C++ :: How To Load WAV Files In Vector Or Array
Feb 28, 2013How to load .wav files. Say there are several .wav files in a folder called "sounds" in "My Documents", what would be the steps on loading them in a vector or array. I'm thinking I should use a vector type of array to not worry for a fixed size.

Jan 14, 2013I have a buffer which has a virtual width of 1024 pixels with virtual height 768 pixels (actual width stored in GPU.GPU_screenxsize, height in GPU.GPU_screenysize (both uint_32)).
I currently use the following function to plot the pixels to the screen:
inline void GPU_defaultRenderer() //Default renderer {
uint_32 pixel;
int bufferx; //Buffer's x!
int buffery; //Buffer's y!
int bufferxstart; //Buffer's x start!
int bufferystart; //Buffer's y start!
int pspx;
[Code] ...
How to combine the pixels together (blend them into one goal pixel) to get a better view? (Currently it takes the bottom right pixel of the area that represents the goal pixel).
So (x1,y1,x2,y2)->(pspx,pspy) = (bufferystart,bufferxstart,buffery,bufferx)->(pspx,pspy).
Atm this is (x2,y2)->(pspx,pspy)
Btw the pixel format is uint_32 RGBA (only RGB used atm). The psp_graphics_putpixel draws it onto the real VRAM. PSP_SCREEN_ROWS and PSP_SCREEN_COLUMNS represent the destination screen (the real screen)'s height and width in pixels.

C++ :: Read All Pixels From Bitmap Into One Big Array
Oct 21, 2013I need to be able to take a bitmap e.g. "untitled.bmp" (bit depth: 24) and loop through every pixel from top left to bottom right and find the rgb (or hex) value for each pixel e.g. (255,255,255) for white and store this rgb (or hex) value in a two-dimensional array depending on its [column]and[row].

C++ :: How To Read Pixels From X / Y Coordinate Using VGA Register Values
Aug 4, 2013How to read pixels from an x,y coordinate using the VGA register values?
byte readVRAMdirect(VGA_Type *VGA, uint_32 start, uint_32 offset) //Used in 256 color mode!
{
if (!VGA->VRAM_size) return 0; //No size!
return VGA->VRAM[SAFEMOD((start*4)+offset,VGA->VRAM_size)]; //The full protected offset!
[code]....
getVRAMScanlineStart(VGA,y) gives the offset register multiplied by 2 (shl 1), multiplied with the current memory address size (byte, word or dword) multiplied by the scanline. 256-color mode is already working. GETBIT gives a bit #(0-7) of a specified byte.
writeVRAMplane & readVRAMplane are used by the CPU to write data to VRAM (address 0xA000:xxxx-0xBFFF:xxxx), determined by the memory read and write modes(working) and the odd/even, planar or chain4 enable mode (working).how to get the 16 color and interleaved shift mode working?

C++ :: VGA VRAM Graphic Mode Reading / Writing Pixels?
Jan 21, 2013tell me where the errors in the below code are?
Extra info:
getrowsize() gives the size of a row in bytes (see VGA CRTC register).
getVRAMMemAddrSize() gives the size of a pixel in memory (1=byte,2=word,4=dword)
set/getBitPlaneBit(startaddr,plane,offset,bit[,on when writing]) sets/gets a bit on a specific bit plane offset (start addr is the start address register from VGA,
plane is the plane to read/write,
offset is the offset within the plane,
bit is the bit to read/write (0-7),
[on(when writing) is the value of the bit)]

C++ :: How To Extract And Modify Sub-Vector
Jun 17, 2014I have a std::vector<int> and I want to modify subset of the elements. I thought I might be able to use:
std::vector<int> a = { 1,2,3,4,5,6,7,8,9 };
std::vector<int> b(&a[3],&a[7]);
for(auto& each : b) {
each++;
}
for(auto& each : a) {
std::cout << each << "
";
}
but that didn't work. The elements of 'a' retain their original values. Then, I thought, "Ooo, maybe I could make 'b' a reference." Nope. What approach would be to access a subset of a vector for potential alteration?
C++ :: Extract Comments From C File
May 21, 2014I need to extract comments from a C file, which are usually marked with " /* This is a comment */ ". It seems to me that I need to calculate first at what position is the / and then ask it if on the very next position to the / operand is the *, if it is then I need check where is the next * and if / operand is immediately next to it. At last I need to take everything between values that the first and second * have. But I don't know how to write that in code.
This was supposed to be done in c++.

C :: Parsing A Line To Extract A Particular Substring?
Mar 14, 2014Suppose I have read a line from an ASCII file with fgets(). Now I want to parse the line, which looks something like this: Code: # John Q. Public et al. 2014, to be submitted The name, "John Q. Public" is what I want. However, the name can be anything, consisting of 1 or more tokens separated by spaces. it could be "John" Or "John Public", or "Thurston Howell the 3rd", or etc... Bascially, I need to get the entire substring between the first hash mark, and the "et al" in the line. I tried this: Code: sscanf(line,"# %s et al.",name); But I can only get the first token (which, in this case, is "John").

C/C++ :: Search In File And Extract Content Between 2 Strings
Jun 8, 2014I need to develop a simple program, i have 2 variables (begin, end), and i need to search in a file, And extract the string between the Begin and the End variables to a new File, For Example:
my text file: file.txt:
some text here<StartHere>more text here</EndHere>text text
C++ Program:
//Declear 2 variables
strcpy_s(begin, string("<StartHere>").c_str());
strcpy_s(end, string("</EndHere>").c_str());
//And now, search in the Text file, And Extract the text between the begin string and the End string.
