Apply - Arguments

Now that you've had a chance to see how arguments can be used in a command line to pass information, let's see how much of it has made sense to you.

Following are a few questions about what we covered in the Connect section; click on what you think is the right answer. This page has been set up to let you know immediately if you've got it right.

Question 1 - Arguments

Consider the following command line:

>TempConvert 98.9 Celsius

What would argc be?

Celsius

Question 2 - Arguments

In the following code declaration

int *ip;

What is ip?

An Integer, or int

A pointer to int

A double pointer to int

A pointer to char

Question 3 - Arguments

In the following code declaration

char **cpp;

What is cpp?

A character, or char

A pointer to a char

A double pointer to int

A pointer to a pointer to char

Question 4 - Arguments

What is the purpose of a double pointer to a char?

It is simply a tool for memory declaration.

It allows for an array of characters, which allow words, or strings to be stored and used.

It provides a way of allocating space for an array of pointers to char; each of those pointers can then point to a string

There is no such concept as a double pointer to char in C.

Finally, we’ll think about benefits and limitations of this method of data-passing (Reflect), and think about other ways of providing information to programs (Extend).
