Which of the following is the java comparison operator for "not equal to"

1 answer:

8 0

You need to provide "the following", otherwise other users cannot answer your question.

However, the Java operator for "not equal to" is "!=".

// For example.
if (1 != 2) {
System.out.println("1 doesn't equal 2");
}

The if-statement in the code above will always run, since 1 is not equal to 2.

Define a function begins_with_line that consumes a string and returns a boolean indicating whether the string begins with a dash

Ksju [112]

Answer:

The program written in python is as follows:

def begins_with_line(userinut):

while userinut[0] == '-' or userinut[0] == '_':

print(bool(True))

break;

else:

print(bool(not True))

userinput = input("Enter a string: ")

begins_with_line(userinput)

Explanation:

The program makes use of no comments; However, the line by line explanation is as follows

This line defines the function begins_with_line with parameter userinut

def begins_with_line(userinut):

The following italicized lines checks if the first character of user input is dash (-) or underscore ( _)

while userinut[0] == '-' or userinut[0] == '_':

print(bool(True)) ->The function returns True

break;

However, the following italicized lines is executed if the first character of user input is neither dash (-) nor underscore ( _)

else:

print(bool(not True)) -> This returns false

The main starts here

The first line prompts user for input

userinput = input("Enter a string: ")

The next line calls the defined function

begins_with_line(userinput)

NB: The program does not make use of if statement
