Answer:
The solution code is written in Python 3 as below:
- outfile = open("greeting.txt", "w")
- outfile.write("Hello World")
- outfile.close()
Explanation:
To create a simple text file in Python, we can use Python built-in function, <em>open()</em>. There are two parameters needed for the open() function,
- the file name and
- a single keyword "w". "w" denote "write". This keyword will tell our program to create a file if the file doesn't exist.
The statement <em>open("greeting.txt", "w")</em> will create a text file named "<em>greeting.txt</em>" (Line 1)
To fill up the content in the greeting.txt, we use <em>write()</em> method. Just include the content string as the argument of the <em>write()</em> method. (Line 2)
At last, we use <em>close() </em>method to close the opened file,<em> outfile</em>. This will release the system resource from the<em> outfile.</em>
Answer:
I don't know if this is right output is {1,3}
Explanation:
Answer: b. 11
Explanation:
//The initial value is 1
//let call the value as x
x = 1
//then the user updated the value to 10
//so now x is 10
x = 10
// and update the workflow to 11
//so now the value of x is 11
x = 11
even if the programmer print x, so the output will be 11
Answer:
The following code are:
public void dissolve() {
setRed(getRed()+1);
setGreen(getGreen()+1);
setBlue(getBlue()+1);
alpha+=1;
}
Explanation:
Here, we define the void type function "dissolve()" inside it, we set three function i.e, "setRed()", "setGreen()", "setBlue()" and then we increment the variable "alpha" by 1.
Inside those three mutators method we set three accessor methods i.e, "getRed()", "getGreen()" , "getBlue()" and increment these accessor by 1.
The values will not be returned by the mutator functions, the accessor will be returned the values.
