  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<...

C++ 14 !! We use Following code to Build c++14 Build with System in Sublime Text 3 : { "cmd" : [ "g++.exe" , "-std=c++14" , "${file}" , "-o" , "${file_base_name}.exe" , "&&" , "${file_base_name}.exe<inputf.in>outputf.in" ] , "selector" : "source.cpp" , "shell" : true , "working_dir" : "$file_path" } STEP : 1 Open New build System as mention in above picture... STEP : 2 Copy above code and Save it as name = c++14 This file name is save under JSON(******) package.
