as the example below:

#include

main()
{
struct array1
{
char name[30];
}details[10];
}

ok, now there got 10 arrays, what if i entered all the array (10 names), and i need to delete any of it, then how?

Well that's why arrays aren't always used because you run into those kind of problems.
But if you have 10 elements in the array and you want to delete the 5th element. Then you will have to move the 6th to the 5th, the 7th to the 6th, etc.... And if you want to add an element in the array you will first have to move the rest over one place to make room for the new element. In your example each element in the array is only 30 bytes and there are only ten of those records so shifting those back and forth won't be that much of a drain. But if your records start getting larger you might want to look into Linked Lists.

ok, I understand it! thanks!
