Write a function which (normally) allocates new space for a double array. It should alter its pointer argument to point to the newly allocated space. The size of the array should be a second argument. If this argument is not a valid array size, allocate a single double instead of a whole array. An example call might be:

see explaination

Explanation:

void allocate(double *q,int size)

{

if(size<=0)

q = new double; //Allocates a single double

else

q = new double[size]; //Allocates an array of doubles

}

This function allocates new space for a double array. It alter its pointer argument to point to the newly allocated space.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
