Dynamic memory allocation program in C code example
Example 1: dynamic memory allocation
int *p = new int; // request memory
*p = 5; // store value
cout << *p << endl; // Output is 5
delete p; // free up the memory
cout << *p << endl; // Output is 0
Example 2: dynamic memory allocation in c++
#include <iostream>
using namespace std;
int main () {
double* pvalue = NULL; // Pointer initialized with null
pvalue = new double; // Request memory for the variable
*pvalue = 29494.99; // Store value at allocated address
cout << "Value of pvalue : " << *pvalue << endl;
delete pvalue; // free up the memory.
return 0;
