Parsing .xls and .csv files
As shot in the dark, but can I do something like this? and is it efficient? public boolean isQuote = false; public int sizeOfFile = GetsizeOfFile( ) ; // hold the file chars in some array and loop thru it for(int i=0; i<FileArray[sizeOfFile]; i++) { if( FileArray[i] == ' "... -

String concat using overloaded operators.
oh no I can't do that because 'this' refers to the String object left of the operator doesn't it? I'm sorry, I'm not in front of a compiler right now thats why I posted the above before giving it a try first. I've been thinking about it all day and this forum is the only thing I can access to...- 0x4B47

String concat using overloaded operators.
Is it ok for me to do this: String operator+( const String & other) { length = this->length + other.length; const char* s = this->(pStr-1) + other.pStr; setString(s); return *this; } KG 01001011 01000111- 0x4B47

What does "LPCTSTR" do
/Per, I didn't know that! Thanks for that info. But I was just wondering, the syntax suggests that it IS a type-cast. Isn't that line of code essentially just type-casting the pointer? What I mean to ask is, won't the compiler just make whatever is returned by GetFileName() a 64-bit (QWORD)...- 0x4B47

LPCTSTR = Long Pointer to a ConsTant STRing. So you're basically type-casting whatever is returned by GetFileName() to LPCTSTR. /Per explanation is a better one. I thought I'd just add my two pennies :)- 0x4B47

char* arr = “Nisse”; ?
If you like at the end of your program you can do: arr = 0; Thats a way of making sure the pointer is 'NULL'ed and put in a nice consistant state before exiting your program. keyword 'delete' only needs to be used if you use the keyword 'new'.- 0x4B47

String concat using overloaded operators.
Hi fellow coders, Consider the class, class String { public: String( const char* = "" ); String( const String & ); ~String(); const String& operator=( const String & ); const String& operator+( const String & ); private: int length; char* pStr; void setString( const char* ); //...- 0x4B47

Dynamic object creation and dangling pointers.
Hi fellow coders, I have a problem that I need assistance with. Consider this class in intset.h: class CIntSet { public: CIntSet(); ~CIntSet(); CIntSet* intersect( CIntSet* is1, CIntSet* is2 ); CIntSet* unionofSets( CIntSet* is1, CIntSet* is2 ); private: int* intSet; }...- 0x4B47

Complex Numbers
chippermdw, i know its modelling, but you didnt understand my question and just jumped into a frenzy of 'representation'. The reason why I asked what i did was from a 'performing a calculation' perspective, which Salem understood and answered for me quite simply and nicely. I wasnt sure whether... -
Complex Numbers
Fellow coders, We know that a complex number is a number that is represented as so: ComplexNumber = realPart + imaginaryPart * squareroot of -1 How can we represent this number in a computer program? Because the squareroot of -1 is an error. Kunal.
