array removal doubt

gajji2020 (13)
I have a basic question i.e i have an integer array with numbers from 1 to n.... Whenever i get a value called no,i should delete the element in the array at this position(no)... And push the other numbers after this deleted number before by one... Can you write a code snippet for me....?

NO. Do your own homework.

Try something like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
 
#include <iostream>
#include <cstring>
using namespace std;

int main()
{
	int arr[] = {1,2,3,4,5,6,7,8,9,0};

	cout << "Before: ";
	for (int i = 0; i < (sizeof(arr)/sizeof(int)); i++)
		cout << arr[i] << " ";
	cout << endl;

	// doing magic here
	memcpy(arr+4, arr+5, sizeof(arr) - sizeof(int)*5);

	cout << "After: ";
	for (int i = 0; i < (sizeof(arr)/sizeof(int)); i++)
		cout << arr[i] << " ";
	cout << endl;
}
 
Before: 1 2 3 4 5 6 7 8 9 0
After: 1 2 3 4 6 7 8 9 0 0




Helps? 0 marks here like in a c-string simply an end of content.

And please do not multipost in forums just because you do not get a satisfying answer. If its no homework its not urgent, is it?

LIAR. This is a basic homework question, taught in CS 101 or earlier. And you blatently ask we do such an easy thing for you! Why would anyone trust you to write software?

@maikel
Do you really think that it is useful to giving a solution pretty-packaged for someone who won't even bother to try? Can you give me $100?


More and more I really am considering going the way of Grey Wolf. This is absurd.

Gajji, If you had posted your code showing that you had made an attempt but failed, then you may have got a better response to your question. If it is homework, an exercise from a book, or something you need to do yourself, makes little difference; just show that you are not after a free meal.
