DMA malloc in Pointer.

 DMA is a Dynamic Memory Memory Allocation using to declare memory address.

DMA have four function :::
1. malloc()
2. calloc()
3. realloc()
4. free()

* Malloc Example code *

#include<bits/stdc++.h>

#include<stdio.h>

#include<stdlib.h>

using namespace std;

int main()

{

int i,n,min,max,j; // for allocate memory ....

cout<<"Enter the number of items\n";

cin>>n;

int *ptr; // for pointer.......

ptr=(int *) malloc(n* sizeof(int)); // allocation of the memory n*4 bytes of int 

if(ptr==NULL) 

{

cout<<"Memory not allocated\n";

exit(0);

}

else {

cout<<"Memory successfully allocatedd\n";

for(int i=0;i<n;++i){

scanf("%d",(ptr+i));

}

}

cout<<"The elements of pointer are \n";

for(int i=0;i<n;++i){

printf("%d\t",ptr[i]);

}

max=ptr[0];

for(i=0;i<n;++i){

if(max<ptr[i]){

max=ptr[i];

}

    }

cout<<max<<"\n";

min=ptr[0];

for(i=1;i<n;++i){

if(min>ptr[i]){

min=ptr[i];

}

    }

cout<<min<<"\n";

return 0;

}
