Answer:
Latex replaced wax because it did the same thing and was used for the same things that wax would be used for

Answer:
Yes. Pseudocode is an improvement over the IPO chart because it lays out the sequence of steps for a particular program
Explanation:
The input–process–output (IPO) chart is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. The chart has three components (Input, Process and Output), and you write the description of each component in plain English, not code or mathematical formulas.
Pseudocode is a procedure for solving a problem in terms of the actions to be executed and the order in which those actions are to be executed.
Pseudocode is an improvement over the IPO chart because it shows the step by step sequence to be followed by a particular program unlike the IPO chart which just break the program into Input, Process and Output.

Explanation:
a. int foo+; (foo+ is an invalid identifier because + is not a valid char in identifiers)
b. foo int; (Syntax error is any error where the syntax is invalid - either due to misplacement of words, bad spelling, missing semicolons etc.)
c. Static semantic error are logical errors. for e.g passing float as index of an array - arr[1.5] should be a SSE.
d. I think exceptions like NullReferenceException might be an example of DME. Not completely sure but in covariant returns that raise an exception at compile time (in some languages) might also come in this category. Also, passing the wrong type of object in another object (like passing a Cat in a Person object at runtime might qualify for DME.) Simplest example would be trying to access an index that is out of bounds of the array.
One million is the answer.
