:
- In the python program we define a function that is "swap_values". This function takes two integer values that is "user_val1 and user_val2" as a parameters and returns variable values that is "user_val2 and user_val1".
- Then we use a constructor in this we define two variable that is "n1 and n2" these variable are use to take user-input from the user and pass the value into the function.
- To hold the value of the function we use n1 and n2 variable and print these variable value.
Answer:
The correct answer to the following question will be CAD.
Explanation:
CAD - It stands for Computer-aided Design. CAD is a software used for creating some 3D designs, creative drawing or some technical illustrations and is basically used by the engineers and artists.
Many projects based on electronic can be designed with the help of this software, electronic parts like circuit boards, etc.
Various types of CAD are as follows :
- 2D (Two dimensional)
- 3D (Three dimensional)
- 3D wire frame
- Solid modeling
This enables efficiency in design's quality, also increase in engineer and artist's productivity. So, many of the computer programs should recommend the Computer-aided design software to there project partners for some 3D and effective look on their project.
