Answer 1

You have to use long long as your data type of the array. because You are going to store out-range numbers of the integer range.(-2,147,483,648 to 2,147,483,647) And declaration of int i should be before the for loop.

#include

int main(void)
{

    int n=50;
    long long array[n];
    array[0]=0;
    array[1]=1;
    printf("%lli\n",array[0]);
    printf("%lli\n",array[1]);
    int i;
    for(i=2;i
