Answer:
ValueError
Explanation:
Required
Determine the error the program returned
The above will return a ValueError error and the reason is as follows.
The first line of the program initializes variable as 'live'.
The next line tries to convert answer to integer and this is where it returns the error'.
On the second line, variable amount expects that the answer variable to contain number e.g. '567' but because it doesn't contain a complete number (i.e. unexpected values), the program returns a ValueError.
Answer:
Yes, overloading is one of the methods which are popular in programming language. Overloading basically refers to the same function but different signature called function overloading or method overloading. It is the ability to define the multiples method by using the single identifier.
The overloading is important because it has the ability to design the multiple method by using similar name. It also provide the high flexibility to the programmers to call the same method in the data. overloading basically provide the high clarity in the code.
Overloading is used to achieved the compile time polymorphism.
Following are program of function overloading in c++ are:
Class abc // creating class
{
public:
int p;
void fun() // function fun with no parameter/
{
cout<<” hello “;
}
void fun(int a) // function fun with parameter
{
p=a;
cout<<p;
}
};
int main() // main function
{
abc ob; // creating object
ob.fun();// print hello;
ob.fun(6);// print 6
return 0;
}
Explanation:
In this program the function fun() have same name but different signature in the main method we create the object of class abc i.e ob. ob.fun() this statement called the function with no parameter and ob.fun(6) this statement will called the function with integer parameter.
Answer:
b. mkdir -p ~/2019projects/project/projectplans
Explanation:
mkdir command in Linux environment is used to create a new directory. This command is used to create a folder to store the information in organized manners.
-p is used to create a parent folder in the directory. If we want to start a new project or want to store information about some new topic we will create a new folder for that purpose. So, -p is used to create a new folder in directory.
In above mentioned case, this is the first project that Mindy started in 2019, so she should create a parent directory of 2019 to save all projects details that she worked in 2019. So she should use -p with mkdir command to make 2019 as a parent folder.
There is always a risk of you losing files and then you may have to pay for it depending on what services you use.
