about: map

I made a map like this:

typedef struct
{
char * Source;
bool DirFlag;
} RegInfo_t;

struct Comp
{
bool operator()( RegInfo_t k1, RegInfo_t k2) const
{
return strcmp( k1.Source, k2.Source )<0;
}
};

map< RegInfo_t, time_t, Comp > m_RegInfo;

RegInfo_t mystruct;
mystruct.Source = "Test";
mystruct.DirFla g = false;
time_t t;
time(&t);

m_RegInfo.inser t( make_pair( mystruct, t) );

My Question:

m_RegInfo[mystruct] == t ????

Please help , thanks.

How can you read a file, character by character, including whitespace?

That's not a question. It's a code fragment followed by 4 question
marks.

Mike,

Thanks for the response. I'm sorry, I wasn't very clear.

I needed to read a text file character by character, including whitespace.

Its a homework assignment to read names (one to a line) and put them in
strings.

first, middle, last.

I found my answer with on at cplusplus.com

inChar = inFile.get();

I seem to have written my class to eat between 2 and 10 characters after
each /n.

My big decision statements are

if (inChar == ',' || inChar == '/n'|| inChar == EOF) // last-first-middle
entry method

if (inChar == ' ' && flag == 0) // first-middle-last entry method

// flag is incremented when first is assigned to prevent inadvertently
entering the decision cycle again.

and

if ( strlen(first.c_ str()) > 1 &&
strlen(middle.c _str()) > 1 &&
strlen(last.c_s tr()) > 1) // verifying that each name has an assignment
before exiting.
I believe my mistake lies in this logic somewhere but I'm too close to my
problem to see it.

Thanks in advance for any help!

Only for standarize: Why don't you use:

if (first.length() >1 &&
middle.length() >1 &&
last.length()>1 )

don't you know the std::string has a length() member? :)

I have 2 questions: 1. strlen returns an unsigned (size_t) quantity. Why is an unsigned value more approprate than a signed value? Why is unsighned value less appropriate? 2.
