I need to convert a string IP to an unsigned int (uint32), but however solutions I've found elsewhere have not worked (such as `atoi`).
When using `(uint32)"54.171.82.217 ";` : [URL] ....

How can I correctly convert the string version of the IP to the uint32 type?

View 9 Replies View RelatedI have a bitmap header information in the struct
typedef struct tagBITMAPINFO {
BITMAPINFOHEADER bmiHeader;
RGBQUAD bmiColors[1];
} BITMAPINFO
The total size of this is 1080.
Now i want to convert this into a unsigned char pointer.
unsigned char * pBMPHeaderData;
I already got the raw image data in another unsigned char buffer.
unsigned char* pRawBMPData;
Now i want to make a complete BMP image by adding the header info and raw data into a new unsigned char pointer. For this i need to convert the BITMAPINFO struct into a unsigned char *
So the new buffer will be,
unsigned char * pCompleteBMPIMageData = pBMPHeaderData + pRawBMPData;
how to do this?
How can i write a function that will read an "unsigned integer" into a variable of type "unsigned short int"? i can not use cin >> inside the function.. so i am looking for atleast a hint!

What is the safe way to cast or convert here?
I have the following code, but it crashes on the "data = " line...

I need to convert the bit representation of an unsigned char into a string.

heres the function:
string ToString ( const char * format, ... )

string f;
f=ToString("hello world");
gives me several errors:
"error: crosses initialization of 'std::string f'"
"error: jump to case label [-fpermissive]"

My teacher has done a very poor job of teaching us anything this year. When he taught us for loops, he wrote one on the board, didn't explain any of it, then said now that you know for loops we can implement them in a code. but anyway, we need to write a code for converting a string to an int and all the examples i find on the internet use pointers but we aren't allowed to use those yet.
