C Program for Binary Search Tree Creation and Traversals. Binary Search Tree is a Tree which has the following properties, 1.The left sub tree of a node contains smaller nodes than a root node. 2.The right sub tree of a node contains greater nodes than a root node. 3.Both the left and right sub trees must also be binary search trees. There are three types of tree traversals, Preorder, Postorder, and Inorder. Read more about C Programming Language .

INSERTION SORT PROGRAMME>>>
Q-:WRITE A PROGRAMME TO DO INSERTION SORT?
ANSWER-:
#include
#include
int a[10],b;
int i=0,count;
void order()
{
for(i=0;i>ch;
while(ch=='y')
{
cout<<"enter the element";
cin>>a[i];
count=i++;
cout<<"Press Y to enter the element in the arrayn";
cin>>ch;
}
order();
for(i=0;i<count+1;i++)
{
cout<<a[i]<<" ";
}
getch();
}
Very good article. I definitely appreciate this website.
Keep writing!
Using encryption all data is encrypted.
Hi!
Sure. As you may be aware, I’m doing some site-wide changes. I will take up program request soon after that’s done.
Encryption programs are on the list.
Thanks,
