//include library headers
#include <stdio.h>

void main()
{
    // constant variable
    const int SIZE = 5;

    // memory allocation using malloc
    int* ptr = (int*)malloc(SIZE * sizeof(int));

    // using address of operator to store values
    *(ptr) = 10;
    *(ptr+1) = 20;
    *(ptr+2) = 30;
    *(ptr+3) = 40;
    *(ptr+4) = 50;

    // printing the values of ptr vector
    for (int i=0; i<SIZE; i++)
        printf("%d ", *(ptr+i));

    // memory deallocation using free()
    free(ptr);
