Write a program that reads the number N of integers, then read N consecutive integers starting from 0 with one integer missing (integers could be entered in any random manner) and finds the missing value.

Example: 

• Enter the number of elements: 9
• Enter the number of one line:  1 5 0 9 2 6 3 8 7 
• Missing element 4

Hint: \(\sum_{i=0}^N=\frac{N\times(N+1)}{2}\)

#include <stdio.h>
#define NBMAX 100

void main()
{
	int N, sum=0 , i, nb;

	do{
		printf("Enter the number of elements: ");
		scanf("%d", &N);		
	}while(N<=0 || N>NBMAX);

	printf("Enter the number of one line: ");
	i=1;
	while(i<=N)
	{
		scanf("%d", &nb); 
		sum+=nb;
		i++;
	}

		
	/*the sum from 0...N is(N*(N+1))/2*/
	printf("\nMissing element %d.\n",((N*(N+1))/2)-sum);
}
