Does a dynamically allocated array return from a function causing a memory leak?

I ask this question to get rid of the confusion that I experienced about the next program. I know that using an array in certain contexts will cause the array to decay to a single pointer to its first element. I have a function that returns this array by pointer (this function is created using new[]). Will the array decay, forcing the pointer to point to only the first element? Here is an example:

int *foo() {
    int *t = new int[10];

    return t;
}

int main() {
    int *p = foo();
}

There is confusion here. I do not know if it points to pthe first element or to the entire array. Therefore, I have the following questions:

• Does the array return a pointer, leading to its decay (and, therefore, causes a memory leak)?
• p ?
• delete[] on p undefined, ?
