//! \file Homework.cpp

#include <vector>

int main()
{
// declare the vector
std::vector<float> rgbArray;

// resize it to the dimensions you want
rgbArray.resize( 800 * 600 * 3 );

// ... do something cool

// resize the vector to 0 to clear and delete
rgbArray.resize( 0 );

return 0;
}

Thanks for the prompt answer. Trying it out now.:)

Sorry, I like a little organization in my code:

#include <vector>

// Not a very good idea in C++, but ok for this example
#define X_RES 800
#define Y_RES 600
/////////////////////////////////

// Store a RGB structure so you don't have to
// "think" about where you are in the array.
typedef struct {
float r;
float g;
float b;
} RGB;

int main()
{

std::vector<RGB> rgbArray;

rgbArray.resize(X_RES * Y_RES);

// do something cool.. but now, you
// can index the array with meaning!
// rgbArray[0].r = some red value for the first pixel;
// rgbArray[0].g = some green value for the first pixel;
// rgbArray[0].b = some blue value for the first pixel;

rgbArray.resize( 0 );

return 0;

}
