Answer:
Option 3 is the correct answer.
Explanation:
- In c, c++ or Java programming language, The for loop takes three parameters in which first is an initialization, second is condition check and the third is an increment. None of the other loop (except for loop) takes three parameters. The other loop takes only one parameter and that is the condition check.
- So when a user knows about the times of iteration then it is a good choice to use the for loop but when the person does not know about the times of iteration if the loop. It means the iteration of the loop is based on the condition then it is a good choice to chose while or Do-while loop.
- The above question wants to ask which loop for a user can best if he familiar with the iteration of the loop then the answer is for loop which is started from option 3. Hence Option 3 is the correct answer while the other is not because--
- Option 1 states about the do-while loop which takes condition only.
- Option 2 states about the while loop which also takes condition only.
- Option 4 states about the infinite loop which is not any loop.
- Option 5 states about none of these which is not correct because option 3 is the correct answer.
Answer:
# create the file
filename = "Testfile.txt"
# for writing, we create the output file:
outPutfile = open(filename, "w")
# Writing numbers from 1-100
for item in range(1,101):
outPutfile.write((str)(item))
outPutfile.close()
# printing the contents to verify it worked correctly
infile = open(filename, "r") #note the "r" indicates the mode
fileContents = infile.read()
infile.close()
print(fileContents)
Explanation:
- Define the working file fileName = TestFile
- Create the output file for writting outPutfile = open(filename, "w")
- Use a for loop to write numbers from 1-100 to the file outPutfile.write((str)(item))
- Close the file outPutfile.close()
- You may open the file read its content and print the contents to verify it worked correctly
Answer:- Major property of a good hash code is that objects which are equal should return the same hash code .
Explanation: Hash codes is a numeric value which is used for identify a object while a equality testing .Hash code can occupy the value of any length and then returns a fixed length value. The value of hash codes are variable.
If two objects are equal then by the method of equal(object) if the hashcode() function is called on both the objects , they produce the same value.
