Homework 2 notes.

Notes

• I intend you to fix this and resubmit, because I love grading soo much.
  • but progname < input.txt | diff - output.txt must produce NOTHING
  • And you should fix ALL items noted in the feedback.
• In the future, if your program does not compile, I will not allow a redo.
• In general, provide the most simple solution to the problem.
  • Adding complexity is bad.
  • Feature creap is bad.
• Homework is time to follow the specification,
  • Do what was asked
  • Do exactly what was asked
  • Do no more that what was asked.
  • Be creative on your programs AFTER they are graded.
• Follow formatting instructions
• Watch your identifiers:
  • variables: variableName
  • functions: FunctionName
  • constants: CONSTANT_NAME
• No gotos
  • No continue or goto or exit
  • break only in switch/case statement
  • return only as the last statement in a function
• Never do

  • if (condition) statement; 

  • Always do

  • if (condition) {
        statement;
    } 

• For the comma problem, Consider:

  • i = first;
    cout << i
    for(i += skip; i &ls; end; i += skip) {
        cout << ", " << i;
    } 

• In general try to avoid

  • if (condition) {
    } 
    if (not condition) {
    } 

  • Prefer

  • if(condition) {
    } else {
    } 

• Don't pass parameters unless they are needed
  • If a argument is not used in the calling function or passed to any other function, the parameter should be a local variable.
  • IE GetData(start, stop, skip, file, junk);
  • Do not return a value if it is never used.
• Do not use most components of the standard library
  • vectors, maps, lists, queues, ...: we will discuss these.
  • stringstreams: you should learn to master input
  • You may, at this point use ifstream, ofstream, string.
  • In general, if we have not discussed it in class, you may not use it.

Possible point loss:

• General:
  • Your program does not compile: No Credit.
  • Your program does not work on the default data: -10
  • You hardcoded the solution into your code, no credit.
  • You should not be using stringstream, you can do this with basic input, which you should be mastering at this point. -3
• Specified I/O
  • You didn't include your name and identifying information. -1
  • There should be no newline after the file prompt before the response: -1
  • Your error message text is incorrect. -1
  • Your file prompt is incorrect. -1
  • You are missing a newline after the file prompt response, See 1,b ("read in the user response and print a newline.) -1
  • The error message should start with a tab. -1
  • You do not print the correct newline proceeding each problem output. -1
  • The output should be #, # -1
  • You produce extra, not requested output. -1
  • You have extra newlines at the end of your program. -1
  • You have an extra space at the end of each counting line. -1
  • Your program exits after an incorrect file name, this is not right. -1
  • You did not print each problem description. -1
• Failure to follow style
  • variable names should be formatted in camel case starting with a lower case letter. IE: variableName -1
  • Function names should be formatted in camel case starting with a upper case letter IE: FunctionName -1
  • Identifiers should indicate their use, you have some that don't. -1
  • Please use function prototypes, place the functions below the main routine. -1
• Poor programming practices
  • No continue, exit, or goto statements, only return at the end of a function, only break in a switch/case statement -5
  • Only pass parameters that are needed. If it is not used in the calling routine, or passed to another routine, it should be a local variable. -1
  • You have an end of file loop bug. -3
