A pro of HCI technology is that its user friendly and a con about it is that you have to teach the user what to do or guide them!
Answer:
The answer is "Option A".
Explanation:
The program to the given question can be given as:
program:
var1 = "Happy" #defining variable var1
var2= "Birthday" #defining variable var2
var3 = (var1+var2) *2 #defining variable var3 and calculate value
print (var3) #print value.
Output:
HappyBirthdayHappyBirthday
In the above python program, three variable is defined, that is var1, var2, and var3, in which variable var1 and var2 we assign a value, that is "Happy" and "Birthday".
In variable var3 we add the value of var1 and var2 variable and multiply by 2. It will print the variable value two times. and other options are not correct that can be defined as:
- In option B and C, Both variable var1 and var2 print there values two times but in option B var1 value print two time and var2 value print one time only and option C var1 variable value is print only one time and var2 variable value is print two times that's why it is not correct.
- In option C, Both variable var1 and var2 print there values two times that's why it is not correct.
Answer:
Option B and C are the correct answer for the above question
Explanation:
The above question asked about the work of the programmer to catch an error of the program--
- Then the option B states that the programmer needs to prints the value of the various program variable on every line of the program which is the correct solution because it is used to find the error easily. It defines the value of every variable in every place of the program and the programmer caught the error statement in the program if anywhere the variable gets the false value.
- The C option states to help from a friend, it is also a good solution because the friend can easily be caught the error of the program by seeing every line of code.
- But the other option is not correct because the option A states that the change the name of the variable which is not a result of anything.
- And the option D states that the code will be retyped again which is also not justify anything.
