Program Plan Intro

The variables:

The variable is a named location in a memory. In this location the program can manipulate the data.

This location holds the value of the variable.

The value of the variable gets changed in the program.

The C++ variable can be any type like “int”, “float”, “char” and so on.

Expert Solution & Answer

Explanation of Solution

Rules for naming the C++ variable:

The name of the variable must begin with a letter or underscore.
The name of the variables is case sensitive.
The name of the variable can be constructed with digits and letters.
Special symbols other than underscore are not allowed in the variable name.
Valid variable names are, “i_think_i_am_valid”, “i_may_have_2_many_digits_2_be_valid”, “_I_start_and_end_with_underscores_”, “I_AM_LONG_AND_HAVE_NO_LOWER_CASE LETTERS”
Example for invalid variable name is “I_Have_A_Dollar_$ign”. This is invalid because the name contains the special character “$”.

From the given set of variable names, the invalid variable name is “I_Have_A_Dollar_$ign”. Hence the correct option is “d”.

What does the value of the top variable indicate in this ArrayStack implementation? What will happen if we call pop on this stack? What value will be returned, and what changes will occur in the array and the top variable? 3. If we push the value "echo" onto the stack, where will it be stored in the array, and what will be the new value of top? 4. Explain why index 0 contains the string "alpha" even though top is currently 3. 5. What would the state of the stack look like (values in the array and value of top) after two consecutive pop 0 operations?

Please solve and show all work. Suppose there are four routers between a source and a destination hosts. Ignoring fragmentation, an IP datagram sent from source to destination will travel over how many interfaces? How many forwarding tables will be indexed to move the datagram from the source to the destination?

Please solve and show all work. When a large datagram is fragmented into multiple smaller datagrams, where are these smaller datagrams reassembled into a single large datagram?
