Dynamic 2 dimensional array with new?

I want to create a dynamic 2 dimensional array like this

Code:

---

parray = new z[x][y];

---

Why dosen't new allow this? shouldn't it be possible for new to allocate memory the size of x*y and return a pointer to z[0][0]?

Example of 2D memory allocation

Code:

---

int **ptr;
ptr=new int *[10];//creates an array pointer
for(int i=0;i<10;i++)
p[i]=new int [5];//creates space for each row

---

make sure u delete the mempry after use

thanx

To delete that memory:

Code:

---

for(int i=0;i<10;i++)
    delete p[i];
delete [] p;

---

Not quite. Should be:

Code:

---

for(int i=0;i<10;i++)
    delete [] p[i];
delete [] p;

---

I think what dwks is saying is right

>> delete [] p[i];

nice catch

yes...it should be

Code:

---

delete[] p[i];

---

Oops. Yes.

Code:

---

delete [] p[i];

---

Sometimes oops just isnt good enough.

maybe oops[100] would do. :)

Perhaps you were thinking of [50]. 10*5 = 50.
