sum&avg between two integer by using while loop

#include <stdio.h>
int main()
{
    int n,sum=0;
	float avg;
	printf("Input the 2numbers : \n");
	int i=1;
	while (i<=2)
	{
                printf("Number-%d :",i);
        i++;
		scanf("%d",&n);
		sum +=n;
	}
	avg=sum/2.0;
	printf("The sum of 2 numbers is : %d\nThe Average is : %f\n",sum,avg);
 return 0;
