C :: How To Read In A Character Followed By Integer Without Space
Feb 13, 2014how to carry out the conversions. The assignment is the normal hex to octal and Quart (base 4) via bit munipulation which I have worked out myself. However, I have been trying all day to figure out how to read in a string such as H1234, or O4567. How to parse the input I can handle the remainder myself. I'm just stuck and I've tried for hours.

C++ :: Reserve Space For Array?
Oct 12, 2013In my code I have a template class.
In the contructor, I create a new array arrray.
A pointer to this array is saved as an attribute.
The purpose of this attribute is that I should be able to call the array from within another function be typing *p or *(p+1) etc.
The only thing I forgot is that the array doesn't exist anymore when the constructor is done, right?
This means the space is no longer reserved for this array and the space is used for other things.
Is there a way to keep the array space reserved (even when the array does not exist anymore at the end of the function)?
C++ :: How To Capitalize Letter After A Space In Array
Jul 25, 2013The assignment is to read a data file with a list of names, capitalize the first character of the first and last name by making an array and subtracting 32 from the character, and then outputting the names onto the screen. So far I have:

using namespace std;
int main () {
string line;

Apr 7, 2013I want to do this but do not know exactly how to do it:
Create an array of space ship objects and write a program that continually updates their positions until they all go off the screen. Assume that the size of the screen is 1024 pixels by 768 pixels.

C :: Store Character Array In Reverse Order Then Display Reversed Array
Jun 14, 2013The program should store a character array in reverse order then display the reversed array.

C++ :: Character Array To Wide String?
Nov 19, 2013I am still working on my project which will be reading some old data from some old DOS files. The data stored there is naturally, char*. Once I read in my character array, how do I assign this to a wstring since my application is UNICODE?
Here is my current solution:
wchar_t* Class::Function(char *pName) {
//I verify the pointer and such first, then do the below
this->_Name.assign(pName, (pName + strlen(pName));
return this->_Name.c_str();
}
Am I on the right track here?
C++ :: Function That Subtract Value From Each Character In Array
Mar 17, 2013I have to write a function Subtracts val from each character in the array
// If the array is: abcdefghi and value = 5, then result is: 5 ascii characters subtracted from the given array
// note: Make sure the character remains in the ' '
// to '~' (inclusive)
// If character < ' ', then add 95
// If character > 126, then subtract 95
// to put back within the range, and repeat as needed
// all printable characters are between this range
// ' ' is the 1st printable character (32)
// '~' is the last printable character (126)
note: subtracting values from the char will cause an overflow.
the prototype is: void subtracting(char array[], int size, int value)

C/C++ :: Storing IPv6 In Character Array?
Jul 11, 2014Its been too long since I have had to fiddle bits and I am coming up short.
Bottom line is the new IPv6 ip address representation is of the format:
xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
These come to me as hex values for example:
2001:7D7E:0000:0000:111A:222B:333C:4444
I want to store this in a char array, of integers of size char_addr[16] where each byte represents the integer representation of each xx pair thus
char_addr[0]=32 (20) *note address above
char_addr[1]=1 (01)
char_addr[2]=125 (7D)
char_addr[3]=126 (7E)
char_addr[4]=0 (00)

char_addr[15]=68 (44)
So I am having trouble filling that char_addr array.
