Question

If ptr is an integer pointer, writeC++ statement to allocate memoryfor an integer number and initialise it with 12.​

Answer 1

Answer:

Here is a short program to demonstrate it :

int main() {

int *p = new int;

*p = 12;

cout<<*p<<endl;

}

Output : 12

Explanation:

The pointer variable p is stored on the stack memory and the int it points to (which is nothing but the address of allocated memory) is stored on heap memory.
