Template for C++ Program

C++ is a very important language in competitive programming because C++ include flexibility of C and have extended STL template library.You can use C++ easy and and quick way if you have a template file. A template file contains a format and necessary code which is required frequently in competitive programming.You can save a lot of time by using template file because it takes some time if you have to include another header and define some more macros.

Here I am giving a simple template file according to my convenience.You can edit it or generate another file according to yours.

1. #include<iostream>
2. #include<cstdio>
3. #include<bitset>
4. #include<vector>
5. #include<cmath>
6. #include<queue>
7. #include<map>
8. #include<set>
9. #include<list>
10. #include<stack>
11. #include<string>
12. #include<cstdlib>
13. #include<cstring>
14. #include<algorithm>
15. 
    
16. using namespace std;
17. 
    
18. #define fori(i,n) for(i=0;i<(n);++i)
19. #define forin(i,s,n) for(i=(s);i<=(n);++i)
20. #define forn(i,n) for(i=(n-1);i>=0;--i)
21. #define forni(i,n,e) for(i=(n);i>=(e);--i)
22. #define MAX(a,  b) ((a) > (b) ? (a) : (b))
23. #define MIN(a,  b) ((a) < (b) ? (a) : (b))
24. #define ABS(X) ( (X) > 0 ? (X) : ( -(X) ) )
25. #define SQ(X) ( (X) * (X) )
26. #define nil NULL
27. #define itr iterator
28. #define pb push_back
29. #define mod 1000000007 //10^9+7
30. #define P printf
31. #define S scanf
32. //#define getchar getchar_unlocked  //Uncomment this if you are going to use fast i/o
