dynamic memory allocation in c++ with example program pdf
Example 1: what is dynamic memory allocation in c++
In the dynamic memory allocation the memory is allocated during run time.
The space which is allocated dynamically usually placed in a program segment which is known as heap.
In this, the compiler does not need to know the size in advance.
In C++, dynamic memory allocation means performing memory allocation manually by programmer.
It is allocated on the heap and the heap is the region of a computer memory which is managed by the programmer using pointers to access the memory.
The programmers can dynamically allocate storage space while the program is running but they cannot create a new variable name.
Example:
Example 2: dynamic memory allocation in c++
char* pvalue = NULL;
pvalue = new char[20];
