A Cpp Header for sorting

Have included 6 sorting algorithms-
1.Selection sort
2.Merge sort
3.Quick sort
4.Heap sort
5.Bubble sort
6.Insertion sort

Specifics

The headers can be added by

#include"sort.h"
#include<sort.h> --->if sort is copied to system header directories

Header sort.h will include all the sorting algorithms specified

sorting algorithms can be called as shown below

bubble_sort(a,n);
insertion_sort(a,n);
heap_sort(a,n);
merge_sort(a,n);
quick_sort(a,n);
selection_sort(a,n);

g++ main.cpp --->if sort.h and main.cpp are in the same folder
g++ -I /path/to/sort main.cpp --->if main.cpp and sort.h are in different folders

Planning to add Radix sort.
Other are welcome to suggest and add.
If bugs arises please inform and correct
